摘要: Abstract To perform the continuous simulation of CO2/H2 separation by hydrate-based gas (HBGS) process, a new multi-phase isothermal flash calculation method, which is more simple, accurate, and easier to converge, has been proposed. In this method an “infinitesimal elements” theory developed avoid non-convergence caused improper initial value. Following, relationship among main thermodynamic parameters system discussed under equilibrium stage. Then with calculation, optimization HBGS for 40% CO2 + 60% H2 at 277 K are performed. The results show obtain mixture CO2 than 90%, three stages needed. split fractions 28.74%, 13.99% 48.19% in sequence. factors 29.88, 13.65 41.57, respectively. three-stage two-stage hybrid hydrate-membrane processes It declares that may be suitable enrichment from CO2/H2.
