Emissions from flares worsen air quality and produce waste gas. A flare gas recovery system (FGRS) is designed to facilitate CO2 reduction. In a recent project, an engineering and construction company optimized an FGRS design by utilizing a high-performance ejector as a compressor, a three-phase separation tank, a self-purification loop of sour water, a software simulationa of the amine scrubber and a dynamic simulation of flare gas discharge.
