Abstract： Aiming at the localization of steam turbine for cracking gas compressor with annual output of one million tons of ethylene device，it was introduced that the background and process of the project based on the instance of the application of steam turbine research and development projects in Tianjin Petrochemical. Combined with conforming and implementation of the development scheme which relies on the first domestic set of steam turbine used in this condition，it was described in detail the main technical parameters，structure configuration，technical characteristics and the international standard needed to be complied with，as well as the key issues，research difficulties and the measures. In the end，the three innovation patents were introduced which were achieved during the process of the steam turbine's development of localization. The results indicate that the localization of the steam turbine is completely realized.
