We use the Aspen HYSYS software to simulate the process of amine sweetening of natural gas with high acid gas content. We analyze the effect of the lean amine (absorbent) temperature on the acid gas content in the sweetened gas and saturated amine solution (the rich amine). We found that the optimal temperature for the regenerated amine solution (lean amine), at which the maximum sweetening of the gas is achieved with minimum amine circulation rate, is within the range 38°C-45°C.
