Process

A hybrid system of distillation and pervaporation processes has been sucessfully developed, being able to perform the investigation of process to effectively and economically separate a wide range of mixtures as well as a mixtue having a large concentration range to be concentrated.    

The distillation system has a flexibility in process operation: the distillation tower is equipped with an agitation device which can agitate the vapor/liquid mixture along with the length of the tower, resulting in effective contact between them. Thus, the number of distillation stages can be determined, depending on the agitation speed, theoretically up to infinite stages. The tower is also equipped with a heating system to give temperature profile along the tower height, and the reboiler is heated indirectly by circulation of a heating medium of silicone. In addition, vacuum distillation will also be able to be carried out by the vacuum pump installed.

The pervaporation (vapor permeation) unit enable the distillate from distillation tower to be highly purified: The pervaporation unit is installed to the top of the distillation tower from which a distillate is fed into the pervaporation membrane module and purfied to high degree by the pervpaoration process.
