膜分离技术在油气回收中的应用

在油品储运、销售、应用过程中，存在着大量的油品蒸发损耗。可用膜分离技术来分离回收轻质油品蒸发排放出来的油气。介绍膜法油气回收的分离机理、应用实例和工艺设计数据，综合比较常用的吸收法、吸附法、冷凝法及膜法油气回收技术并获得各自的量化分值，认为膜法回收技术为目前较有可能及较容易取得突破成果的研究领域。最后指出今后的研究重点。

APPLICATION OF MEMBRANE SEPARATION TECHNOLOGY IN PETROLEUM PRODUCTS VAPOR RECOVERY

In the process of light petroleum products ( such as gasoline ) loading, unloading, storage, transportation, or distribution, a great deal of mixtures of the petroleum vapor and air are emitting from the tank or tanker. Membrane separation technology can be applied to separate and recover the vapors from the mixtures produced in the so - called transfer operations. The separation mechanism and some application samples are introduced and key technical design data are recommended. A comprehensive evaluation table is designed to compare and appraise it with the other traditional separation technologies by adsorption, absorption, and condensation. The evaluation results show that as a later high - tech, some key problems from applying the method to recover the vapor and some key effect factors on the recovery efficiency need be analyzed and answered, and it is predictable and certain that many notable achievements will be obtained in developing the technology in the near future in China.
