Routine flaring at Tabriz Oil Refining Company was investigated through an integrated approach combining source reduction and flare gas recovery. The study first monitored flare gas flowrate and composition, corrected measured flowrates based on gas composition, and inspected 492 points in the flare network to identify avoidable flaring sources. The stable routine flaring rate was estimated at 2.8–2.9 t/h, and 23 points were found to have a significant contribution. Corrective actions reduced routine flaring by about 700–800 kg/h. The remaining recoverable gas was then treated in an implemented flare gas recovery unit consisting of liquid separation, two-stage liquid ring compression, interstage cooling, amine absorption, and delivery to the fuel gas network. The average recovered gas flowrate was about 1050 Nm³/h. The project achieved an estimated net operating benefit of 0.76 million USD/year, a simple payback period of 5.5–6 years, and gross avoided CO₂ emissions of about 27,000 t/year.
