Patent ID: 7758335

Claim:
Method for utilizing a combustible gas product collected in a compressor of the said combustible gas product, the compressor having a seal device, the method comprising the steps of: a) feeding the seal device of the compressor with an inert gas flow, wherein the compressor increases the pressure of a combustible product, wherein at least a portion of the gas flow of the combustible product collects in the seal device, and wherein the seal device comprises an outlet, b) recovery at the outlet of the seal device of a composite gas flow containing all or part of the inert gas flow of step a) and all or part of the gas flow of combustible product collected in the compressor seal device, to supply a line connected to the outlet of the seal device, c) separation of the composite gas flow at the outlet of the line into two gas flows, the first being intended to feed a fuel header connected to burners, and the second being sent to a flare to be burned, the lines conveying the gas flows of steps b) and c) comprising a leak circuit, wherein the pressure in the seal device is maintained at a pressure above the gas pressure in the fuel header.
