4th Stage Separators

Mott GSV (Gas Solids Venturi) 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 to 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 related components, requiring this equipment to be taken offline for service and resulting in costly process disruptions.  When installed on the underflow stream from the third stage separator, a sintered metal filter substantially reduces the loss of expensive catalyst and often provides a payback period of less than one year.
