Abstract:
A Fugitive Emissions Recovery System (FERS) for a Process Gas Compressor Train recovers all process gas leakage from each PGC case by creating a slight vacuum in the PGC lube oil reservoir, the bearing housings on each compressor case, the PGC lube oil reclaimer, and the PGC sour oil holding tank. This vacuum is accomplished without compromising the over-pressure protection of the aforementioned compressor components and without allowing air leakage into the FERS. All recovered PGC seal leakage is routed to a furnace for combustion. A closed-loop lubrication system is used.
