In accordance with the company’s construction schedule, the H2S concentration tower (122T-003) for the purification unit at Yueneng Chemical’s syngas center has been successfully installed. The H2S concentration tower is the equipment with the lowest temperature in the low-temperature methanol washing unit; its main function is to remove the remaining CO2 gas from the methanol-rich stream through nitrogen stripping. The H2S concentration tower is 65.97 meters tall and 3 meters in diameter, with a net weight of 101.3 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 coal-based ethylene glycol production capacity, is a project that marks the commencement of operations at the coal-based clean fuel 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 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, as well as 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.
