Description

Technical Field

[0002] Intermediates refer to a class of substances generated in the middle of various chemical reactions. They are important raw materials in the fields of chemical industry, medicine, pesticide, etc. The production of intermediates usually involves multi-stage chemical reactions and extraction processes. Continuous extraction equipment is required to achieve an efficient and continuous production process. Chemical intermediates need to be extracted and purified during use. Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that uses the different solubility of components in the system in the solvent to separate the mixture. It is a method of transferring solute substances from one solvent to another solvent by using the different solubility or distribution coefficient of substances in two immiscible solvents.

Usually, multiple extraction tanks are set in series to achieve continuous extraction, which greatly improves efficiency, but correspondingly, multiple extraction tanks need to be used, which increases equipment cost and space occupancy.
