摘要
Abstract
The industrial process design lacks theoretical guidances for multiple target recovery from refinery gas. In this study,the concept of energy efficiency ratio was proposed for separation process. By using the electrical power to represent the energy associated with the variation of pressure and temperature during the gas separation process,a quantitative relationship between the energy consumption and the target product recovery was established. A typical refinery gas recycling process was taken as example,in which various separation technologies such as membrane or pressure swing adsorption(PSA)were utilized for thorough investigation. The energy efficiency ratios of various separation technologies and different separation processes were calculated. Results showed that,when H2 purity of product is relatively low(≥97%),PSA technology achieves the higher value of energy efficiency ratio(0.86),which is 28% higher comparing to the membrane separation technology. When H2purity of product is relatively high(≥99.9%),the hybrid membrane-PSA process achieves the higher energy efficiency ratio(0.54)than the hybrid PSA-membrane process,and the increase is about 40%. It indicates that the energy efficiency ratio can be employed to evaluate the efficiency of energy consumption of various separation technologies or different separation processes,and can provide a useful design guidance for refinery gas recycling process.关键词
