Abstract

A dual reflux pressure swing adsorption (DR PSA) process was explored for N2 rejection from a binary mixture containing 75% CH4 and 25% N2 via non-isothermal numerical modelling. The four different configurations of DR PSA were studied and compared to observe their performance in separation. The simulation results show that A-cycles were generally superior to B-cycles in terms of methane purity and recovery. The impact of the feed locations was also studied and the results showed that feed positions had different influences on the four configurations, which indicated that changing the feed locations could afford more flexibility in process optimization.
