Ceremony held for the EPC project of concentrated brine in Yueneng Chemical’s ethylene glycol production project Author/Source: Yueneng Chemical Date: April 30, 2022 Views: 37 At 11 a.m. on April 29, a ceremony was held to mark the start of the EPC project for concentrated brine in Yueneng Chemical’s 400,000-ton/year ethylene glycol production project. Li Zhengang, a member of the company’s Party committee and deputy general manager, Wang Wuping, the chief engineer, Li Yucun, the deputy chief engineer, as well as representatives from the engineering management department, the supervision unit, and the project owner attended the ceremony. 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 start 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 area for this facility 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.
