Simulation of N2 Gas Separation Process from Air

Abstract

Various components of air have been separated for different purposes for their easy availability in the atmosphere. Among those components Nitrogen separation process is very important in chemical engineering sector since it has wide usage in different processes. There are various technologies that are used for the separation of nitrogen. Among those most common is via LINDE-HAMPSON cycle. This paper presents analysis of thermodynamic cycle commonly used for liquefaction of Nitrogen (N 2) under given set of operating condition and efficiencies. The liquefying temperature of Nitrogen being-200 o C is taken into consideration. This paper also presents the simulation of this process HYSYS for the separation of N 2 from air. Simulation result gives the value of product nitrogen purity of 91.75%.
