摘要
近年来,随着乙烯装置规模的不断扩大,所采用的压缩机组也越来越大型化。同时,对压缩机组的运行稳定性、可靠性以及安全性也提出了更高的要求。文章依托某大型乙烯装置的工程实践,介绍了国内首台裂解气压缩机用100 MW抽凝式汽轮机国产化研发过程,对该汽轮机的主要参数、结构配置、技术特点进行了阐述,其中多项技术开发的应用创新,解决了国内外乙烯装置中的一些关键性问题。该汽轮机的国产化,不仅节省了投资成本及维修费用、缩减了项目设计及安装周期,更为以后更大规模乙烯装置的设计及建设提供了坚实的技术保障。
In recent years,as the scale of ethylene plants continues to expand,the compressor units used are becoming larger and larger.Meanwhile,higher requirements are also put forward on the operational stability,reliability and safety of compressor sets.Based on the engineering practice of a large ethylene plant,this paper introduces the research and development process of localization of the first 100 MW extraction-condensing pumping turbine for cracked gas compressor in China.It expounds the main parameters,structural configuration and technical features of the turbine,in which a number of technological development and application innovation have solved some key problems in ethylene plants at home and abroad.The localization of this turbine not only saves investment and maintenance cost,reduces the project design and installation cycle,but also provides solid technical guarantee for the design and construction of larger-scale ethylene plants in the future.
