Successful commissioning of the world’s largest turbine for driving waste gas compressors Author/Source: Coal Chemical Industry 114 Forum Date: 2020-09-08 Clicks: 57 In Xinjiang Hami’s 400,000-ton ethylene glycol project, the most important piece of equipment – the HS61029 turbine used to drive the waste gas compressors – has been successfully commissioned! As the key component of the project’s process, the raw gas compressor; its ability to operate stably over the long term is crucial to the future success of the ethylene glycol project. The parameters of the turbine driven by the waste gas compressor in this project are as follows: steam inlet pressure of 8.83 Mpa and temperature of 530 ℃, rated power of 37,070 kW, and rated speed of 4,829 RPM. It currently possesses the highest single-unit power among all turbines used with waste gas compressors worldwide. At the same time, the waste gas compressor needs to be started and stopped frequently on an irregular basis during operation, which imposes extremely strict requirements on the quality of the drive equipment, namely the turbine, as well as on its operational stability. The successful commissioning of this unit signifies that Hangzhou Zhongneng has become the manufacturer of impulse turbines with the highest single-unit power in China’s industrial drive sector. It also provides us with strong capabilities to advance as a leading manufacturer of impulse turbines in the global industrial drive industry in the future. The construction of the Guanghui ethylene glycol project is located in the Naomaohu Industrial Park, Yiwu County, Hami City, Xinjiang, with a total investment of 3.56 billion yuan. The project adopts the third-generation \"WHB syngas-based polyester-grade ethylene glycol\" technology, jointly developed by China Five Rings and Huashuo Technology Co., Ltd. as well as Hebi BMW (Group) Co., Ltd. Through a series of processes including conversion, shift reaction, low-temperature methanol washing, and PSA adsorption separation, the valuable syngas components H2 and CO present in raw gas are extracted, and high-end chemical products—polyester-grade ethylene glycol—are produced using carbonylation, hydrogenation, and purification technologies.
