原料液濃縮システム

Japanese Patent JP7233530

B2

Provided is a system that can prevent or reduce adhesion of a raw material component to a membrane surface and increase the recovery rate of the raw material component after concentration. A raw material liquid concentration system for a medicine production process is provided with: a forward osmosis membrane unit having a forward osmosis membrane, and a raw material liquid side space and an inductive solution side space which are separated from each other by the forward osmosis membrane; a raw material liquid channel for supplying, to the raw material liquid side space, a raw material liquid containing a solvent and a solute; an inductive solution channel for supplying, to the inductive solution side space, an inductive solution containing an inductive material; a concentrated liquid channel for removing a concentrated raw material liquid from the forward osmosis membrane unit; and a diluted inductive solution channel for removing a diluted inductive solution from the forward osmosis membrane unit. The forward osmosis membrane produces the concentrated raw material liquid and the diluted inductive solution by moving the solvent in the raw material liquid into the inductive solution and by moving the inductive material in the inductive solution into the raw material liquid.
