变压吸附制氧过程传质特性数值分析
Numerical analysis of mass transfer characteristics during pressure swing adsorption oxygen production process
摘要
Abstract
The effect of adsorption time on the performance of pressure swing adsorption(PSA)oxy-gen production process was experimentally investigated and a concentration wave model was proposed for analyzing the mass transfer characteristics and calculating the optimal adsorption time during the PSA process.The results showed that the shape of N2 loading profile at adsorption step changed with time and axial position,and the propagation velocity of the N2 concentration wave with ideal conditions was greater than the practical propagation velocity.The limited heat and mass transfer resistance slowed down the propagation of the concentration wave during the practical adsorption process,and the reduction degree of the concentration wave velocity was about 26％.The errors between the opti-mal adsorption time calculated though the concentration wave model and the experimental adsorption time were within 0.5 s.关键词
