Description

Technical Field

[0001] The invention belongs to the technical field of palm oil production, in particular to a demulsifying and conditioning agent for oil extraction from palm oil wastewater. Background Art

[0002] In the process of palm oil production and waste oil treatment, the emulsification of oil in water significantly affects production efficiency and product quality. In addition to optimizing reaction conditions and standing time, the introduction of appropriate agents has become an economical and effective solution to this problem. Demulsifiers are widely used as chemical additives in the fields of industry and environmental engineering. Their main function is to destroy the stability of emulsions and promote the efficient separation of oil and water. From the perspective of action mechanism, demulsifiers can be divided into positive phase demulsifiers and reverse phase demulsifiers. Positive phase demulsifiers have good oil phase solubility due to the longer hydrophobic groups in their molecular structure, which enables them to effectively destroy the interfacial film of emulsified droplets, promote the aggregation and enlargement of oil droplets, and finally achieve oil-water separation. In terms of peptization, specific components in positive phase demulsifiers can also react chemically with natural emulsifiers (such as asphalt, colloid, etc.) on the interfacial film, causing these emulsifiers to dissolve, thereby destroying the stability of the interfacial film. In addition, positive phase demulsifiers can also promote oil-water separation by reducing the tension at the oil-water interface. Reverse demulsifiers can form a charged molecular layer by adsorbing on the surface of oil droplets, triggering a repulsive effect between oil droplets, promoting the aggregation of oil droplets, and thus accelerating the oil-water separation process. In addition to enhancing the interfacial tension of the oil-water interface, reverse demulsifiers can also promote oil-water separation by neutralizing the charge on the surface of oil droplets, reacting with substances on the surface of oil droplets, or destroying the emulsified state. They can also promote the aggregation of oil droplets through flocculation to form larger oil droplets, making it easier to separate the oil droplets from the water.

[0003] However, the existing normal phase demulsifiers can only achieve the ideal separation effect when used in large quantities, and the cost is relatively high. Reverse phase demulsifiers adsorb on the surface of oil droplets to form a charged molecular layer, triggering a repulsive effect between oil droplets, promoting the aggregation of oil droplets, and thus accelerating the oil-water separation process. However, the performance of reverse phase demulsifiers may be affected when the pH value and temperature conditions change greatly, resulting in unstable separation effect. Summary of the invention

[0004] The object of the present invention is to provide a demulsifying and conditioning agent for oil extraction from palm oil wastewater in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the present invention is as follows: a demulsifying and conditioning agent for oil extraction from palm oil wastewater, the conditioning agent is composed of 90 to 99 parts by weight of polypropylene glycol, 0.3 to 9 parts by weight of oleic acid amide, and 0.3 to 5 parts by weight of high-carbon carboxylic acid;

[0006] The high carbon carboxylic acid is one of the acids from decacarboxylic acid (decanoic acid) to arachidic acid (arachidic acid).

[0007] In a preferred embodiment, the preparation method of the conditioning agent comprises the following steps:

[0008] S1: Measure a certain proportion of polypropylene glycol and ensure that its quality meets the formula requirements. As the main component of demulsifier and conditioner, polypropylene glycol has good solubility and emulsification ability, can effectively adsorb and dissolve the natural emulsifier on the oil-water interface, and destroy the stability of the emulsified system;

[0009] S2: Heat the polypropylene glycol to a certain temperature and stir it slowly. The temperature is selected based on the melting point of the selected high-carbon carboxylic acid to ensure that the high-carbon carboxylic acid can be liquefied and dispersed in the polypropylene glycol after addition, so as to avoid the high-carbon carboxylic acid from precipitating in the polypropylene glycol and affecting the performance of the demulsifier. At the same time, the stirring speed should not be too fast to avoid generating too many bubbles and affecting the subsequent steps;

[0010] S3: After the polypropylene glycol reaches the target temperature, add the weighed oleamide at one time. As a nonionic surfactant, oleamide can affect the oil-water interfacial tension, promote the aggregation and condensation of oil droplets during the demulsification and conditioning process, and help the high-carbon carboxylic acid to be stably and evenly distributed in the polypropylene glycol. After adding oleamide, continue stirring until it is completely dissolved;

[0011] S4: Stir until oleic acid amide is completely dissolved to form a homogeneous liquid. Ensure that oleic acid amide and polypropylene glycol are fully mixed to form a stable demulsifier and conditioner base solution. At this point, the base solution should be transparent or translucent without obvious particles or impurities;

[0012] S5: Add the weighed high-carbon carboxylic acid at one time. As an additive in the agent, the high-carbon carboxylic acid mainly plays a role in synergistically destroying the emulsion interface film. After adding the high-carbon carboxylic acid, the stirring rate should be increased to fully disperse it in the mixture of polypropylene glycol and oleamide;

[0013] S6: Increase the stirring rate to fully disperse the high carbon carboxylic acid in the mixture of polypropylene glycol and oleic acid amide. The stirring speed should be moderate to ensure that the high carbon carboxylic acid is fully dispersed while avoiding the generation of excessive bubbles;

[0014] S7: Emulsify for a period of time to ensure that all components are fully mixed. The emulsification time should be adjusted according to the specific formula and stirring rate to ensure that all components are fully mixed and form a stable demulsifier;

[0015] S8: Stop stirring and cool naturally to room temperature. During the cooling process, avoid severe vibration or collision to avoid affecting the performance of the demulsifier. After cooling to room temperature, the demulsifier can be packaged or used.

[0016] In a preferred embodiment, in step S1, when measuring polypropylene glycol, it should be accurately weighed according to the formula requirements and weighed in a clean and dry container to avoid the influence of moisture and impurities.

[0017] In a preferred embodiment, in step S2, the stirring speed should not be too fast to avoid generating too many bubbles and affecting the subsequent steps. The heating temperature is between 60 and 80° C., and the specific temperature can be adjusted according to the melting point of the selected high-carbon carboxylic acid. The stirring speed is between 100 and 500 rpm, and the specific speed can be adjusted according to the viscosity of the polypropylene glycol and the stirring equipment.

[0018] In a preferred embodiment, in step S3, oleamide, as a nonionic surfactant, can affect the oil-water interfacial tension, promote the aggregation and condensation of oil droplets during demulsification and conditioning, and help the high-carbon carboxylic acid to be stably and evenly distributed in polypropylene glycol. After adding oleamide, stirring should be continued until it is completely dissolved. The amount of oleamide is between 0.3 and 9 parts, and the specific ratio can be adjusted according to actual needs.

[0019] In a preferred embodiment, in step S4, the base solution should be transparent or translucent without obvious particles or impurities. The stirring time is between 20 and 40 minutes, and the specific time can be adjusted according to the dissolution rate of oleamide and the stirring equipment.

[0020] In a preferred embodiment, in step S5, after adding the high carbon carboxylic acid, the stirring rate should be increased to fully disperse it in the mixture of polypropylene glycol and oleamide. The amount of the high carbon carboxylic acid is between 0.3 and 5 parts, and the specific ratio can be adjusted according to actual needs.

[0021] In a preferred embodiment, in step S6, the stirring rate is increased to 700 rpm to fully disperse the high carbon carboxylic acid in the mixture of polypropylene glycol and oleamide. The stirring speed should be moderate to ensure that the high carbon carboxylic acid is fully dispersed and to avoid generating too many bubbles. The stirring speed is between 500 and 1000 rpm, and the specific speed can be adjusted according to the dispersion speed of the high carbon carboxylic acid and the stirring equipment.

[0022] In a preferred embodiment, in step S7, the emulsification time should be adjusted according to the specific formula and stirring rate to ensure that all components are fully mixed and uniformly formed to form a stable demulsifying and conditioning agent. The emulsification time is between 30 and 60 minutes, and the specific time can be adjusted according to the dispersion speed of the high carbon carboxylic acid and the stirring equipment.

[0023] In a preferred embodiment, in step S8, after cooling to room temperature, the demulsifying and conditioning agent can be packaged or used. Clean and dry containers should be used for packaging and sealed to avoid the influence of moisture and impurities.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, the demulsifier and conditioner product produced has good stability, will not demulsify during long-term storage, has controllable cost, can efficiently separate waste oil from palm oil production wastewater and kitchen wastewater, and the production processes of different products are similar and fast, and the formula ratio can be adjusted according to the characteristics of different wastewaters to achieve the best demulsification and conditioning effect. For wastewater with a high oil content, the amount of oleamide can be appropriately increased to improve the lipophilicity of the demulsifier and conditioner; and for wastewater with a high water content, the proportion of polypropylene glycol can be increased to enhance the hydrophilicity of the demulsifier and conditioner. In addition, the demulsifier and conditioner of the present invention is environmentally friendly during use, does not produce secondary pollution, and meets current environmental protection requirements.

[0026] 2. In the present invention, by adjusting the dosage of polypropylene glycol, oleamide and high-carbon carboxylic acid, the purpose of efficient oil-water separation is achieved while ensuring cost, stability and long-term storage without demulsification. Compared with similar products on the market, it is more efficient, has a better separation effect when the dosage is the same, and requires less medicine for the same effect.

[0045] In step S6, the stirring rate is increased to 700 rpm to fully disperse the high carbon carboxylic acid in the mixture of polypropylene glycol and oleamide. The stirring speed should be moderate to ensure that the high carbon carboxylic acid is fully dispersed and to avoid generating too many bubbles. The stirring speed is between 500 and 1000 rpm, and the specific speed can be adjusted according to the dispersion speed of the high carbon carboxylic acid and the stirring equipment.

[0048] Example 1

[0049] Measure 99.05 parts of polypropylene glycol, stir at a rate of 500 rpm, heat to 70°C, add 0.35 parts of oleamide after the temperature reaches 70°C, stir for 20 minutes to ensure that oleamide is completely dissolved and the liquid phase is uniform. Add 0.2 parts of hexadecanoic acid (palmitic acid) and 0.4 parts of octadecanoic acid (stearic acid), increase the stirring rate to 700 rpm, stir for 40 minutes until the phase is uniform, turn off the stirring, pour out the product after natural cooling and pot it.

[0050] Example 2

[0051] Measure 95 parts of polypropylene glycol, stir at a rate of 300 rpm, heat to 65°C, add 2.5 parts of oleamide after the temperature reaches 65°C, stir for 30 minutes to ensure that oleamide is completely dissolved and the liquid phase is uniform. Add 1.5 parts of capric acid and 1 part of hexadecanoic acid (palmitic acid), increase the stirring rate to 600 rpm, stir for 30 minutes until the phase is uniform, turn off the stirring, pour out the product after natural cooling and pot it.

[0052] Example 3

[0053] Measure 90 parts of polypropylene glycol, stir at 800 rpm, heat to 80°C, add 4 parts of oleamide after the temperature reaches 80°C, stir for 40 minutes to ensure that oleamide is completely dissolved and the liquid phase is uniform.

[0054] In order to further illustrate the performance of the demulsifier and conditioner prepared in the embodiment of the present invention, the following selects Example 1 and compares it with Comparative Example 1 of the same type of normal phase demulsifier available on the market to conduct effect tests.

[0055] The oil content of the wastewater from a palm oil factory in Malaysia was 1.59%. 40 mL of water sample was taken from each group and allowed to stand at 70 °C for 2 hours, then centrifuged at 3000 rpm for 30 seconds. The oil content of the surface 10 mL water sample was taken as the available oil rate. The demulsification, conditioning and oil extraction effect was determined by comparing the oil content of the middle layer water sample and the available oil rate. The final experimental results are as follows:

[0056]

[0057] As can be seen from the table, after adding Example 1, the oil content of the middle water phase decreased significantly, and the available oil rate of the surface water layer increased significantly through heating, standing and centrifugation. Compared with Comparative Example 1, the oil-water separation of Example 1 is more efficient, that is, the effect of 400ppm Comparative Example 1 is between 200ppm and 300ppm Example 1.

[0058] It can be learned from the above experimental results that: in the present invention, the demulsifier and conditioner product produced has good stability, will not demulsify during long-term storage, has controllable cost, can efficiently separate waste oil from palm oil production wastewater and kitchen wastewater, and the production process of different products is similar and fast, and the formula ratio can be adjusted according to the characteristics of different wastewaters to achieve the best demulsification and conditioning effect. For wastewater with a high oil content, the amount of oleamide can be appropriately increased to improve the lipophilicity of the demulsifier and conditioner; and for wastewater with a high water content, the proportion of polypropylene glycol can be increased to enhance the hydrophilicity of the demulsifier and conditioner. In addition, the demulsifier and conditioner of the present invention is environmentally friendly during use, does not produce secondary pollution, and meets current environmental protection requirements.

[0059] In the present invention, by adjusting the dosage of polypropylene glycol, oleamide and high-carbon carboxylic acid, the purpose of efficient oil-water separation is achieved while ensuring cost, stability and long-term storage without demulsification. Compared with similar products on the market, it is more efficient, has a better separation effect when the dosage is the same, and requires less medicine for the same effect.
