Economic study and review of the refined gas heating value of refinery gas sweetening unit fern proposed solvent and aqueous solvent Sulfinol-M MDEA with Software Aspen Plus

More gas refineries are operating through the process of absorption by chemical solvent (amine) to as acid gases (Co2، H2S). Present study addresses the performance of mixture of physical and chemical solvent in Sarakhs gas treatment. Gas refinery of this area at present is operating with amine solvent (MDEA) active. This study will examine and estimate the performance of various concentrations of Sulfolane in the Sulfinol-M solvent in this gas refinery. Results show a decrease in total solvent flow rate، a 26487 kg/hr decrease in MDEA، a decrease in the energy condition of Sulfinol-M from 173000 SCMH to 220000، and a decrease in invested capital in both the solvent unit and other units using Sulfinol-M. the relative composition of the bulk solvent، Sulfinol-M، 42% wt Sulfolane and seek to form 38% wt، refined quality and calorific value of gas increases.، Which result in gaining export market and capital increases will follow.
