Methanol from dichloroethane operation process and equipment selection

by:Deyuan      2020-09-05
When methanol and ethylene dichloride separation using solvent extraction effect is remarkable, is now more commonly used separation method. Solvent extraction is widely used because of solvent extraction advantage:

1, the solvent extraction method is simple and convenient operation, good separation effect;

2, solvent price was cheap, can be recycled, save cost.

solvent extraction operation can choose has a variety of equipment, such as extraction, extraction tower, reaction kettle, centrifugal extraction machine, etc. , so how to choose the suitable extraction separation equipment, need to undertake choosing according to specific material system, but with a large amount of data, centrifugal extraction machine of extraction separation effect is good, can greatly save customers comprehensive cost of investment.

centrifugal extraction machine compared with other extraction equipment, the working principle of the distinction that having essence. Centrifugal extraction machine is a mixture of rely on centrifugal force the two phase fluid fast separation, specific work process is:

according to two phase solution 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. Complete mixing and mass transfer 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.

the customer in the separation of methanol and ethylene dichloride, need to be done according to the specific processing equipment selection, at the same time, through the selection of process equipment series, particular case counseling online customer service for details.
