Abstract

A method for producing organic fertilizer and drinking water from manure comprises transporting primary liquid manure (1) to an accumulation tank (2), from which it is fed to a separation device (5) to obtain a primary liquid fraction (6) and a primary solid fraction (7). The solid fraction (7) is dewatered using a screw press (8) and a screw extruder (9), ground in at least one grinding device (33), and subjected to supercritical fluid extraction in device (21) to extract 80-100 % of the organic components (31), yielding a dry residue (25). The liquid fraction (6) passes through a primary filtration section (10) with filtration devices (11), is sterilized and cooled in section (12) using devices (13.1, 13.2), filtered by ultrafiltration in section (14) using device (15), and treated in a reverse osmosis unit (16) to produce drinking water (17) and a salt concentrate (18). The concentrate (18) is mixed with the extract (31) and ethanol (38) in vessel (34), and the resulting mixture (22) is separated in section (35) by high-performance liquid chromatography device (23), followed by vacuum evaporation in device (24) to recover ethanol (39) and isolate concentrated solutions (40).

[0005] HALUSHKO’S ENVIRONMENTALLY FRIENDLY METHOD OF PRODUCTION OF ORGANIC FERTILIZERS, CRYSTALLINE CARBON, DRINKING WATER AND

[0006] ELECTRICITY FROM MANURE

[0007] Scope of application.

[0008] The invention relates to the chemical industry and agriculture, namely to the production of organic fertilizers by treating and processing the manure of domestic animals and birds using technological, physical and chemical processes. The invention provides an environmentally friendly method for producing organic fertilizers, crystalline carbon, drinking water and electricity from manure.

[0009] Prior art.

[0010] In the process of constantly increasing development of agricultural production and livestock industry, a large amount of biological organic waste such as manure (meaning livestock manure and poultry manure) is generated. Untreated livestock and poultry manure is a rather toxic mixture of substances that can contaminate ground and surface water, soil, causing serious environmental pollution problems, including greenhouse gas emissions. In addition, livestock and poultry manure is usually contaminated with pathogenic bacteria, heavy metals and other toxic and harmful substances that negatively affect the environment, including animals, fish, and, of course, can have a harmful effect on human health.

[0011] There are many known ways of processing manure to produce organic fertilizers and / or fuel and energy materials. But primary liquid manure is known to be difficult to process efficiently.

[0012] Nowadays, organic fertilizers made from manure are available in the market. But they have many significant disadvantages, namely: - When stored, untreated manure naturally emits large amounts of greenhouse gases, increasing the greenhouse effect;

[0013] - When fertilizer in the form of unprocessed liquid manure or partially processed (dried and compacted) granular manure is applied to the soil, the natural release of greenhouse gases into the atmosphere continues until the manure is completely decomposed;

[0014] - When fertilizer is applied to the soil in the form of unprocessed liquid manure or partially processed (dried and compacted) granular manure, it is impossible to maintain the exact dosage, and even more so, the specific dosage of certain necessary nutrients for a particular crop and at a particular phase of plant development;

[0015] - Not all nutrients applied with untreated or partially treated manure are assimilated by plants in the first year of their life, and the remaining, unused manure substances are partially leached by water into rivers, lakes and groundwater, significantly polluting them;

[0016] - Other types of liquid fertilizers that exist on the market, usually have a formula that is not perfect and absolutely optimal for specific plants / crops, which does not allow to provide the most correct balanced and timely complex nutrition to plants / crops.

[0017] Preliminary studies show that efficient, full-fledged and environmentally friendly processing of only cow manure produced by animals in the world will fully meet the needs of world agriculture in organic highly concentrated fertilizers. The overproduction of nitrogen fertilizers may amount to 157%, phosphate fertilizers - 230%, potash fertilizers - 1054%. This level of overproduction will allow to satisfy in excess the demand for these fertilizers in countries and regions where there is a significant deficit of such substances as of today. This will increase overall crop yields and may indirectly have a positive impact on solving food problems in hungry countries. At the same time, there could be a significant reduction in greenhouse gas emissions from the mining and processing industries involved in the production of chemical fertilizers.

[0018] Thus, the creation of an effective harmless method of production of organic fertilizers, pure crystalline carbon, drinking water and electricity through environmentally friendly processing of animal and poultry manure, which allows to completely eliminate greenhouse gas emissions into the atmosphere and other harmful substances that contaminate the soil, rivers, lakes and groundwater, is an urgent and important task.

[0019] A method of extracting at least one nutrient from raw manure is known, which includes collecting and chopping (cutting) raw manure to a desired length in order to obtain slurry (liquid manure), transporting the liquid manure to an accumulation tank for primary treatment, mixing with a stirring device, transporting the liquid manure from the accumulation tank and pre-treatment with a pump for further separation of the liquid manure into a solid and a liquid fraction, including filtration of the liquid fraction into a solid sludge and a liquid fraction. The purpose of this invention is to achieve recovery (extraction) of nutrients from agricultural manure, in particular by a method of separating raw liquid manure into a solid sludge and a liquid fraction, with a decrease in the phosphorus (or other nutrients) content in the liquid fraction and an increase in the solid sludge. But this method does not provide for obtaining various highly concentrated solutions of mono-fertilizers with high concentrations of nutrient elements or monofertilizers in the form of crystals, including those based on nitrogen, phosphorus, potassium, which does not allow to create various fertilizers with any formula for targeted use in relation to various specific crops.

[0020] A method of producing biofuels by subcritical / supercritical liquefaction treatment of chicken manure is known, comprising: collecting, stockpiling, drying, grinding and sieving fresh chicken manure to produce a powdery mixed material, transporting the ground solid powdery fraction to a subcritical / supercritical liquefaction unit, where the solid powdery fraction is mixed with a liquefaction solvent, and at high pressure and high temperature for a period of time, the liquefaction solvent is mixed with a liquefaction solvent. This invention is intended to produce biofuels by subcritical / supercritical liquefaction treatment of chicken litter, with simultaneous harmless disposal of chicken litter and conversion of heavy metals (Pb, Zn, Cu, Mn, Ni, Cd and Cr) that may be in chicken litter into relatively stable forms of heavy metals by the addition of stabilizers, thereby greatly reducing the risk of environmental pollution. But the present invention is not intended to and does not produce organic fertilizers for crops, pure crystalline carbon and drinking water from chicken manure.

[0021] A method of producing organic fertilizers by environmentally friendly processing of livestock and poultry manure is known, which is described in the invention "Environmentally friendly and highly efficient method of processing livestock and poultry manure and the resulting product" (Patent of the People's Republic of China for invention No. CN117534509A, IPC A01 C21 / 00; C05 F3 / 00; C05 G5 / 20, published on 09.02.2024 [3]). The method includes: collecting and accumulating livestock or poultry manure, bringing the water content of the livestock or poultry manure to 76-78% (i.e., creating "liquid manure biomass"), treating the liquid manure biomass with adjusted water content in a closed environment for 30-120 minutes at a temperature of 120-175 °C and a pressure of 4.3-4.9 MPa, and separating the solid and liquid fractions using a filter press to produce a highly effective biogenic solid organic fertilizer and a liquid organic fertilizer. This patent states that the beneficial effects of this method are: simple and economical production technology, low cost of the resulting solid and liquid organic fertilizer, no pollution and zero emissions (all solid, liquid waste and exhaust gas are recycled), saturation of the solid and liquid fractions with nutrients with extremely low heavy metal content. In this method there are no steps of double moisture reduction, double filtration of liquid fraction (including no ultrafiltration step), high-performance liquid chromatography. Thus, organic fertilizers obtained by this method are not balanced, and their application will not provide plants with balanced nutrition (some elements may be insufficient and some elements may be in excess). When manure is composted and the granular solid fraction is applied to the soil, greenhouse gases will be emitted and the greenhouse effect will be enhanced. Fertilizer produced by this method and applied to the soil will not be 100% utilized by plants in the first year after application and will leach as sediment into rivers, lakes and groundwater and contaminate them. In addition, this method does not allow to obtain various highly concentrated solutions of mono-fertilizers with high concentrations of nutrient elements or mono-fertilizers in the form of crystals, including those based on nitrogen, phosphorus, potassium. Accordingly, this method does not allow the creation of various universal fertilizers with any formula for targeted use with respect to various specific crops at different phases of plant development.

[0022] A method for utilizing waste from a large livestock farm is known, comprising at least the following steps: collecting and accumulating primary liquid manure of livestock and poultry, separating the solid and liquid fractions of the manure, mixing with crop straw, composting, fermenting, drying, crushing and granulating the solid fraction to make an organic fertilizer; treating and ultrafiltrating the residual manure liquid remaining after the separation into two fractions, collecting the residual liquid for future manure management. The method also includes the steps of prior specific regulation of animal feeding and deodorization of the farm premises to reduce harmful substances in future animal and poultry manure. Accordingly, this method is designed to achieve the reduction of primary sources of manure pollution (feed, drinking water, room treatment) together with the subsequent comprehensive treatment and cyclic utilization of large-scale pollution of the external environment by animal waste. But, organic fertilizers obtained by this method of disposal are not balanced, and their application will not provide plants with balanced fertilizers (some elements in the composition of the fertilizer may be insufficient, and some elements may be in excess). Composting the manure and applying the granular solid fraction to the soil will release greenhouse gases and increase the greenhouse effect. Fertilizer produced by this method and applied to the soil will not be 100% utilized by plants in the first year after application and will leach as precipitation into rivers, lakes and groundwater and contaminate them. In addition, this method does not allow to obtain various highly concentrated solutions of mono-fertilizers with high concentrations of nutrient elements or mono-fertilizers in the form of crystals, including those based on nitrogen, phosphorus, potassium. Accordingly, this method does not allow the creation of various universal fertilizers with any formula for targeted use with respect to various specific crops at different phases of plant development.

[0023] The method of production of organic fertilizers by processing the manure of domestic animals and birds is known, which is described in the utility model "Method of processing liquid manure and effluents of animal complexes" (Patent of Ukraine for utility model No. 73066, IPC A01K 1 / 00, published on 10.09.2012, bulletin No. 17 [5]). The described method provides for collection and transportation of primary liquid manure (and effluents of animal complexes) to the accumulation tank, and further from the accumulation tank transportation to the separation device (separator), where separation of primary liquid manure into two fractions - primary liquid fraction and primary solid fraction is carried out, at the same time primary moisture reduction of primary solid fraction is also carried out. Further, secondary moisture reduction of the primary solid fraction is carried out and used as a fuel material. The primary liquid fraction is decontaminated, biologically treated and applied as a liquid fertilizer in irrigated fields. From the detailed description of this method it is obvious that it does not allow for maximum qualitative processing of all parts of liquid manure and effluents of animal complexes, including liquid fraction, solid fraction and dry organic residue. Accordingly, this method of processing of liquid manure and effluents of animal complexes does not provide for and does not allow obtaining various highly concentrated solutions of monofertilizers with high concentrations of salts or mono-fertilizers in the form of crystals, including those based on nitrogen, phosphorus, potassium. And, as a consequence, this method does not allow the creation of different fertilizers with any desired formulation for targeted use with respect to various specific crops. Fertilizers obtained by this method and applied to the soil will not be 100% used by plants in the first year after their application to the soil and will be leached as precipitation into rivers, lakes and groundwater and clog them.

[0024] Based on an analysis of the prior art, the following can be inferred:

[0025] The goals and possibilities of the known methods of organic fertilizer production by processing animal manure and / or poultry droppings are only partial extraction of substances suitable for fertilizers from manure. And also only partial utilization of methane, carbon dioxide, hydrogen sulphide and other environmentally harmful substances emitted during storage, composting and land application - derivatives of manure.

[0026] In the known described methods of organic fertilizer production for processing and utilization of livestock and poultry manure, several different known steps of this technological process are generally used in different cases. Such steps are: collection, accumulation, mixing of manure, partial removal of moisture, separation and partitioning into liquid and solid fractions, grinding, filtration, ultrafiltration, disinfection (sterilization), treating and exposing the mixture in a subcritical / supercritical (using supercritical water) liquefaction device at high pressure and high temperature for a period of time, evaporating the liquefaction solvent, producing mixed solid and / or liquid fertilizers, biofuels or solid (pressed fuel materials). But the said methods or combination thereof are not used in the known patents to produce stand-alone concentrated monofertilizers or concentrated compound ingredients for making complex fertilizers.

[0027] Each individual method described uses only some of the specified steps of manure processing for fertilizer production, without creating and implementing the maximum possible cycle of technological treatment, processing and disposal of manure. These known methods do not achieve the most environmentally friendly processing and disposal of manure and do not allow the production of various highly concentrated mono-fertilizer solutions with high concentrations of nutrient elements, which can be used to make water- soluble crystals and / or granular fertilizers for specific defined crops, with the possibility of applying the fertilizer at precise dosages of up to 1 gram at specific and necessary times for the plants. Furthermore, in said known processes for processing and / or utilizing manure, the production of pure crystalline carbon and drinking water is not contemplated and is not possible. And also in said known processes, the processing and / or utilization of manure does not provide for the use of electricity, which would be produced from the mixture of pyrolysis gases obtained after the pyrolysis process of dry manure residues.

[0028] The technical objective of the invention is to provide a method of producing organic fertilizers by environmentally friendly processing and utilization of poultry and animal manure using processes of accumulation, mixing, transportation, separation, moisture reduction, sterilization, two-stage filtration, reverse osmosis, supercritical extraction, high-performance liquid chromatography, evaporation, and other related processes with respect to liquid manure and its components.

[0029] A positive technical result of the implementation of the method proposed in the invention is obtaining from the manure of domestic animals and birds separated and isolated individual substances in the form of highly concentrated solutions of monofertilizers with high concentrations of nutrient elements, including macronutrients N, P, K, Ca, Mg, S, and trace elements Si, Cu, Zn, Fe, Mn, Mo, Se, V, which are completely purified from viruses, bacteria and other environmentally harmful components of raw manure, and which, as a result, are self-contained mono-fertilizers and constituent ingredients for complex fertilizers for crops, can be used to make water-soluble crystals and / or granular and / or liquid fertilizers for specific defined crops with the ability to apply the fertilizer at a precise dosage of up to 1 gram at a specific required time.

[0030] An additional technical result of the embodiment of the invention is:

[0031] - drinking water production;

[0032] - utilization of dry organic residue of manure and production of pyrolysis gas mixture from it;

[0033] - utilization of the resulting pyrolysis gas mixture to generate electricity, which fully covers the energy demand for processing the manure that goes to the processing plant; the excess electricity is directed to the general energy grid (this indirectly reduces greenhouse gas emissions);

[0034] - production of pure crystalline carbon from the dry organic residue of manure and its realization for use in other industries.

[0035] The manure processing process produces only useful and safe products and does not produce waste that requires disposal.

[0036] Disclosure of the invention.

[0037] The stated problem is solved by the fact that the environmentally friendly method for production of organic fertilizers, crystalline carbon, drinking water and electricity from manure includes transportation of primary liquid manure 1 to the accumulation tank 2, where accumulation, mixing and further transportation of primary liquid manure 1 from the accumulation tank 2 to the separation device 5, where the primary liquid manure 1 is separated into primary liquid fraction 6 and primary solid fraction 7, and the moisture content of primary solid fraction 7 is reduced to 55% to 65% of moisture content, after which the two separated fractions 6, 7 are processed and treated independently of each other. At the same time, the primary solid fraction 7 is subjected to a temperature increase and a secondary moisture reduction to 5-10% moisture content by means of a screw press 8 and a screw extruder 9. At the shredding section 32, using at least one shredding device 33, the dehydrated primary solid fraction 7 is shredded. Next, the dewatered and pulverized primary solid fraction 7 is transported to a supercritical fluid extraction device 21 where 80% to 100% of the organic components present in the primary solid fraction 7 are extracted. At the same time, the temperature in the supercritical fluid extraction device 21 is from 40 to 90° C, the pressure is from 100 to 600 Atm, and the residence time is from 2.5 to 4 hours, resulting in an organic component extract 31 and a dry organic residue 25. The organic component extract 31 is transported to a mixing vessel 34. The dry organic residue 25 is extracted from the supercritical fluid extraction device 21 for further processing and disposal. At the same time, the separated primary liquid fraction 6 from the separation device 5, screw press 8 and screw extruder 9 is transported by pipelines to the primary filtration section 10, where at least one primary filtration device 11 is used for primary filtration of the primary liquid fraction 6 from solid mechanical impurities 30 with sizes up to 5 pm, which are further transported to the accumulation tank 2 of the primary liquid manure 1. The pre-filtered primary liquid fraction 6 is transported to the sterilization and cooling section 12. Using the sterilization device 13.1, it is sterilized for 2 to 10 seconds at a temperature of 120 to 180°C. It is then cooled to a temperature of 20 to 25°C for 2 to 10 seconds at a temperature of - 40 to - 60°C using the cooling device 13.2. Next, the primary filtered, sterilized and cooled primary liquid fraction 6 is transported to the ultrafiltration section 14, where solid mechanical impurities 30 up to 1 pm in size are filtered out of the primary liquid fraction 6 using the ultrafiltration device 15, which are further transported to the accumulation tank 2 of the primary liquid manure 1. Twice filtered primary liquid fraction 6 is transported to the reverse osmosis unit 16, where by means of reverse osmosis process the primary liquid fraction 6 is separated into drinking water 17 and salt concentrate 18 in the quantitative ratio of drinking water 17 from 75% to 90%, salt concentrate 18 from 25% to 10%. The potable water 17 is transported from the reverse osmosis unit 16 for further use. The salt concentrate 18 is transported to a mixing tank 34, into which ethanol 38 from the ethanol tank 20 is also transported. In the mixing vessel 34, the salt concentrate 18 and the extract of organic components 31 are mixed with ethanol 38, in a ratio of 1 :10 to 1 :15, wherein 1 part is a mixture of the salt concentrate 18 and the extract of organic components 31 and 10 to 15 parts is ethanol 38, resulting in a complex mixture 22 of ethanol 38, water, salts, and organic components. The complex mixture 22 is transported to a separation section 35, where, using a high-performance liquid chromatography device 23, the complex mixture 22 is separated into separate substances in the form of separate solutions 36 of salts in ethanol 38 and water, which are transported separately from the high-performance liquid chromatography device 23 into separate containers 37. From the individual containers 37, the individual solutions 36 are transported to the vacuum evaporation device 24, where in the process of evaporation in vacuum there is a complete 100 % - percent extraction from each individual solution 36 of reduced ethanol 39, partial removal of water and formed separated and isolated as separate substances highly concentrated solutions 40 with high concentrations of macronutrients or trace elements, which from the vacuum evaporation device 24 are transported to individual containers 41. The recovered ethanol 39 is transported to a container with ethanol 20.

[0038] The proposed method is characterized by additional features.

[0039] Primary liquid manure 1 contains: pet manure or poultry litter, or a mixture of pet manure and / or poultry litter, or a mixture of manure or litter, or manure and litter with other substances of biological origin that are produced by domestic animals and / or poultry, including pet urea and / or poultry urea.

[0040] For the supercritical fluid extraction process from the dehydrated and crushed primary solid fraction 7, a liquid gas is used as a solvent: carbon dioxide or ethane or ethylene or propane or sulfur hexafluoride.

[0041] In the supercritical fluid extraction process, ethanol or methanol is used as a cosolvent.

[0042] To perform primary filtration with respect to the primary liquid fraction 6, one or more primary filtration devices 11 are used in the primary filtration section 10, wherein a single primary filtration device 11 is an auto-wash disk filter, and multiple auto-wash disk filters installed in series with varying degrees of filtration are used as multiple primary filtration devices 11.

[0043] Two or more plate heat exchangers, which are sterilization devices 13.1 and cooling devices 13.2, are used to carry out sterilization and cooling of the filtered primary liquid fraction 6 in the sterilization and cooling section 12. ,

[0044] In order to realize ultrafiltration of the primary liquid fraction 6 from solid mechanical impurities 30 up to 1 pm in size, an ultrafiltration device 15 is used in the ultrafiltration section 14 as an ultrafiltration device 15 with silicon carbide membranes.

[0045] After primary filtration and ultrafiltration of the primary liquid fraction 6, the primary filtration device 11 and the ultrafiltration device 15 are washed, and all, remaining and washed out of the primary filtration device 11 and the ultrafiltration device 15 solid mechanical impurities 30 are transported to the accumulation tank 2 of the primary liquid manure 1.

[0046] In the separation section 35, a vacuum evaporator with a falling film evaporator is used as the vacuum evaporation device 24 to perform vacuum evaporation of ethanol 38 and water from separate solutions 36.

[0047] After secondary moisture reduction, the primary solid fraction 7 is further dried.

[0048] The dry organic residue 25 obtained after supercritical fluid extraction is transported from the supercritical fluid extraction device 21 to a pyrolysis unit 27, where the dry organic residue 25 is processed to produce a mixture of pyrolysis gases 28 and pure crystalline carbon 29.

[0049] The pyrolysis gas mixture 28 is transported to a power generation device 26, where electricity 44 is generated from the pyrolysis gas mixture 28, or the pyrolysis gas mixture 28 is transported to a gas transportation system 42.

[0050] Inventive level.

[0051] The proposed method is designed to produce organic fertilizers by environmentally friendly processing of manure of domestic animals and poultry raised on farms. The method involves the use of a maximum number of manure treatment / processing steps, including the use of supercritical fluid extraction to produce an extract from the primary solid fraction 7 obtained from the primary liquid manure 1.

[0052] At the first stage, the primary liquid manure 1 is accumulated and mixed in the accumulation tank 2. After that, the primary liquid manure 1 is transported to the separation device 5, where the primary liquid manure 1 is separated (separated) into primary liquid fraction 6 and primary solid fraction 7, reducing the moisture level of primary solid fraction 7 to 55% - 65%. Further, by means of screw press 8 and screw extruder 9, the moisture content of the primary solid fraction 7 is further reduced to 5-10%. At the same time, due to friction, the temperature is raised to 70-90° C and the primary solid fraction 7 and the primary liquid fraction 6 are partially sterilized. Thus, as a result of the first stage of treatment of the primary liquid manure 1, the primary solid fraction 7 with a moisture level of not more than 10% and the unfiltered primary liquid fraction 6 with the presence of solid mechanical impurities 30 are separated, which are obtained in the process of moisture removal at the separation device 5, screw press 8 and screw extruder 9. The primary liquid fraction 6 is transported by pipelines to the primary filtration section 10.

[0053] The method further comprises processing and treating the two separated fractions 6, 7 to a certain stage independently of each other using different processes. This allows each of the two fractions 6, 7 to be processed / processed more thoroughly than known similar methods in the following production steps.

[0054] In a next step, the maximally dehydrated primary solid fraction 7 is milled, and in some cases additional drying of the milled primary solid fraction 7 is applied to further remove moisture. In this step, the dewatered and milled primary solid fraction 7 is subjected to a supercritical fluid extraction process (in the supercritical fluid extraction apparatus 21), wherein the dewatered and milled primary solid fraction 7 is contacted with a solvent in the form of a liquid gas (carbon dioxide, ethane, ethylene, propane, sulfur hexafluoride) which is in a supercritical state at a pressure of 100 to 600 Atm and a temperature of 40 to 90 °C. The extraction time is 2.5 to 4 hours. During this time, 100% of all organic components that were in the primary liquid manure 1 are extracted from the primary solid fraction 7. Thus, at this stage it is possible to completely process the primary solid fraction 7 of the primary liquid manure 1 and obtain: extract of organic components 31 (which are further transported to the mixing tank 34) and dry organic residue 25 (which is extracted from the supercritical fluid extraction device 21 and sent for further processing and utilization to the pyrolysis plant 27). No waste requiring disposal and polluting the environment is generated. At the output of the pyrolysis unit 27, a mixture of pyrolysis gases 28 (which is used as fuel for electricity generation 44) and pure crystalline carbon 29 (described in more detail below) is obtained.

[0055] In parallel with the described step of treatment of the primary solid fraction 7, an independent step of treatment of the primary liquid fraction 6 is carried out. This step includes: pre-filtration of the primary liquid fraction 6 from solid mechanical impurities 30 having a size up to 5 pm, sterilization at a temperature of 120 to 180 °C for 2 to 10 seconds, cooling of the primary liquid fraction 6 to 20-25°C at a temperature of - 40 to - 60 °C for 2 to 10 seconds, repeated ultrafiltration from solid mechanical impurities 30 having a size up to 1 pm, and reverse osmosis process.

[0056] In the primary filtration section 10, one or more disk filters with automatic washing are used as the primary filtration device 11. In the ultrafiltration section 14, a device with silicon carbide membranes may be used as the ultrafiltration device 15. In the process of two filtrations and after washing of all said filters, all filtered from the primary liquid fraction 6 solid mechanical impurities 30 are transported to the accumulation tank 2 of the primary liquid manure 1. For sterilization and cooling of the primary liquid fraction 6, one or more plate heat exchangers may be used in the sterilization and cooling section 12.

[0057] Double filtration, sterilization and cooling of the primary liquid fraction 6 allows to obtain and send to the reverse osmosis unit 16 the primary liquid fraction 6, which is maximally purified from solid mechanical impurities 30 as small as 1 pm, which, in turn, allows to achieve the most efficient implementation of the reverse osmosis process and to extend the service life of the osmotic membranes.

[0058] As a result of the reverse osmosis process, the liquid fraction 6 is separated into desalinated and purified drinking water 17 and salt concentrate 18 in the quantitative ratio of drinking water 17 from 75% to 90%, salt concentrate 18 from 25% to 10%.

[0059] Thus, at this stage processing and separation of primary liquid fraction 6 and primary liquid manure 1 are realized, as a result of which the following are obtained: salt concentrate 18, drinking water 17 and solid mechanical impurities 30 up to 1 pm in size PCT / UA202 I '010)0 i 0- 501

[0060] 12 discharged 1 into the accumulation tank 2. No waste requiring utilization and polluting the environment is generated.

[0061] Drinking water 17 may be used for any of the practical uses that are applicable to drinking water.

[0062] Solid mechanical impurities 30 are mixed with the incoming primary liquid manure 1 in the accumulation tank 2 and continue to be cyclically processed. When implementing the proposed method, the solid mechanical impurities 30 are not accumulated in the accumulation tank, but continue to be cyclically processed together with the primary liquid manure 1.

[0063] Salt concentrate 18, ethanol 38 from ethanol tank 20, and organic component extract 31 are transported to mixing tank 34.

[0064] As a result of the several steps of the method described above, the individual extract of organic components 31 and salt concentrate 18 obtained after these steps of the method can be used as constituents of solid or liquid agricultural fertilizers. But, both the extract of organic components 31 and the salt concentrate 18 are multi-component complexes, which contain a large number of different trace elements and macronutrients (see Table 1) used for fertilizers. And these different elements are always found in the compositions of organic components extract 31 and salt solution 18 in a wide variety of uncontrolled ratios (depending on the chemical characteristics of the primary liquid manure 1). Thus, the use of the extract of organic components 31 and / or salt concentrate 18 as fertilizers or as constituents of fertilizers is totally irrational, because, using the extract of organic components 31 and / or salt concentrate 18, it is not possible to accurately dose and introduce, for example, specific beneficial substances for specific plants into the soil.

[0065] In order to achieve the possibility of obtaining highly concentrated substances for use as organic fertilizers or ingredients thereof, and in order to maximize the recycling and utilization of derivative substances obtained in the process of treatment and processing of liquid 6 and solid 7 fractions of separated primary liquid manure 1, the following step of the proposed method is carried out.

[0066] In the mixing vessel 34, the salt concentrate 18 is accumulated and mixed with ethanol 38 and with the organic component extract 31. Such mixing is carried out in the ratio of 1 : 10 to 1 :15 (where "1 " is a mixture of salt concentrate 18 and organic components extract 31, and "10-15" is ethanol 38) and a complex mixture 22 of salts, organic components, ethanol 38 and water (which is a part of salt concentrate 18) is obtained. In this case, the amount and ratio of water in the complex mixture 22 is not essentially important.

[0067] Ethanol 38 is a versatile solvent that is capable of mixing in arbitrary relationships with many different substances, including those of organic origin, including fats, oils, as well as salts, acids, esters, alcohols, organic solvents, water, and other substances. The properties of ethanol 38 allow the organic components of the organic component extract 31 and the salt solution 18 to be completely dissolved, and a complex mixture 22 of these substances to be obtained.

[0068] Further, the complex mixture 22 is transported to a separation section 35, where, using a high-performance liquid chromatography device 23, the complex mixture 22 is separated into separate substances in the form of separate solutions 36 of various salts in ethanol 38 and water. Said separate solutions 36 from the high-performance liquid chromatography device 23 are separately transported to separate containers 37, from which they are further transported to a vacuum evaporation device 24 for vacuum evaporation of ethanol 38 and water. Preferably, the vacuum evaporation device 24 is a vacuum evaporator with a falling film. During the vacuum evaporation process, there is a complete (100% - percent) extraction of the reduced ethanol 39 from each individual solution 36, and also a partial removal of water. As a result, various highly concentrated solutions 40 with high concentrations of macronutrients or trace elements are formed, separated and isolated as individual unit substances, which are transported from the vacuum evaporation device 24 to individual containers 41. The recovered ethanol 39 is transported to the ethanol container 20.

[0069] The resulting highly concentrated solutions 40 with high concentrations of macronutrients or micronutrients are designed to mix these nutrients in the necessary and precise proportions to produce fertilizers with predetermined formulas. Such fertilizers, based on highly concentrated solutions 40 with high concentrations of macronutrients or micronutrients created using the proposed method, can be produced in commercial quantities in the form of liquids, water-soluble crystals, granules.

[0070] Table 1 shows the possible chemical composition of elements (used to create fertilizers) in liquid manure of various domestic animals and birds. In addition to the elements listed in Table 1, poultry and animal manure contains a large number of trace elements. Table 1 In accordance with the proposed method, separating the primary liquid manure 1 into primary liquid 6 and solid 7 fractions, and treating and processing them independently separately, including, two-stage moisture reduction and liquid separation, grinding and supercritical fluid extraction in respect of primary solid fraction 7, as well as two-stage filtration (including ultrafiltration), sterilization, cooling and application of reverse osmosis in respect of primary liquid fraction 6, allow to extract up to 100% of salt concentrate 18 from primary liquid fraction 6 and also to extract 80-100% of organic components in the form of extract of organic components 31 from primary solid fraction 7. The resulting salt concentrate 18, organic component extract 31 and ethanol 38, according to the invention, allow for a complex mixture 22 in which the organic components and salts previously purified and extracted from the primary liquid manure 1 are dissolved. Using a high- performance liquid chromatography process, the complex mixture 22 is effectively separated into individual substances (individual solutions 36 of various salts dissolved in ethanol 38 and mixed with ethanol 38 in mixing vessel 34) which contain the macronutrients N, P, K, Ca, Mg, S, and the trace elements Si, Cu, Zn, Fe, Mn, Mo, Se, V.

[0071] Subsequent vacuum evaporation process allows to extract (recover) ethanol 39 and evaporate water from each individual solution 36 and, as a result, to obtain various highly concentrated solutions 40 with high concentrations of macronutrients or trace elements, including those based on nitrogen, phosphorus, potassium, iron, calcium, magnesium and various trace elements, which are maximally purified from various environmentally harmful components of primary raw manure including heavy metals. Highly concentrated solutions 40 with high concentrations of macronutrients or trace elements obtained by the proposed method are independent mono-fertilizers or components for complex fertilizers of agricultural crops. The highly concentrated solutions 40 with high concentrations of macronutrients or trace elements can be used in liquid, water-soluble crystalline, granular form as fertilizers for specific defined crops. The high concentration of a particular chemical element in each individual high-concentration solution 40 allows for the most accurate and rational dosage of the fertilizer when applied to the soil.

[0072] In addition to producing highly concentrated solutions 40 with high concentrations of macronutrients or trace elements from primary liquid manure 1, Halushko's environmentally friendly method of producing organic fertilizers, crystalline carbon, drinking water and electricity from manure allows:

[0073] - From the twice filtered and sterilized primary liquid fraction 6 to obtain and extract drinking water using a reverse osmosis process; - Dispose of the dry organic residue 25 (obtained as a by-product from the supercritical fluid extraction of the primary solid fraction 7) by converting it to pyrolysis gas mixture 28 and to pure crystalline carbon 29 in pyrolysis unit 27.

[0074] The method of processing and utilization of the dry organic residue 25 in a pyrolysis plant 27 is preferable (compared to processing by anaerobic digestion, for example in a biogas plant) because this method is more environmentally friendly, because it results in the formation and release of carbon in a solid state in the form of pure crystalline carbon 29 rather than in a gaseous state. The resulting pure crystalline carbon 29 has technical characteristics of high quality, without impurities. This is achieved due to the fact that from the primary solid fraction 7, as a result of the previously realized supercritical fluid extraction, all impurities present in the biomass of the primary liquid manure 1 were removed.

[0075] The resulting potable water 17 may be used for any of the beneficial uses characteristic of potable water applications.

[0076] The resulting pyrolysis gas mixture 28, may be further utilized to generate, for example, electricity 44, or for other purposes.

[0077] The resulting pure crystalline carbon 29 may be used for any of the useful purposes characteristic of its application.

[0078] The originality of the proposed method lies in the type and number of technological processes, in a certain sequence and conditions of these processes, in the possibility of simultaneous or sequential processing of primary liquid 6 and solid 7 fractions of primary liquid manure 1, in the subsequent mixing of the extracted organic components 31 and salt solution 18 with ethanol 38 into a complex mixture 22, and separation from this created complex mixture 22 of highly concentrated solutions 40 with high concentrations of macronutrients.

[0079] The process described herein may utilize commercially available equipment that is used in a variety of industries. The particular equipment specified herein is not exclusive or mandatory for the implementation of the method, and it is apparent to those skilled in the art that any other equivalent equipment that performs the functions of each of the steps of the process steps proposed in the method may be used to implement the invention.

[0080] The proposed technology allows to create a product (highly concentrated solutions 40 with high concentrations of macronutrients or trace elements) with complete decarbonization and absence of any other negative impact on the environment. The method enables real progress towards net zero carbon, methane and other greenhouse gases and reduced environmental impact, and economic growth. The technology also increases the efficiency of creating and using highly concentrated organic fertilizers in agriculture, and further food production, while improving the protection of soil, air and water quality, biodiversity and the environment for animals.

[0128] Halushko's environmentally friendly method of producing organic fertilizer, crystalline carbon, drinking water and electricity from manure initially involves collecting and transporting primary liquid manure 1 (or "primary manure biomass") to storage tank 2. By the term "primary liquid manure 1 " is meant: pet manure or poultry droppings, or a mixture of pet manure and / or poultry droppings, as well as a mixture of manure and / or droppings with other substances of biological origin that are produced by pet animals and / or poultry, such as urine and other. In most cases, the accumulated primary liquid manure 1 typically has a moisture content of between 75% and 95%.

[0129] In the accumulation tank 2, primary liquid manure 1 is mixed with the help of mixing device 3. The mixed primary liquid manure 1 from accumulation tank 2 is transported (pumped) by pump 4 to separation device 5 (hereinafter - separator 5). Using the separation device 5, the primary liquid manure 1 is separated (separated) into two fractions - primary liquid fraction 6 and primary solid fraction 7. At the same time, the moisture content of the primary solid fraction 7 is also reduced to the level of moisture content from 55% to 65%. Thus, as a result of separation, separation of primary liquid manure 1 into two fractions and primary moisture reduction are carried out simultaneously.

[0130] The two separated fractions (primary liquid fraction 6 and primary solid fraction 7) are then processed and treated independently of each other (either simultaneously or non- simultaneously) using different processes and equipment.

[0131] The separated primary solid fraction 7 from the separation device 5 is transported to the screw press 8 and screw extruder 9. The screw press 8 is used to remove moisture from the primary solid fraction 7. During the compression process, the temperature of the primary solid fraction 7 rises to 80-90 C as a result of compression friction0. The screw extruder 9 is also used to compress and extrude the primary solid fraction 7. During the compression process, the compression and extrusion friction also causes the temperature of the primary solid fraction 7 to rise to 80-90 C°. Accordingly, the compression and extrusion processes result in additional separation of the primary liquid fraction 6 from the primary solid fraction 7, and the temperature rise from the primary solid fraction 7 results in partial vaporization of the liquid. Thus, by means of compression and extrusion processes, secondary reduction of moisture content of the primary solid fraction 7 to a moisture content of 5 - 10% is realized.

[0132] In certain embodiments of the invention, after the secondary moisture reduction of the primary solid fraction 7, additional drying is carried out with respect to the primary solid fraction 7, for example but not limited to drum drying apparatus.

[0133] Processing and separation of the primary liquid fraction 6.

[0134] The separated primary liquid fraction 6 from the separation device 5, the screw press 8 and the screw extruder 9 is transported via pipelines to the primary filtration section 10, which contains at least one primary filtration device 11. In certain cases, the primary filtration section 10 may contain more than one primary filtration device 11. The single primary filtration device 11 may include, but is not limited to, a disk filter with automatic flushing. Multiple primary filtration devices 11 may include, but are not limited to, multiple auto-wash disk filters installed in series with varying degrees of filtration. After an earlier separation process, the primary liquid fraction 6 may contain solid mechanical impurities 30 as small as 0.25 mm. In the primary filtration section 10, primary filtration of the primary liquid fraction 6 from the solid mechanical impurities 30 up to 5 pm (i.e., which are larger than 5 pm in size) is performed. As a result of primary filtration, and after washing of the filtration devices 11 (disk filters with automatic washing), the solid mechanical impurities 30 up to 5 pm in size are separated from the primary liquid fraction 6 and transported to the accumulation tank 2 of the primary liquid manure 1.

[0135] The pre-filtered primary liquid fraction 6 (having a solid mechanical impurity size of 30 to 5 pm) is transported to the sterilization and cooling section 12, where the filtered primary liquid fraction 6 is sterilized at a temperature of 120 to 180 °C (sterilization time of 2 to 10 sec), for example, using one or more sterilization devices 13.1 in the form of plate heat exchangers.

[0136] Next, the filtered and sterilized primary liquid fraction 6 is cooled to a temperature of 20-25 °C at a temperature of - 40 to - 60 °C (cooling time of 2 - 10 sec), for example, using one or more cooling devices 13.2 in the form of plate heat exchangers.

[0137] In various individual embodiments of the method, other and devices other than plate heat exchangers may be used as sterilization devices 3.1 and cooling devices 13.2.

[0138] After sterilization and cooling, the primary liquid fraction 6 is transported to an ultrafiltration section 14, where ultrafiltration of the sterilized cooled primary liquid fraction 6 is carried out, namely filtering the primary liquid fraction 6 from solid mechanical impurities 30 up to 1 pm in size. The ultrafiltration is carried out using an ultrafiltration device 15, such as, but not limited to, a silicon carbide membrane device. In various individual embodiments of the method, different degrees of ultrafiltration may be applied at the ultrafiltration site 14, namely:

[0139] - minimum ultrafiltration from solid mechanical impurities 30 up to 1 pm in size;

[0140] - maximum ultrafiltration with partial removal of salts, fats, oils, other substances from the primary liquid fraction 6.

[0141] When implementing the proposed method, it is preferable to use a minimum degree of ultrafiltration with separation of solid mechanical impurities 30 up to 1 pm in size from the primary liquid fraction 6. Such a minimum degree of ultrafiltration provides effective safety of operation of the osmotic membranes, which leads to a significant increase in their service life. By using a minimum degree of ultrafiltration, it is possible to easily and efficiently recondition the ultrafiltration devices 15 by backwashing, for example with acid and / or alkali, thus maximizing the effective service life of these ultrafiltration devices 15.

[0142] As a result of ultrafiltration, the solid mechanical impurities 30 up to 1 pm in size separated from the primary liquid fraction 6 are transported to the accumulation tank 2 of the primary liquid manure 1. All solid mechanical impurities 30 filtered out of the primary liquid fraction 6 up to 5 pm and up to 1 pm in size are mixed with the incoming primary liquid manure 1 in the storage tank 2, and further continue to be processed cyclically in such a way that there is no overaccumulation of unprocessed solid mechanical impurities 30 in the storage tank 2.

[0143] The primary filtration devices 11 and the ultrafiltration devices 15 are washed, and as a result of washing, any solid mechanical impurities 30 remaining after the two filtration steps are transported to the accumulation tank 2 of the primary liquid manure 1.

[0144] After the ultrafiltration process, the previously sterilized and twice filtered primary liquid fraction 6 is transported to the reverse osmosis unit 16, where the reverse osmosis process is carried out. As a result of the reverse osmosis process, the primary liquid fraction 6 is separated into pure drinking water 17 and salt concentrate 18 in the quantitative ratio of drinking water 17 from 75% to 90%, salt concentrate 18 from 25% to 10%.

[0145] The resulting potable water 17 is transported (withdrawn) from the organic fertilizer production system to the water mains and / or storage tanks 2.

[0146] The salt concentrate 18 is transported to a mixing vessel 34 for mixing with ethanol 38 and with an organic component extract 31 obtained from the primary solid fraction 7.

[0147] Processes and treatment with respect to the primary solid fraction 7.

[0148] After secondary moisture reduction to 5-10%, the primary solid fraction 7 is transported to a grinding section 32 where, using one or more grinding devices 33, the maximally dewatered primary solid fraction 7 is ground to a particle size of 1.5 mm or less.

[0149] Further, the maximally dewatered and crushed primary solid fraction 7 is 'transported to a supercritical fluid extraction device 21, where, as a result of contacting the dewatered and crushed primary solid fraction 7 with a solvent in the form of a liquid gas (e.g., but not limited to CO2) which is in a supercritical state at a pressure of up to 100 to 600 Atm, at a temperature of from 40 to 90 °C, an extraction time of from 2.5 to 4 hours, 100% of all organic components (salts, oils, fats and others) contained in the organic particles of the crushed primary solid fraction 7 are extracted from the particles of the crushed primary solid fraction 7. Thus, as a result of the supercritical fluid extraction process from the crushed primary solid fraction 7, the following is formed: organic components extract 31 and dry organic residue 25.

[0150] In various individual embodiments of the method, liquid gases CO2 (carbon dioxide), ethane, ethylene, propane, SF6 (sulfur hexafluoride), and the like may be used as the solvent. In order to reduce time and energy costs, co-solvents in the form of ethanol, methanol and the like may be used in carrying out the supercritical fluid extraction process, in certain embodiments of the invention.

[0151] Mixing the organic component extract 31 and salt concentrate 18 with ethanol 38.

[0152] The organic component extract 31 of the organic components extracted from the crushed primary solid fraction 7, salt concentrate 18 (extracted from the primary liquid fraction 6), and ethanol 38 (from the ethanol tank 20) are transported to a mixing vessel 34. In the mixing vessel 34, the components are mixed in a ratio of 1 :10 to 1 :15 (where "1 " is a mixture of salt concentrate 18 and organic component extract 31, and "10-15" is ethanol 38). The exact value of said ratio depends on the amount of water in the salt concentrate 18. Thus, a complex mixture 22 of ethanol 38, water, salts and organic components extracted from the primary solid fraction 7 is created in the mixing vessel 34.

[0153] Separation of a complex mixture 22.

[0154] The resulting complex mixture 22 is then transported to a separation section 35 of the complex mixture 22 into individual substances. At the separation section 35, devices for separating complex mixtures into individual substances / components are used. Such devices may be, for example, but not limited to, a high-performance liquid chromatography device 23 and a vacuum evaporation device 24. In the high-performance liquid chromatography device 23, the high-performance liquid chromatography processes result in the separation of the complex mixture 22 into individual substances that contain at least nitrogen, phosphorus, potassium in various compounds, such as salts, and including various trace elements. Such compounds may be, for example, solutions 36 of various salts in ethanol 38 and water, containing macronutrients such as N, P, K, Ca, Mg, S, trace elements Si, Cu, Zn, Fe, Mn, Mo, Se, V and heavy metals, which are separately transported from the high-performance liquid chromatography device 23 into separate containers 37.

[0155] Extraction of ethanol and water from separate solutions 36.

[0156] After separating the complex mixture 22 into individual solutions 36, all of these solutions 36 are transported (e.g., using pumps) from individual containers 37 to a vacuum evaporation device 24. In certain embodiments of the invention, but not limited to, a falling film vacuum evaporator may be used as the vacuum evaporation device 24. The vacuum evaporation process involves complete (100% - percent) extraction of the recovered ethanol 39 from each solution 36 and partial removal of water. The recovered ethanol 39 is returned (transported) to the ethanol tank 20. The extracted water 43 is transported to the reverse osmosis unit 16. All of the above processes and actions result in the formation of various highly concentrated solutions 40 with high concentrations of the macronutrients N, P, K, Ca, Mg, S, or with high concentrations of the trace elements Si, Cu, Zn, Fe, Mn, Mo, Se, V, but not limited thereto.

[0157] The resulting highly concentrated solutions 40 with high concentrations of macronutrients or trace elements are transported to separate containers 41, and these substances can be used as independent (separate) mono-fertilizers or as constituent ingredients for complex fertilizers for agricultural crops. The resulting highly concentrated solutions 40 with high concentrations of macronutrients or micronutrients can be used to make water-soluble crystals (which are used on drip irrigation for growing organic vegetables, berries and fruits) and to make granular fertilizers that are applied to the soil when crops are sown, such as, but not limited to, grain crops.

[0158] Processing of dry organic residue 25 after supercritical fluid extraction of the crushed primary solid fraction 7.

[0159] The supercritical fluid extraction process produces a dry organic residue 25 with respect to the crushed primary solid fraction 7, in addition to extracted organic components (salts, oils, fats, and others).

[0160] In individual cases of implementation of the method, different ways of environmentally friendly recycling and utilization of the dry organic residue 25 may be used.

[0161] A preferred method of processing and utilizing the dry organic residue 25 includes producing from this dry organic residue 25 a pyrolysis gas mixture 28 and pure crystalline carbon 29 using a pyrolysis unit 27. The dry organic residue 25 is transported from the supercritical fluid extraction device 21 to the pyrolysis unit 27, which processes the dry organic residue 25 using known processes and actions inherent in known pyrolysis unit designs. The processing of the dry organic residue 25 by the pyrolysis unit 27 produces and releases: a pyrolysis gas mixture 28 and pure crystalline carbon 29.

[0162] The resulting pyrolysis gas mixture 28 is transported to a power generation device 26. Devices of the type of electric generators may be used as the electricity generating device 26. From the pyrolysis gas mixture 28, electricity 44 is obtained, which can be used to carry out the proposed method (without using electricity from external sources). An excess of the obtained electricity 44 may be directed to a common energy network.

[0163] In addition, the pyrolysis gas mixture 28 may be transported to the gas transportation system 42.

[0164] Another method of processing and utilizing the dry organic residue 25 includes producing methane gas from this dry organic residue 25 using a biogas plant (not shown in the drawing). The dry organic residue 25 is transported from the supercritical fluid extraction device 21 to the biogas plant, which processes the dry organic residue 25 using known processes and actions inherent in known biogas plant designs. The processing of the dry organic residue 25 in the biogas plant produces a mixture of gases (methane CH4 68%, carbon dioxide CO2 30%, hydrogen sulfide H2S 2%) and digestate. After removal of water, carbon dioxide and hydrogen sulfide from the methane, the purified methane can be sent to the gas transportation system or used for power generation by steam or gas turbines. Digestate can be accumulated and stored until needed for use as an organic fertilizer.

[0165] As a result of the process steps and a new set of process steps of the proposed method:

[0166] - highly concentrated solutions 40 with high concentrations of macronutrients or micronutrients are obtained, which are independent organic fertilizers and substances for the production of organic fertilizers;

[0167] - drinking water was obtained 17;

[0168] - maximum processing of all components of the primary liquid manure 1 of domestic animals and birds, including utilization of the dry organic residue 25 by obtaining from it a mixture of pyrolysis gases 28 (including methane), and at the same time obtaining from the dry organic residue 25 pure crystalline carbon 29 for its further use in other industries;

[0169] - the possibility of using the obtained mixture of pyrolysis gases 28 for the production of electricity 44, which fully covers the energy demand for the processing of primary liquid manure 1 when implementing the proposed method, has been achieved;

[0170] - surplus electricity 44 is directed to the general energy grid (this reduces greenhouse gas emissions).

[0171] The proposed method complies with all requirements for the operation and use of the specified equipment and substances, and complies with generally accepted safety regulations.

[0172] The application of the proposed method will also make it possible to spread the range of modern technologies for obtaining environmentally friendly highly concentrated organic fertilizers for use in agriculture.
