摘　　要：生物脱硫具有净化水平高、流程简单、污染少、能耗低等特点,能有效缓解硫排放引发的环境问题。为此,回顾了生物脱硫技术的发展历程,阐述了天然气生物脱硫技术的基本原理和工艺流程,总结了其技术优势以及国内外应用的概况,重点介绍了中国石油西南油气田公司天然气研究院在生物脱硫工艺技术开发上所取得的一系列成果:形成了适用于高含硫环境下分离筛选脱硫微生物的专利技术;获得了性能优良、具有自主知识产权的天然气脱硫微生物菌种;完成了脱硫溶剂配方体系和菌种培养方案的研究;同时,建立了天然气生物脱硫实验室评价装置,通过关键参数控制及过程优化,使得脱硫效果有了显著提升。最后指出了天然气生物脱硫技术的发展方向:①利用现代生物技术,提高脱硫菌种的性能;②应用流体研究技术,开发高效生物反应器;③完善配套技术研究,真正实现零排放;④优势互补,与现有工艺相结合。The biodesulfurization in natural gas sweetening process has such advantages as a high level of gas purification, a simple workflow, less pollution, low energy consumption, etc. and the most important of all, it can help mitigate the risk in environment pollution caused by sulfur emission. In view of this, after an overview of the history of biodesulfurization technology, this paper elaborates its basic principles and workflow. Then based on a brief summary of its technical superiority and its application at home and abroad, this paper presents in detail the achievements in this domain made by the Natural Gas Research Institute of PetroChina Southwest Oil ＆ Gasfield Company. （1） It is patented separating and screening the microbes for desulfurization. （2） The mixed animalcule bacteria with favorable performance are obtained with independent intellectual property rights. （3） The studies on the for mula system of desulfurization solvents and strains cultivating schemes have been completed. （4） An experimental evaluation unit is established for biodesulfurization, on this basis, the key parameters are as well controlled as the process is optimized, thereby the sulfurization result will be improved to a high level. In the end, this paper points out the developing trend of the biodesulfurization in natural gas sweetening process. First, the performance of sulfurization strains will be improved by use of modern biological technology. Second, fluid technology research will be adopted to develop a highly efficient bioreactor. Third, zero emission will be ultimately achieved by implementing the supporting technology research. Last, complementing each other＇s advantages, the current technology will be highly improved.
