Progress in Pressure Swing Adsorption Models During the Recent 30 Years

摘要

The pressure swing adsorption (PSA) models discussed here are divided into three categories: partial differential equation model, electrical analogue model and neural network model. The partial differential equation model, including equilibrium and kinetic models, has provided an elementary viewpoint for PSA processes. Using the simplest equilibrium models, some influential factors, such as pressurization with product, incomplete purge, beds with dead volume and heat effects, are discussed respectively.
