A new approach to the design of internally heat-integrated tray distillation columns

摘要

Internally heat integrated distillation column has received a great attention lately because of its ultimate potential for energy savings.Typical conceptual design of such columns is based on constant heat transfer duties along the column stages.This paper introduces more effective approach to conceptual design of heat integrated distillation columns based on constant available heat transfer areas.This design scenario implies changing stage heat transfer duties.The procedure has been implemented into a commercial simulation package in such a way that it allows simultaneous problem solutions.
