In order to clarify the situation in energy consuming devices in hydrocarbon plants (Olefin, butadiene and butene1), by using thermodynamic laws (1st and 2nd) and apply energy and exergy balances to all equipment's, loss rate and the amount of renewable energy for each group of equipment such as pumps, towers, heat exchangers and … were calculated and with the process changes, it was tried to utilize current energy as much as possible. Since the irreversibility’s cannot be omitted completely in processes, the rate of energy loss was reduced as much as possible by change in operation condition. Finally, the factors that influence the creation of irreversible processes have been discussed.
