| Abstract: | The conformation of composite membrane and the principle of volatile organic compounds recovery based on membrane technology are described in this study. A propylene recovery process from incondensable gas of batch- type polypropylene plant is presented. The application of the propylene recovery process from incondensable gas by compression/condensation/membrane hybrid system shows obvious effect in CNPC Qianguo Refinery. A remarkable saving in energy and stock consumption is realized, which leads to the prominent benefits of economy and society. The recovery up to 95 % for propylene together with 7 % propylene molar concentration in vent gas is reached. |
