TIEI Liquid liquid extraction equipment Work Principle
Liquid-liquid extraction (solvent extraction) was initially utilized in the petroleum industry beginning in the 1930’s. Liquid-liquid extraction describes a method for separating components of a solution by utilizing an unequal distribution of the components between two immiscible liquid phases. In most cases, this process is carried out by intimately mixing the two immiscible phases, allowing for the selective transfer of solute(s) from one phase to the other, then allowing the two phases to separate. Typically, one phase will be an aqueous solution, usually containing the components to be separated, and the other phase will be an organic solvent, which has a high affinity for some specific components of the solution. The process is reversible by contacting the solvent loaded with solute(s) with another immiscible phase that has a higher affinity for the solute than the organic phase. The transfer of solute from one phase into the solvent phase is referred to as extraction and the transfer of the solute from the solvent back to the second (aqueous) phase is referred to as back-extraction or stripping. The two immiscible fluids must be capable of rapidly separating after being mixed together, and this is primarily a function of the difference in densities between the two phases.

1) Mixed mass transfer process
The two-phase solutions enter into the mixing area of inside the shell from the two phase inlet ,which in a certain proportion to make the two phases mix
and disperse quickly and complete the mixing mass transfer process.
2)Two phase separation process
The mixed liquid enters the drum under the action of the vortex disc or feeder. Under the action of centrifugal force, the heavy phase liquid gradually moves away
from the center of the drum and towards the drum wall in the upward flow process; The light phase liquid with low density gradually moves away from the drum
wall and towards the center. The clarified two-phase liquid finally enters the collection chamber through their respective weir plates and flows out from the light
phase outlet to complete the two-phase separation process.
TIEI Extraction Skid-Mounted Systems
More than ten years of experience, TIEI Extraction designing and manufacture liquid-liquid extraction (LLE) / solvent extraction equipment. TIEI Extraction liquid-liquid Centrifugal Extractor are engineered to fulfill the challenging purification requirements that exist in the alternative energy, renewable chemicals, flavor, metals, petrochemical and hydrocarbons, pharmaceuticals, polymers, and specialty chemicals industries.
