Sulfide species (inorganic and organic sulfides) are well known for their toxicity and corrosiveness. Several industries, including oil and gas, are prone to corrosive damage due to sulfides that necessitate their timely removal using appropriate methods. Employing chemical scavengers is the most suitable method where the scavenger combine with dissolved sulfides in aqueous/hydrocarbon phase and convert them to a nontoxic and less corrosive form that can be easily removed from the stream. Instead of direct chemical scavenger addition, different approaches, including absorption and adsorption methods, are employed in eliminating sulfide species from gas streams in different industrial applications. This review provides a detailed account of various sulfide scavengers used in oil and gas sweetening. Most recent research advancements in this area are highlighted. A brief account of the latest reported works on novel adsorbents for the desulfurization process for refinery fuels is also provided. The review ends with a short discussion on catalytic hydrodesulfurization.

石油和天然气行业硫化物清除剂的研究进展

硫化物（无机和有机硫化物）以其毒性和腐蚀性而闻名。包括石油和天然气在内的多个行业都容易因硫化物而导致腐蚀损坏，因此必须使用适当的方法及时将其清除。使用化学清除剂是最合适的方法，其中清除剂与在水/烃相中溶解的硫化物结合，并将它们转化为无毒且腐蚀性较小的形式，可以很容易地从物流中去除。代替直接添加化学清除剂，在不同的工业应用中，采用了包括吸收和吸附方法在内的不同方法来从气流中消除硫化物。这篇评论提供了油气脱硫中使用的各种硫化物清除剂的详细说明。重点介绍了该领域的最新研究进展。还简要介绍了炼油厂燃料脱硫过程中有关新型吸附剂的最新报道。审查以关于催化加氢脱硫的简短讨论结束。
