Bioregenerable Selective Sorbents for Hydrogen Sulfide Removal From Natural Gas

摘要

Natural gas contains impurities such as hydrogen sulfide (H H2S) which must be reduced to acceptable levels before the gas is suitable for use. Sulfides present problems such as human health risk, environmental compliance issues, corrosion, reduced efficiency of fluid handling equipment, reduced well production, offensive odor, reduced product value, and increased operation costs. Conventional treatment methods present problems such as high energy usage, disposal of hazardous waste materials, and high capital costs. S) Many new technologies have been investigated to improve the economics and safety of the gas desulfurization process. Biological oxidation of H H2S has several potential advantages including removal and elimination of H S H2S in one process, low energy requirements, and minimal disposal products. An improved version of the Bio-^sSep Sep~R Support matrix was created to immobilize the sulfide-oxidizing bacterium Thiobacillus denitrificans. The goal of this research is an economically viable bioreactor for H H2S removal through the use of this sulfide-sorbing, bioregenerable support matrix.
