4th Stage Separators

Mott GSV Filters are utilized to recover and transfer catalyst fines to a storage hopper and to ensure particulate emissions are minimized, not only protect downstream equipment but also limit the amount of emissions released into the environment.  When particulates are allowed to remain in the gas stream, they can cause fouling, plugging, and erosion of downstream equipment, including the turboexpander, waste heat boiler, and their components, requiring that this equipment be taken offline for service, resulting in costly process disruptions.  Installed on the underflow stream from the third stage separator, a sintered metal filter so substantially reduces the loss of expensive catalyst that it often provides a payback period of less than one year.
