Stop sour gas flaring: Advances in H2S treatment drive improved economics
11/5/2025
FIG. 1. Gas can be recovered, which makes the wasteful and environmentally damaging practice of flaring unnecessary. Driven by increased global demand for natural gas and liquefied natural gas (LNG), countries across all oil-producing continents are addressing the removal of hydrogen sulfide (H2S) from both gas and oil extraction. This continues to be one of the industry’s longstanding economic and environmental challenges. Treating H2S adds costs, so operators prioritize sweet formations when all other attributes are equal. However, areas with high concentrations of sour formations—including the Middle East, Kazakhstan, Canada, and the U.S., among other countries—all contain huge rese
