عنوان انگلیسی Modeling of the CO2 Separation Process from Acid Gas Feed into the Sulfur Recovery Unit ofAsaluyeh Phase 1 Using Membrane
چکیده انگلیسی مقاله In the sweetening process, acidic and sour gases, including CO2, are separated and transferred to the sulfur recycling unit. CO2 is one of the impurities in natural gas. In addition to its harmful effects on the environment, pipelines, and refinery equipment, it also has many benefits in the field of oil, gas, and petrochemicals. For this reason, the ability to Separation rate CO2 emissions by high-efficiency tools that are also economically viable is important. In this study, modeling this process before operation can be an important step in reducing the high cost of separation. In this research, the CO2 separation process using membranes has been modeled by MATLAB software, Then, the effect of CO2 separation on sulfur recovery rate was performed using sulfur recovery unit simulation by Promax software. As a result, the highest amount of sulfur recovery in the membrane process in Poly Ether Urethane Urea membrane at the level of 100000 m2 with a selectivity of 1.65 in which the amount of S2, S3, S4, S5, S6, S7, and S8 are 0.1897, 0.0191, 0.01615, 4.668, 291.3737, 121.5916, and 1821.651 kmol/h, respectively. In poly ether urethane urea membrane with a selectivity of 1.65, the optimal point is obtained at a pressure of 35 kPa and a flow rate of 72.613 mol/s. The optimum point in the dimethyl silicon rubber membrane is achieved at a permeability pressure of 25 kPa and a flow rate of 98.4847 mol/s.
