At 11:20 on March 28th, the primary power supply was successfully established at the substation in tank area 310 of the first-phase project of Shaanxi Yueneng Chemical Materials Co., Ltd., part of Shaanxi Yulin Energy Group, with a production capacity of 1.2 million tons per year of coal-based ethylene glycol; this marked the successful establishment of power supply to all substations in the ethylene glycol project. At 9:00 a.m. on March 28, the power supply process officially began. After a series of inspections and verifications, the staff strictly followed the monitoring and repetition procedures, carefully checking the names, numbers, and locations of the equipment. They then carried out the switching operations in accordance with the predetermined plan. At 11:20 a.m., the primary power supply to the substation in Tank Area 310 was successfully established. The substation in Tank Area 310 primarily supplies power to the product tank areas of the company’s ethylene glycol project, as well as to the flare stack, loading/unloading stations, accident ponds, and cabinet rooms in the tank area. The successful primary power supply to the substation in Tank Area 310 has laid a solid foundation for the project to proceed smoothly into the single-unit testing and commissioning phase. The first-phase project of Shaanxi Yulin Energy Group Co., Ltd., which involves the production of 1.2 million tons per year of ethylene glycol, with an initial capacity of 400,000 tons per year, is part of the initiatives undertaken by Yulin Energy Group in the Clean Fuel Production Base and High-End Chemical Materials Base located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned land area for this project is 1,711 mu, and the investment required is 6.243 billion yuan. The project uses blended coal as raw material and employs Collin powder gasification to produce crude syngas. Ethylene glycol synthesis is a technology of Zhongke Yuandong. The 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, sewage treatment plants, etc.
