In API Plan 52 external reservoir provides buffer fluid for the outer seal of an un-pressurized dual seal arrangement ( Arrangement 2). During operation an internal pumping ring provides circulation. The reservoir is connected to a vapour recovery system and is maintained at a pressure less than the pressure in the seal chamber. It is normally used for the applications where process fluid leakage to atmosphere must be minimised and contained. Plan 52 works best with clean, non-polymerising pure products that have vapour pressure more than the buffer system pressure. Leakage of higher vapour pressure process liquid into buffer system will flash in the seal pot and escape into the vent system. Leakage of the process fluid will mix with the buffer fluid and contaminate the buffer fluid over a time. Therefore the buffer fluid must be compatible with the process fluid.
