摘要

A typical Skarstrom pressure swing adsorption (PSA) process consists of four basic operations, that is, pressurization, high-pressure adsorption, blow down and low-pressure purge. This sequence of operations is carried out in a series of fixed-beds in the same way but shifted in time. PSA processes, are, therefore, transient and cyclic in nature.The PSA process models are described by sets of partial differential algebraic equations (PDAEs). They are mainly constituted by conservation equations and models for the equation of state, equilibrium and thermodynamic and transport properties.
