Pinch technology has been employed as an important tool for the heat integration of petroleum refining processes. The thermal integration of heat pumping system is done by this technology. A heat pump is a system that takes low level heat from a source and delivers it to a sink where higher heat load and temperature levels are required. Heat pump integration in separation columns operates between the condenser as heat source and the reboiler as a heat sink. Therefore, it operates by extracting an amount of heat from a source with a relatively low temperature and delivering a larger amount of heat to a sink with a higher temperature by consuming high quality energy. In this study, the proper heat integration feasibility of a heat pump is done in the LPG process of Tehran oil refinery, which resulted in a $ 144,000 annual savings in energy cost.
