In the oil solvent extraction plant, it is very important to choose the appropriate solvent for product quality and production efficiency. Different solvents have different characteristics and application scope, so many factors need to be considered comprehensively when choosing solvents.

First of all, the solubility of the solvent should be considered. Oil contains many components, including fatty acids, glycerol, phospholipids, etc., and different solvents have different solubility for these components. Therefore, it is necessary to consider the composition and content of the product and the solubility of the solvent to these components when selecting the solvent.

Secondly, the volatility of the solvent should be considered. The volatile solvent can evaporate more quickly during the extraction process, thus improving the production efficiency. However, solvents with excessive volatility may cause potential safety hazards to the working environment and operators, so it is necessary to balance volatility and safety when selecting solvents.

In addition, the cost and availability of solvents need to be considered. Some solvents may be expensive or difficult to obtain, which will increase the production cost and affect the production plan. Therefore, when selecting solvents, we need to consider its cost and availability, as well as the cooperative relationship with suppliers.

What’s more, the environmental protection of the solvent needs to be considered. Some solvents may pollute the environment and even do harm to human health. Therefore, when selecting solvents, it is necessary to consider its impact on the environment and human health, and try to choose solvents with better environmental protection.

To sum up, oil solvent extraction plants need to comprehensively consider factors such as solubility, volatility, cost and availability, and environmental protection when selecting solvents. Only by comprehensively considering these factors and weighing them according to the actual situation can the most suitable solvent be selected, thus ensuring the product quality and production efficiency.
