Abstract：Based on actual Rectisol process, its simulation for purifying the reformed gas of F-T synthesis tail gas using Aspen Plus software was carried out, some key parameters including flow rate of purified gas and volume fraction of each component were obtained, and the results calculated from Aspen Plus were in consistent with the actual data. The related parameters were optimized using sensitivity analysis method. At last, the capacity of adsorption tower could be improved by 8.84% at the existing operating conditions. The suitable temperature range of methanol was from -44 to -41℃, and the flow rate of methanol to the adsorption tower was decreased by 11.96%, at the same time, the distillation rate of thermal regeneration tower was decreased by 9.55%, when the load of reformed gas was steady and CO2 content in the purified gas was controlled by 0.5%(j), the energy consumption of the purified process was reduced by 9.43% under the optimized conditions.
