LPG胺净化过程中传质设奋的选择及应用进展

Selection and application progress of LPG amine purification process and mass transfer equipment

本文较全面地介绍了用于液化气(LPG)胺净化的主要几种传质设备的类型及其应用进展。重点介绍了它们各自用于处理LPC的传质效率;并得出高效填料塔比乱堆填料塔和板式塔可获得更大的混合效果和传质效率,传质设备的优化选择是提高LPC胺吸收效率的关键因素之一。

The article gives an overall view of mass transfer equipment types and their application progress in the service of LPG amine purification. Introduction is emphasized on mass transfer efficiencies of those equipment used as treating LPG. It is concluded that high efficiency packing column can obtain much greater mixing effect and mass transfer efficiency, compared to bulk column and plate column, optimization of mass transfer equipment is one of key factors to increase LPG's amine absorption efficiency.
