Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to U.S. patent application No. 63 / 402,727, filed on August 31, 2022, the disclosure of which is incorporated herein by reference in its entirety. Technical Field
[0003] The present invention relates to halogenated liquid and foam waste recovery, wherein spent halogenated liquids such as refrigerants, solvents, immersion fluids and foam wastes are recovered by physical and / or chemical processing, converted into high purity components, compositions and products, and optionally rebalanced in composition to meet AHRI_700_2019 quality requirements for reuse and recycling. Background Art
[0004] The popularization of circular economy concept and its adoption of reducing waste have caused remarkable concern.Halogenated olefins, such as hydrochloroolefins (HCO), chlorofluoroolefins (CFO), hydrofluoroolefins (HFO), hydrochlorofluoroolefins (HCFO) have been developed and are currently used to replace chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), thereby providing a heat transfer medium with lower global warming potential (GWP) and ozone depletion potential (ODP) properties that needs to be recovered.Halogenated olefins HCO, HFO and HCFO, and fluorinated ethers, such as hydrofluoroethers (HFE), fluoropolyethers (PFPE, HFPE), hydrofluoroolefin ethers (HFOE) and hydrofluorocarbons (HFCs), are collectively referred to as halogenated liquids, also can be used as solvents, blowing agents, foam generation, cleaning and dielectric fluids of electronic devices, which need to be recovered to reduce waste after use.
[0005] Therefore, there remains a need to apply the circular economy concept to all halogenated liquids and provide integrated / comprehensive systems and methods for recycling that will reduce liquid halogenated waste and foam waste, and generate high purity and quality recycled liquids and compositions that meet at least AHRI_700_2019 standards for recycling and use. Summary of the invention
[0006] The present invention relates to integrated recovery methods that process waste (e.g., used, contaminated) halogenated liquids and waste foam wastes and convert them into high-purity liquids, compositions and solids that meet industry standards for reuse and recycling. These waste halogenated liquids and foam wastes are recovered (collected) from various sources, such as systems that circulate heat transfer liquids, storage facilities, abandoned refrigerant sources, foam manufacturing facilities, foam recycling centers, etc. The physical and chemical properties of the waste liquids can be evaluated, and treatments can be selected to remove pollutants, moisture, water, acidity, gases (e.g., air), oils, particulates / solids, stabilizers, etc., and provide high-purity halogenated liquid components and mixtures / blends. For situations where the content of undissolved water in the halogenated liquid is above the saturation point, distillation or decantation can also be used. Water removal may involve the use of molecular sieves or decantation or a combination of the two. Distillation can be used to separate and / or purify liquid mixtures and liquid components of spent halogenated liquids, such as separating R-514A into vinylidene chloride (R-1130) and 1,1,1,4,4,4-hexafluorobut-2-ene (Z-1336mzz).

Generally speaking, the object to be cooled is at least partially immersed in (in direct contact with) a heat transfer fluid contained in a container. In some embodiments, the heat transfer fluid may evaporate and condense in the container. In other embodiments, no phase change may be involved.
[0060] Provided herein is an integrated method for recycling foam waste, including but not limited to closed-cell polyurethane foam. As known to those skilled in the art, foam waste is formed from a composition that generally includes one or more components capable of forming foam and a blowing agent. In some embodiments, the blowing agent compound is at least one of E-1336mzz, Z-1336mzz, E-1233zd, and Z-1224yd.
[0061] As used herein, a refrigerant is a compound or mixture (blend) of compounds used as a heat transfer fluid in a cycle wherein the fluid undergoes a phase change from liquid to gas and back to liquid.
[0062] As used herein, the terms "comprises," "including," "having," or any other variations thereof are intended to encompass non-exclusive inclusions. For example, a composition, process, method, article, or device that includes a list of elements need not be limited to only those elements, but may include other elements that are not explicitly listed or that are inherent to such composition, process, method, article, or device. In addition, unless expressly indicated to the contrary, "or" refers to an inclusive or and not an exclusive or. For example, a condition A or B satisfies one of the following conditions: A is true (or exists) and B is false (or does not exist), A is false (or does not exist) and B is true (or exists), and both A and B are true (or exist).
[0063] The transitional phrase "consisting of" excludes any unspecified elements, steps, or ingredients. If in a claim, protection is not included for materials other than those recited, except for impurities normally associated therewith. When the phrase "consisting of" appears in a clause in the body of a claim, rather than immediately following the preamble, it limits only the elements recited in that clause; other elements are not excluded from the claim as a whole.
[0064] The transitional phrase "consisting essentially of" is used to define a composition, method, or process that includes materials, steps, features, components, or elements in addition to those disclosed in the document, provided that these additionally included materials, steps, features, components, or elements do not significantly affect the basic and novel features of the claimed invention, especially the mode of action for achieving any desired result in the method of the invention. The term "consisting essentially of" is intermediate between "comprising" and "consisting of."
[0065] Where the applicant has defined an invention or a portion thereof using open-ended terms such as “comprising,” it should be readily understood that (unless otherwise indicated) the description should be interpreted as also including such inventions using the terms “consisting essentially of” or “consisting of.”
[0066] In addition, the use of "a" or "an" is used to describe elements and components described herein. This is for convenience only and to give a general sense of the scope of the invention. The description should be understood to include one or at least one, and the singular also includes the plural, unless it is obvious that there is another meaning.
[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those generally understood by those of ordinary skill in the art to which the present invention belongs. Although methods and materials similar to or equivalent to the methods and materials described herein can be used in the practice or testing of embodiments of the present invention, suitable methods and materials are described below. Unless citing a specific paragraph, all publications, patent applications, patents and other references mentioned herein are incorporated herein by reference in their entirety. If a conflict occurs, this specification and the definitions included therein shall prevail. In addition, materials, methods and examples are exemplary only and are not intended to be limiting.

[0074] In yet another embodiment, the unrecovered (waste) liquid may comprise any of the immersion cooling liquids disclosed in U.S. Patent Application Publication No. 2020 / 0178414, the disclosure of which is incorporated herein by reference in its entirety.

No. 10,287,469 B2, the disclosure of which is incorporated herein by reference in its entirety.
[0076] The amount and type of halogenated liquid to be recovered and described herein are transferred from the recovery / collection system 110, and where appropriate, the liquid is analyzed and its amount is determined in the station or system 120 to detect and measure impurities, including but not limited to NAG (non-absorbable gas), acid, solid, water and / or high boiling point residue content. Unrecovered halogenated liquids, such as refrigerants, liquid foaming agents, solvents, immersion cooling fluids, are analyzed using analytical techniques such as GC-FID, GC-TCD, GC-MS, FTIR, Goetz Bub, Karl Fischer, Byk-Garner Color and various other analytical methods to determine and optionally confirm the identity of the unrecovered halogenated liquid. Generally speaking, organic product analysis involves gas chromatography (GC / MS) or liquid chromatography.
[0077] The concentration of non-condensable gases (NCG) or non-absorbable gases (NAG) may be varied or altered to obtain a concentration of less than 1.5% by volume at 25°C according to AHRI 700, preferably less than 0.9% by volume at 25°C according to AHRI 700. NAGs typically comprise air (which typically consists of 78% nitrogen, 21% oxygen, and about 1% argon) accumulated in the gas phase of the refrigerant, where the solubility of air in the liquid phase is very low. While it may be important to reduce the total amount of NAG contained in the liquid, it is generally more desirable to reduce the oxygen-containing portion of the NAG in preference to the nitrogen portion. In certain circumstances, the oxygen-containing portion may increase the propensity of certain olefins to decompose or form undesirable polymeric materials. NCG can be detected using one of an infrared sensor, a UV sensor, a NIR sensor, an ion mobility or plasma chromatograph, gas chromatography, refractometry, mass spectrometry, a high temperature thick film sensor, a thin film field effect sensor, a pellistor sensor, a Taguchi sensor, and a quartz microbalance sensor, as disclosed in U.S. Patent 2008 / 0069177, the entire text of which is incorporated herein by reference.
[0078] The unrecovered liquid component or composition, even if provided by the customer, can be analyzed as described above to evaluate the physical and chemical properties of the unrecovered liquid composition, and the purity is checked to see how it compares to the industry standard of AHRI-700. Based on the analytical (test) results from the weighing and testing station, i.e., system 120, a first or primary purification will be performed using a distillation column (adsorption / desorption and cryogenic cooling and / or other separation technology) in system 130, and the first stage purified liquid will be re-analyzed and re-checked for purity. The first or primary purification system will optionally include a column with an absorbent / adsorbent to remove inhibitors and / or stabilizers from the unrecovered liquid composition disclosed herein. The column (not shown) can be located upstream or downstream of the distillation component of system 130. When silica gel or other molecular sieve materials are used as the medium for removing inhibitors and / or stabilizers, the unrecovered liquid can be passed through a silica gel bed, and the "partial" recovered product without inhibitors is transferred to one or more distillation columns to separate and isolate the various liquid components as appropriate. Then, if the primary purification does not provide a treated product that complies with AHRI-700, the treated product is transferred from system 130 to system 140 for further processing, including targeted purification for NAG (purge station), water (distillation / desiccant dryer), solids (filter), acidic (alkali bath), high boiling residue / chloride (distillation), and re-analyzed in a weighing and testing station, and re-checked for purity to verify purity and industry compliance in system 140. A NAG reduction station (not shown) can contact the partially recovered liquid composition with a reducing agent (such as a metal powder) that can react with oxygen or other oxidizable components of the unrecovered liquid composition. In one embodiment, the reducing agent can include iron powder. Processing at the NAG reduction station can result in a reduction in the concentration of one or more components of the partially recovered liquid composition to less than one or more predetermined thresholds.
[0079] The recovered liquid component from 130 or 140 is then mixed with additional fresh / natural / high purity liquid components in system 150 to provide a reconstituted, compositionally rebalanced and recovered liquid, such as a refrigerant, solvent, immersion coolant, foaming agent, composition, that meets the AHRI 700-19 standard in system 150. Tracers, stabilizers and conventional additives are added in system 160 and a final purity check is then performed so that the recovered and reconstituted liquid meets the AHRI 700-19 requirements. Each system 110, 120, 130, 140, 150 and 160 includes components for receiving and transferring liquid compositions between upstream and downstream systems, such as flow lines, valves, pumps, controls, etc. (not shown).
[0080] In another embodiment, NAG is separated from the refrigerant using a membrane positioned so that NAG can pass through the membrane and is removed while the refrigerant does not pass through the membrane.
[0081] exist Figure 2 In, system 200 shows a non-limiting example of a system and method for foam waste recovery. Foam waste, including but not limited to rigid polyurethane, is delivered, collected, classified and weighed in recovery system 210, and then after classification and weighing, transferred to treatment system 220, to physically reduce the size of foam waste to a suitable size by crushing or other techniques. When foam waste includes closed cells, rigid polyurethane foam, foam blowing agent and air are retained in the hole. When rigid foam is crushed, crushed or shredded, blowing agent and air will be released. The released blowing agent includes but is not limited to the combination of HFC and / or HFO components selected from HFC-134a, HFC-245fa, HFC-365mfc, HFC-227ea, HCFO1233zd (E), HCFO-1224yd (Z), HFO-1336mzz (E) and HFO-1336mzz (Z). Hydrocarbons can also be included, such as (cyclopentane, isopentane, normal pentane). Generally, the released cell gas will be composed of 50% to 99.5% by volume air with the balance being HFC and / or HFO. The concentration may vary depending on the amount of blowing agent used to create the foam, the amount lost to the atmosphere during the life of the foam, the amount of air that penetrates the foam during its life, and the amount of air introduced during the recovery and / or recycling process, and the efficiency of the foam crushing.
[0082] Since the processing zone is usually operated under reduced pressure, a vapor stream is formed and sent from system 240 or a dedicated distillation system (not shown) to one of the purification systems 130 and / or 140. Preferably, the cell gas composition will be known before processing, since recovery of the blowing agent will be a simpler approach for pure HFC or HFO / air mixtures. However, since the integrated recovery system includes a test station for identifying the components of the product to be recovered, the vapor removed during crushing can be analyzed before purification. The crushed and / or granulated foam waste from system 220 is collected and stored.
[0083] exist Figure 3In the process, the foam waste is fed (partially or completely) under vacuum into a process where the foam will be crushed and pulverized under vacuum, and the vapor stream is sent to a distillation process for liquid recovery. The solids are sent to a granulator for subsequent recycling. Once the foam is pulverized, the remaining solid portion is no longer foam, it is polyurethane solids. These solids can be recycled, pelletized or compressed and incinerated for fuel value, used as concrete filler, or can be recycled through glycolysis to chemically reduce the solids to liquid polyols, which can be used again to make another polyurethane foam.
[0084] Since the crushing process is performed under vacuum, excess air is minimized and distillation will primarily separate CO2, 1336mzzZ / E, 1233zdE, 1224ydZ and / or air. The vapor stream from the pulverizer is sent to a container containing a liquid (e.g., 1336mzzZ or 1233zdE). By bubbling the vapor through the liquid, gas absorption can capture the blowing agent, which is then sent to the distillation operation of system 130 or 140 for purification.
[0085] Figure 4 A non-limiting example of a service center 400 is shown that includes one or more systems 110, 120, 130, 140, 150 and 160 that can be connected to a mobile delivery vehicle 420 to charge with recycled refrigerant / refrigerant blend from system 410 via line 412, or to recharge with refrigerant or refrigerant blend that has been processed in system 410 via line 412, and optionally to remove waste refrigerant from vehicle 420 via line 422 for processing in system 410.

Liquid N. In step 2: the liquid components of the liquid mixture are separated via a separation method such as distillation. In step 3: the unpurified separated liquid may require further processing, such as additional distillation removal of NAG, etc. In step 4: the purified liquid components of step 4 are compared to industry quality standards and involve removal of moisture, solids, volatile impurities. In step 5: additives and / or tracer components are introduced into each purified individual component. In step 6: the separated, purified, added components can be mixed into other blends or used as pure components.
[0087] Figure 6 A service center system 600 is shown, in which a service center system such as Figure 5The system shown in FIG. 1 has a source of recovered / reblended refrigerant 610 connected to a refrigerant circuit 650 of a delivery vehicle (not shown), which generally includes, in sequence, a charging valve 612, an expansion device 614, a heat exchange 620, a compressor 630, a heat exchange 640, and flow lines 613, 615, 622, 631, and 641. The recovered / reblended refrigerant 610 is charged via a line 611 in fluid communication with the charging valve 612, which charges the refrigerant circuit 650 when opened.
[0088] One embodiment disclosed herein includes a system having a closed supply of recovered / reblended refrigerant, a refrigerant circuit including at least one charging valve and a compressor, and a transfer line capable of controllably connecting the closed supply of recovered / reblended refrigerant to the charging valve of the circuit.
