Pulsed liquid-liquid extraction

DESCRIPTION

Process of separation of the components of a liquid mixture based on differences in solubility of the components in a specific solvent.

The extraction occurs in a column that is pulsed in order to increase its effectiveness. The pulsations increase the amount of dispersion, resulting in a better separation without disturbing the column.

A user manual is provided.
