渗透汽化膜技术及其应用
Pervaporation membrane separation technology and its application
摘要
Abstract
Membrane separation technology is contemporarily a high and new technology in chemical engineering. It has been consequently developed rapidly in recent 30 years due to the availability of solving many serious problems,such as energy,resources and environment. Membrane separation technology of pervaporation as a novel separation technology is typically energy-saving and cleaner-production technology. Compared to the conventional azeotropicdis-tillation and extractive distillation applied to azeotropic systems,pervaporation process could lead to an energy saving of 1/3~1/2 and decrease operating costs even no less than 50%. The industrial applications of the pervaporation dehydration over the world are introduced,and re-search progresses and industrial feasibilities of several pervaporation membranes are shown in this paper,which cover gasoline desulfurization membranes,methanol and ethanolpermselec-tive membranes,dimerthyl carbonate/methanol and arene/alkane separation membranes.关键词
