Pinch technology is one of the important issues of heat transfer operation. It consists of the following four main steps: 1.data extraction; 2.pinch analysis; 3.heat exchanger network synthesis; and 4.network configuration design. This research deals with the process integration with application to energy-conserving technology in two different cold-temperature processes. They are (1) cryogenic air separation producing oxygen, nitrogen and argon; and (2) allyl chloride production via the chlorination of propylene and chlorine. AspenPlus and SuperTarget were used in this study. Firstly, the cold and hot stream data and heat exchanger T-Q (temperature versus duty) data were extracted from the AspenPlus process simulation. Secondly, the composite curve diagram and the grid diagram were produced from the SuperTarget. Finally, by using the heuristics of pinch technology, we were able to complete the design for these two case studies.
