The images below show a simulation that solves a problem associated with the separation of carbon dioxide and methane by absorption of carbon dioxide into propylene carbonate. It uses a packed column operating at 60 °C and 60.1 atm with an inlet gas stream of 20 mol% carbon dioxide, 80 mol% methane, and 17,500 kmol/hr. The inlet solvent flow is 2,000 kmol/hr, and the column has 10 stages with a random packing of ceramic Raschig rings (25 mm) and a section packed height of 0.3 m . The goal of this simulation is to find the composition of the outlet stream, which, according to the stream results, contains a mole fraction of 19.4% carbon dioxide, which isn't a significant separation. This shows that the presented method of carbon dioxide-methane separation isn't sufficient and should be improved or adjusted.
