Introduction:This process employs a full vacuum evaporation process, which improves the quality of crude oil and significantly reduces steam and solvent consumption, thus greatly reducing production costs.Added Benefits:Compared to atmospheric evaporation, the vacuum evaporation process results in lower peroxide values and lighter color in the crude oil, and it also saves energy. Actual calculations show that vacuum evaporation saves about 133kg of steam per ton of raw material, 900kg of cooling water, and reduces solvent consumption by 1-1.5kg, equivalent to a cost savings of 33 RMB per ton of material. For a 200t/d extraction plant, the cost savings can be nearly 2.4 million RMB a year.Advantages:(1) Energy Saving: The secondary steam from the Hongyang steaming and de-solventing machine is used as the heat source for the first evaporation, and the negative pressure reduces the evaporation temperature, reducing the steam and circulating water usage throughout the production line. After implementing vacuum evaporation, the quality of the oil product is improved, water washing and degumming is easier, and the amount of bleaching clay used is reduced. The solvent consumption in the workshop also decreases due to negative pressure operation.(2) Improved Quality of Crude Oil: The operating temperature is lower than atmospheric pressure, resulting in smaller peroxide values, lighter color, and usually a residual solvent content of less than 0.02%, thus improving the quality of the crude oil.(3) Reduced Condensation Area: The condensation system has less burden, so the condensation area can be reduced by 40% compared to atmospheric evaporation.(4) Enhanced Workshop Safety: The entire system operates under a slight negative pressure environment, reducing the leakage of solvent and improving the safety of the extraction workshop.(5) Improved System Stability: An automatic control system is set up, with key parameters of the system controlled by automatic instruments, reducing the labor intensity of workers and enhancing the stability of the system operation.(6) Extended Equipment Life: Poor quality oil from atmospheric evaporation leads to more protein and mucilage buildup, which can clog the evaporation tubes over time, affecting performance and shortening the equipment's lifespan.Process Flow:The pretreatment material is conveyed by a scraper conveyor into the extraction workshop and falls into the flat rotary extractor through a sealed auger. The material is then sprayed with solvent or mixed oil for extraction. After draining, the wet meal falls into the meal hopper and is conveyed through the scraper conveyor and sealed auger into the steaming and de-solventing machine. After de-solventing and drying, it is transported to the finished meal warehouse. The concentrated mixed oil filtered by the Hongyang extractor flows into the mixed oil tank, then enters a long tube evaporator to separate solvent steam. It then flows into a second long tube evaporator for further separation of solvent steam. After separation, it flows into the stripping tower to remove residual solvent. The crude oil is then transferred to the crude oil tank and sent to the refining workshop. The solvent steam from the steaming and de-solventing machine is used as the heat source in the long tube evaporator, and a vacuum pump is used to create a vacuum, operating the entire mixed oil evaporation system under a vacuum state. The solvent steam from the long tube evaporator and the second long tube evaporator, the stripping tower, the flat rotary extractor, and the steaming and de-solventing machine is introduced into the condenser for condensation. The condensed liquid flows into the separator for water separation, and the separated solvent returns to the solvent circulation warehouse. The wastewater from the separator and the solvent circulation warehouse flows into the boiling water tank for boiling and then to the water seal pool. The free gases from the top of each device are collected into the condenser for condensation, and the non-condensed gas enters the absorption tower for further solvent capture.Main Specifications:daily capacity: 80ton, 100ton, 150ton, 200ton, 300ton, 450ton, 600ton, 800ton.Main Equipment:rotary extractor, desolventizer, condenser, long tube evaporator, stripping tower, absorption tower, vacuum pump, scraper conveyor, sealed conveyor, etc.

Product Introduction

Introduction:

This process employs a full vacuum evaporation process, which improves the quality of crude oil and significantly reduces steam and solvent consumption, thus greatly reducing production costs.

Added Benefits:

Compared to atmospheric evaporation, the vacuum evaporation process results in lower peroxide values and lighter color in the crude oil, and it also saves energy. Actual calculations show that vacuum evaporation saves about 133kg of steam per ton of raw material, 900kg of cooling water, and reduces solvent consumption by 1-1.5kg, equivalent to a cost savings of 33 RMB per ton of material. For a 200t/d extraction plant, the cost savings can be nearly 2.4 million RMB a year.

Advantages:

(1) Energy Saving: The secondary steam from the Hongyang steaming and de-solventing machine is used as the heat source for the first evaporation, and the negative pressure reduces the evaporation temperature, reducing the steam and circulating water usage throughout the production line. After implementing vacuum evaporation, the quality of the oil product is improved, water washing and degumming is easier, and the amount of bleaching clay used is reduced. The solvent consumption in the workshop also decreases due to negative pressure operation.

(2) Improved Quality of Crude Oil: The operating temperature is lower than atmospheric pressure, resulting in smaller peroxide values, lighter color, and usually a residual solvent content of less than 0.02%, thus improving the quality of the crude oil.

(3) Reduced Condensation Area: The condensation system has less burden, so the condensation area can be reduced by 40% compared to atmospheric evaporation.

(4) Enhanced Workshop Safety: The entire system operates under a slight negative pressure environment, reducing the leakage of solvent and improving the safety of the extraction workshop.

(5) Improved System Stability: An automatic control system is set up, with key parameters of the system controlled by automatic instruments, reducing the labor intensity of workers and enhancing the stability of the system operation.

(6) Extended Equipment Life: Poor quality oil from atmospheric evaporation leads to more protein and mucilage buildup, which can clog the evaporation tubes over time, affecting performance and shortening the equipment's lifespan.

Process Flow:

The pretreatment material is conveyed by a scraper conveyor into the extraction workshop and falls into the flat rotary extractor through a sealed auger. The material is then sprayed with solvent or mixed oil for extraction. After draining, the wet meal falls into the meal hopper and is conveyed through the scraper conveyor and sealed auger into the steaming and de-solventing machine. After de-solventing and drying, it is transported to the finished meal warehouse. The concentrated mixed oil filtered by the Hongyang extractor flows into the mixed oil tank, then enters a long tube evaporator to separate solvent steam. It then flows into a second long tube evaporator for further separation of solvent steam. After separation, it flows into the stripping tower to remove residual solvent. The crude oil is then transferred to the crude oil tank and sent to the refining workshop. The solvent steam from the steaming and de-solventing machine is used as the heat source in the long tube evaporator, and a vacuum pump is used to create a vacuum, operating the entire mixed oil evaporation system under a vacuum state. The solvent steam from the long tube evaporator and the second long tube evaporator, the stripping tower, the flat rotary extractor, and the steaming and de-solventing machine is introduced into the condenser for condensation. The condensed liquid flows into the separator for water separation, and the separated solvent returns to the solvent circulation warehouse. The wastewater from the separator and the solvent circulation warehouse flows into the boiling water tank for boiling and then to the water seal pool. The free gases from the top of each device are collected into the condenser for condensation, and the non-condensed gas enters the absorption tower for further solvent capture.
