The installation and operation of suitable separation and filtration systems have become key components of virtually all process units, especially amine units. These systems allow each amine unit to run in a stable manner and with greater tolerance to disturbances and to changes in the process. The separation technologies serve as the last, and only, line of defense for the disposal of contaminants. If these systems are not designed, built and operated correctly, then the amine units regularly suffer from several inefficiency problems, such as high operating costs, lean separation efficiency of H2S/CO2, amine losses and excessive maintenance.  Part 2 of this article details the use and appl
