Technical Specifications
This last column can be used to recover the solvent for extraction or to be used separately for the distillation process.
Apparatus The apparatus consists of a liquid-liquid extraction glass column mounted on the side of the distillation column.
This unit can develop and analyze the following topics: Extract
Determine the number of transfer units
Height of the transfer unit
Calculation of mass transfer coefficient
Calculate the number of theoretical stages
Concentration trends along the column
Extraction efficiency
Mass balance
Practice on a system with 3 partially mixable components:
Distillation
