Microbial process for the mitigation of sulfur compounds from natural gas

摘要

An anaerobic process of desulfurizing a sour natural gas stream wherein a selected consortium of chemoautotrophic bacteria converts H2S and other sulfur species into elemental sulfur, which is recovered as a product. The process is conducted at pressures of up to 1000 psi and temperatures up to 140 DEG F. (10 DEG C. to 60 DEG C.), and mitigates up to 10,000 ppm H2S to pipeline standards of
