Simulation of absorption tower with MDEA and DIPA and comparing its performance to absorb H2S and CO2 affect the amine temperature

Natural sour gas stream containing hydrogen and carbon dioxide. Gas separation processes, including acid gas sweetening process using chemical solvents. The study using simulation software Aspen plus absorption tower is simulated gas sweetening unit and impact of two amine MDEA and DIPA and amine temperature on mole fraction of sweet gas has been checked. Result have shown that the simulation error is less than 5 percent. Select the appropriate amine should be done due to the purpose of separation and reduce the temperature of the incoming amine also reduces the mole fraction and flow rate of methane in the output.
