The kick-off meeting for the concentrated brine unit of Yueneng Chemical’s ethylene glycol project was held successfully! Author/Source: Yueneng Chemical Date: 2022-03-18 Clicks: 18 On March 17, the kick-off meeting for the concentrated brine unit of Yueneng Chemical’s ethylene glycol project was successfully held in the conference room of Building No. 4. Wang Wuping, the chief engineer, Li Yucun, the deputy chief engineer, design representatives from China Tianchen Engineering Design Institute, Aerospace Building Design and Research Institute Co., Ltd., Hebei Delong Environmental Protection Company, as well as the company’s relevant technical management personnel attended the meeting. During the meeting, the participants had thorough discussions on matters such as the milestone dates for the construction of the brine treatment unit in the company’s ethylene glycol project, the project coordination procedures, the allocation of key equipment, and the start date for civil works. This led to a unified understanding among them and a clearer definition of responsibilities. The concentrated brine treatment unit for Yueneng Chemical Materials Co., Ltd.’s coal-based ethylene glycol production project was EPC-general contracted by a consortium consisting of Aerospace Building Design and Research Institute Co., Ltd. and Hebei Delong Environmental Engineering Co., Ltd. The contract value was 136.10188 million yuan. This concentrated brine treatment system is designed to handle the concentrated water resulting from the RO treatment in the reclaimed water reuse system, as well as the regenerated wastewater from the desalination plant; its design capacity is 210 m3/h, with an annual operating time of 8,400 hours. The unit is capable of operating at loads ranging from 50% to 110%. 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 1,711 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 Corin 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 and coupled hydrogenation, with by-products including dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen.
