Rational Energy Recovery from the Condensed Steam as a Component of HEN Retrofit

The paper is concerned with retrofitting a heat exchanger network (HEN) using a Pinch-based method (PT) and simultaneously minimizing energy losses caused by the expansion of steam condensate. The disadvantages of conventional multi-stage condensate expansion are identified, and the application of...
