Abstract

Energy is the most important driving force for the social and economical development of a country. Nowadays, especially energy-sensitive industries such as refining and petrochemical industries are targeting to recover maximum amount of energy by applying to process integration. The energy consumed in industrial processes is typically used for heating and cooling purposes. Efficient design of heating and cooling systems in an industry is therefore vital. In the present energy crisis scenario all over the world, the purpose of any process design is to maximize the process to process heat recovery and to minimize the utility requirements. An appropriate HEN is required for the comparison of maximum energy recovery or minimum energy requirement (MER).

In this study, the exergetic evaluation of heat exchanger network (HEN) in a raw petroleum cracking unit is to be performed. The pinch analysis and second law insight analysis are applied on the existing HEN of the raw petroleum cracking unit. Then the exergy loss and exergetic efficiencies of networks are calculated. It is seen that exergetic loss of second law insight HEN is lower than the pinch HEN.
