摘要：UniSim Design software was used to simulate the H_2 recovery process from purge gas of gas to liquid plant. In different processes with different membrane modules namely polyimide(PI)with one stage recovery process and polysulfone(PSf)with one stage and two stage recovery processes, effect of permeation pressure on mole fraction of H_2 product, H_2 recovery rate and economic benefit were discussed. The simulation results showed that in conditions of purge gas pressure(G) 3.0 MPa, temperature 45 ℃ and feed flow rate 1.33×10~5 m~3/h, choosing PI membrane module with one stage recovery process can obtain higher economic benefit than choosing PSf membrane module when mole fraction of H_2 product is not more than 94.0%. When mole fraction of H_2 product is in the range of 90.0%-94.0%, economic benefit is the highest if permeation pressure is maintained in the range of 100-150 kPa(G).
