Hydrogen sulfide (H2S) is a harmful gas that needs to be removed from natural gas for safety and health reasons. Traditional methods are costly and complex, so scientists are exploring biological solutions. One common method, THIOPAQ™, uses microorganisms to turn H2S into sulfur. Another method, SCOT, is the industry standard but can be expensive. A study compared the two methods and found that the biological process is safe, simple, and cost-effective compared to SCOT.
