| Abstract: | The principle of volatile organic compounds recovery based on membrane technology was described. Propylene recovery from noncondensable gas of small polypropylene plant was presented. The application of propylene recovery from noncondensable gas by compression/condensation/membrane separation hybrid system showed obvious effect. A remarkable saving in energy and propylene consumption was realized, which led to prominent economical and social benefit. Propylene recovery up to 95 % was obtained with 7 % propylene molar concentration in vent gas. |
