On May 16, the steam drum of Boiler No. 3 in the power center of the company’s ethylene glycol project was successfully installed in place. The successful lifting of the steam drum marks the full entry of the three boilers in this project into the intensive installation phase, laying a solid foundation for the subsequent boiler hydrostatic testing. The steam drum of Boiler No. 2 in the power plant was manufactured by Harbin Boiler Factory Co., Ltd.; it has an inner diameter of Ф1600 mm, a thickness of 70 mm, and a length of approximately 13,500 mm. The material used is 13MnNiMo5-4. The elevation of the center of the steam drum is 47,078 mm, and the lifting weight of this equipment is 63.5 tons. 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 gasification unit employs the Collin powder gasification technology and includes 2 powder 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.
