【Abstract】 The polyvinyl chloride(PVC) system is highly energy-consuming,therefore,it is worthy of applying the pinch technology to this system,so that a better heat-exchanger network can be proposed and the energy consumption can be reduced.This paper applies the pinch technology to analyze the flowsheet of a certain PVC system,thereafter,the bottleneck is found and an energy saving retrofit design is proposed and economically evaluated.更多还原
