The separation of propane-propylene mixtures is one of great industrial importance. It is also one of the most difficult and costly to achieve. In this work, the feasibility of using sorbents based on kinetic (due to differences in diffusion rates) or steric (due to size exclusion) effect for gas-phase separation of propane-propylene was determined. Equilibrium isotherms and uptake curves were measured...
A pressure-swing adsorption (PSA) simulation study was performed for the separation of a mixture of 95% O2 and 5% Ar using a molecular sieve carbon (MSC) as the adsorbent. Two PSA cycles have been outlined to maximize the recovery of either argon or oxygen as a high purity product. The effect of cycle parameters such as cocurrent depressurization pressure, purge/feed ratio, pressure ratio and adsorption...
