Microbial Modification Enhances Organic Sulfur Removal Capability of Chelated Iron Solution for Natural Gas.

ABSTRACT: Feedstock natural gas typically contains sulfur compounds, such as hydrogen sulfide (H₂S), carbonyl sulfide (COS), and methyl mercaptans (MeSH), which require removal before pipeline transportation. The chelated iron process, a liquid-phase oxidation method, is widely employed for desulfurizing refinery gas, natural gas, and biogas due to its low capital investment, operational simplicity, and cost-effectiveness. While highly efficient for H₂S removal, the chelated iron process exhibits limited effectiveness against organic sulfur compounds like COS and MeSH, restricting its applicability. Certain microorganisms demonstrate strong organic sulfur removal capabilities. While biodesulfurization effectively treats low-sulfur streams, its standalone configuration shows ina
