Energy conservation and optimization is an important method in chemical process industry. From industrial industry facts, the calculation of minimum heating and cooling requirements reveal significant energy savings. This studyaddressesthedetermination of optimum process to process heat exchange at minimumHeat Recovery Approach Temperature (HRAT) for an existing heat exchanger network. The study is applied according to the Pinch Technology concepts on the most common heat exchanger network (HEN) which isthe crude preheat train unit. Minimum heating and cooling requirements were determined for such HEN after excessive heat load shifting using five utility paths combination options at different HRAT values.A minimum HRATcorresponds to the optimum total cost has been determined for each paths combination and found to range between 8oC to 14oC.Then a complete economical analysis was conducted for each option to decide and pick up the most optimum. Such economical evaluation involved the determination of capital investment for the minor retrofit of HEN and the expected energy savings. From investment and savings, the payback period has also been calculated for each option and found to range between 0.5 to2.5 years. Two options were found to be the best but having critical argument and trade-offto choose the optimum from them. Both of them are showing great energy savings and moderate investment with little time of payback spam. However, the optimum readings of one of these options was at 8oCHRAT which considered to be small and might restrict the process of heat transfer. Based on this study, it is recommended to consider HEN streams and exchangers pressure dropfor further study.
