چکیده مقاله
The main problem is the high energy consumption in the gas sweetening process, especially in the distillation column, which makes it necessary to optimize the energy of this process A new method was used in this study for heat integration of natural gas sweetening process For this purpose, the liquid and vapor streams leave the absorption column entered the top and bottom of the distillation column, respectively The feed to the distillation column was preheated by the bottom product Liquid and vapor streams reduce hot and cold utilities of the distillation column, and feed preheating reduces the heating duty of the reboiler The recovered solvent was then precooled by sweetened gas According to the results, the proposed method reduced energy consumption by 67% Based on the results obtained from calculating the amount of CO2 emission, the amount of emission of this poisonous gas decreased by approximately 66 8% Moreover, proposed process could reduce total annual cost TAC of the basic process in the maximum value of 66 7% This reduction in TAC is due to the reduction of operating cost and capital cost by 66 77 and 66 64% respectively
