Solvent extraction linolenic acid degreasing effect and equipment selection

by:Deyuan      2020-08-30
Linolenic acid degrease is pharmaceutical biotech firms often do the operation of the project, and for linolenic acid degrease, using solvent extraction effect is remarkable. Solvent extraction method is adopted and the raw liquid are immiscible extraction agent, extraction solvent and raw material liquid injection machine, centrifugal extraction by mixing, liquid organic phase in the materials will be transferred to extracting agent, and then a quick separation process.

linolenic acid degrease is usually carried out at room temperature, according to the customer's specific requirements and feeding system, customers can choose two levels of countercurrent extraction, the early stage of the test will be carried out in experiment, according to the experimental data for industrial equipment selection.

specific operation process:

linolenic acid and extracting 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. 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.



centrifugal extraction machine performance characteristics:

1, low power consumption: on the premise of guarantee the extraction rate and the separation efficiency, low power consumption of a new type centrifugal extraction machine, capacity is bigger;

2, no vulnerable parts: new centrifugal extraction machine adopts hanging structure, cancel the machine seal at the bottom of the traditional models, so as to thoroughly solve the traditional models, leakage at the bottom of the machine, the seal;

3, simple structure, stable: at the beginning of the new type of centrifugal extraction machine from the design of the body is simplified and improve machining precision, make the operation more simple, run more smoothly.

4, choice of materials: for acid containing chlorine ion system, our company invested heavily to develop high polymer composite material, not only satisfy the strength of equipment required, but also solve the corrosion problem.
