Although distillation is one of the most energy consumer processes, it is common in industrial units. Therefore, saving of energy in that is attractive for researchers. In this work, a thermodynamic analysis based on internal heat integration for distillation column with the aim of applying inter–reboiler and inter–cooler is presented. In this method, the exergy concept is employed to judge the quality of energy as well as a new driving force in order to thermal load and side exchanger position optimization. Also, this method makes it possible to evaluate energy saving. The simulation results of Debutanizer distillation column by using of proposed method show that many problems i.e.: temperature changes and errors in thermal load after replacing inter–reboiler and inter–cooler that have already occurred, did not happen in this method. Furthermore, using of this method leads to significant savings in required energy of column.
