Simulation works for comparing removal capabilities of acid gases contained in natural gas and among several aqueous amine absorbents using commercial process simulator PROMAX(BR&E Co.) were carried out. Amine aqueous solution used in this study were 30wt% MEA, 30wt% DEA, 50 wt% MDEA, and 50wt% MDEA with 3wt% Piperazine as additive. We obtained the simulated results that while MEA aqueous solution is relatively capable of more CO2 gas, but DEA, MDEA, and MDEA aqueous solutions with piperazine as additive is capable of more H2S gas. Also, we found that 30wt% MDA aqueous solution is smallest circulate rate of lean amine solution, and 50wt% MDEA aqueous solution with 3wt% piperazine as additive is smallest heat duty in stripping unit. 50wt% MDEA aqueous solution with 3wt% Piperazine as additive found less amine circulation rate than 50wt% MDEA due to the introduction of additive. Meanwhile, CO2 Removal Capabilities Between Rectisol, Selexol and Purisol Process for DME synthesis and Separation Process were compared. Total CO2 removal process in order to process simulation process Rectisol was used Two model Approach expression and Selexol, Purisol was used fair expression of the SRK Polar model. Simulation results that Selexol, Purisol do not have regenerator than the initial equipment investment and know that the operation was less costly.
