COMPRESSOR SYSTEM EQUIPPED FOR FUGITIVE GAS HANDLING AND FUGITIVE GAS SYSTEM OPERATING METHOD

摘要

A compressor system (10) includes a gas compressor (18) with dry gas seals (66, 68) about a driveshaft (64). The compressor system (10) also includes a fugitive gas system (30) having a gas conduit (36) in fluid communication with a collection cavity (34, 35) in a collector (32) coupled to the gas compressor (18) to receive fugitive gas leaked through a pressurized gas leakage path (67, 69). The fugitive gas system (30) may be structured for flaring the gas, and includes a pressure control system (42) with an accumulator tank (44), and a vent line (46) for venting gas pressure and having a backpressure regulator (52) therein. Fugitive combustible gas is conveyed through a flow restriction orifice (96, 100) downstream of the compressor (18).
