Lifting of the turbine for the air separation unit in Yueneng’s coal-to-ethylene glycol project / Author/Source: Huahua Network – Coal Chemical Industry / Date: 2022-03-25 / Clicks: 3 On March 23, the turbine for the air separation unit in the syngas production facility of Yueneng Chemical Materials Co., Ltd.’s first-phase coal-to-ethylene glycol project with an annual capacity of 400,000 tons was successfully lifted, marking the start of intensive installation work on equipment, pipelines, and electrical systems at the project site. It is reported that the air separation unit uses a German Mannesmann two-in-one configuration, which mainly includes a turbine, an air compressor, and a booster; the turbine weighs 86.5 tons, the air compressor weighs 110 tons, and the booster weighs 25 tons. To ensure the safe and smooth lifting of the turbine and air compressor, the Project Management Department together with relevant departments organized relevant units to develop a detailed lifting plan. They also conducted thorough analyses of potential problems that might arise during the lifting process and formulated contingency plans to guarantee the smooth installation of the turbine. The first phase of the project to produce 400,000 tons per year of ethylene glycol as part of Shaanxi Yulin Energy Group Co., Ltd.’s 1.2 million tons per year ethylene glycol production capacity, is a project that marks the commencement of operations at the coal-based clean fuel and high-end chemical materials manufacturing bases located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned land area for this project is 711 mu, with an estimated investment of 6 billion yuan; the construction period is set at 30 months, and completion and operation are scheduled for 2022. The project construction includes a gasification unit, a purification unit, an H2/CO separation unit, an ethylene glycol unit, etc. The utility systems and supporting auxiliary facilities include: 3×350t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30MW back-pressure steam turbine generator sets, air separation units, circulating water stations, desalination stations, storage and transportation facilities, and sewage treatment plants. The coal gasification unit employs the Collin powder coal gasification technology and includes 2 powder coal gasifiers; the ethylene glycol unit uses the Zhongke Yuandong ethylene glycol technology. Carbon monoxide and hydrogen are used to indirectly synthesize ethylene glycol through carbonylation, coupling, and hydrogenation, with by-products including dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen.
