Compression Technology Selection for Downstream Flare Gas Recovery
Flare gas recovery (FGR) captures low-pressure gas that would otherwise be flared and converts it into usable fuel or feedstock, while preserving the flare as the ultimate safety system. Compressor selection is not a simple efficiency comparison: gas composition and flow vary, suction is near atmospheric, liquid carryover is plausible, recovered-gas quality matters, and packages are typically procured within API-governed projects. This paper reviews integration and compares compressor types by CapEx, OpEx, reliability, and fit.
