Abstract

Abstract: 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.

Key words: ethylene plant, cracking gas compressor, steam turbine, high efficiency, stability, localization
