On the afternoon of June 14, the steam turbine generator set in Yueneng Chemical Company’s power center was successfully installed in place. The successful installation of the steam turbine generator set has created favorable conditions for subsequent installation work, laying a solid foundation for the early commissioning of the company’s power center. The steam turbine generator set uses a turbine produced by Shanghai Steam Turbine Works, with a rated power of 30 MW, a rated steam inlet pressure of 9.3 Mpa, a rated extraction steam pressure of 2.7 Mpa, and a rated exhaust steam pressure of 1.3 Mpa. It is a high-temperature and high-pressure, single-cylinder regenerative, reaction-type turbine with exhaust steam at the bottom and extraction steam under backpressure; it is used in conjunction with a generator of a certain model manufactured by Shanghai Electric Power Station Equipment Co., Ltd. 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 coal-based 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.
