Solvent extraction with methylene chloride and water separation process

by:Deyuan      2020-08-29
Using solvent extraction with methylene chloride water separation, obvious effect, simple operation, and extraction agent is easy to buy, so is the commonly used method of two-phase fluid extraction separation.

solvent extraction method is to choose the appropriate extraction agent, liquid organic phase in the materials will be transferred to extracting agent, and then through the separation of organic facies raw material liquid separation. Solvent extraction to operate via centrifugal extraction machine, separation effect is good, no entrainment, large quantity.

centrifugal extraction machine for methylene chloride and water separation process:

hybrid process: raw material liquid and extraction agent according to certain proportion respectively from two feeding tube into the drum and shell type ring gap formed between the mixed zone, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer process.

two phase separation process: mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall; Small proportion of liquid phase gradually away from the drum wall and on to the center, after clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete two phase separation process.

related case:
the needs of an enterprise for the methylene chloride and water separation, extraction column was adopted as before, but appear the phenomenon of flooding and separation of entrainment, and small capacity. I company for the customer to choose CWL50 - M experimental centrifugal extraction machine to test and separation effect significantly, can solve the problem of flooding and entrainment phenomenon, has been specified for the customer the industrialized production plan, equipment has been put into production, equipment operation stability.
