Abstract

Pinch analysis approach of the heat exchanger network in the hydrocracking unit was carried out to save the energy consumption and reduce the gas emissions simultaneously. This method based on mathematical model of the hydrocracking unit for a heat exchanger network using LINGO program to achieve the minimization of environmental impacts and the reduction of energy cost. The presented energy demands for the heat exchanger network are 20.38 MMBtu/hr and 26.52 MMBtu/hr for heating and cooling loads, respectively. The current analysis shows a huge opportunity in order to decrease energy consumption of the hydrocracking process at a minimum temperature difference of 60°F. The final results display the save of energy is about 44% for heating utility in furnace, while the save of cooling utility is around 34%. All these savings of the energy will lead to saving in the energy costs about 1,415,078 USD$/yr. Similarly, reducing the gas emissions of the hydrocracking unit from 12301.67 to 6854.77 metric tons/yr and this equivalent reducing of 44.3%.
