Study of feed temperature effects on performance of a domestic industrial PSA plant

Abstract

The Parsian N2-PSA industrial plant, situated in the southern pars zone of Iran, was studied numerically by mathematical modeling and numerical simulation. The model coupled PDEs are solved using fourth order Runge–Kutta scheme. In this work, we are dealing with the feed temperature and investigating its effect on the N2 purity and recovery, which is known as an operating variable. Finally, the results of simulations showed that the feed temperature near to 25 °C is well suited to N2 production with respect to its purity and recovery. In addition, as the feed temperature increases N2 productivity decreases.
