Distillation system using waste heat

Abstract

The present disclosure relates to a distillation system using waste heat, the system comprising: a waste heat supply source which receives feedstock and separates the feedstock by a difference of boiling point, wherein waste heat is generated during separation of the feedstock; a heat-exchange unit which receives water from a water supply source and which evaporates the water by heat-exchange of the water with the waste heat supplied from the waste heat supply source; a mechanical vapor recompression module (MVR) which receives water vapor generated in the heat-exchange unit and which compresses the water vapor; and a waste water supply which supplies waste water generated in a separate process to the heat-exchange unit such that the amount of saturated water vapor which is supplied to the mechanical vapor recompression module is increased.
