Using pressure swing adsorption (PSA) technology to purify carbon monoxide (CO) discharged from industrial gases is a high-efficiency and economical method. In this article, a four-bed PSA experiment for CO purification was improved and optimized, in which a set of 120 m^3·h^-1 pilot-scale PSA device was developed to purify CO from industrial tail gases, a set of control systems suitable for industry production was developed, and the influences of the operating parameters on CO purification were investigated. The experimental results indicated that the pilot-scale PSA device could produce qualified product gas and get high CO recovery ratio under optimized conditions. The research may provide reliable fundamental data, for industrial scale utilization of CO, from industrial tail gases, and have strong market competitive power and a broad promoted application prospect. 相似文献

变压吸附数学模型30年进展 总被引:1,自引:0,他引:1
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 modes,some influential factors, such as pressurization with product,incomplete purge, beds with dead volume and heat effects,are discussed respectively.With several approximate assumptions i.e., concentration profile in adsorbent,“frozen” column,symmetry and heat effects of bed wall,the more complex kinetic models can be simplified to a certain degree at the expense of a limited application.It has also been found that the electrical analogue model has great fxexibility to handle more realistic PSA processes without any additional hypothesis. 相似文献
