The feasibility of using N>-formylmorpholine as solvent for high concentration acid gas treatment was studied. PC-SAFT equation was used to fit the parameters of acid gas CO2 and H2S in the physical solvent of N-formylmorpholine,and compared with polyethylene glycol dimethyl ether solvent. On this basis,using the general chemical process simulation software,designed to use the above mentioned two solvents to extract high concentration of H2S in the acid gas and simply compare the main operating energy consumption of the two solvents. On the basis of the results of flow simulation,N-formylmorpholine solvent has some advantages in the application of high acid gas separation process,and has industrial application value.
