Progress of Yueneng Group’s 400,000 tons/year coal-based ethylene glycol project Author/Source: Date: 2019-04-17 Clicks: 8 On April 13, a meeting to discuss and evaluate the technologies related to ethylene glycol production and gasification for Yueneng Group’s 400,000 tons/year coal-based ethylene glycol project was held at the Yulin People’s Building. The meeting was chaired by Huang Ye, the deputy chief engineer of the group company and director of the Chemical Project Preparation Office. The conference specially invited Lin Binbin, Chief Engineer of China Tianchen Engineering Co., Ltd.; Zheng Huaan, Deputy Director of the Shaanxi Energy and Chemical Research Institute and Professor at Northwest University; Bai Xiaoniu, Jia Wugang, and Zhang Xu from Hualu Engineering Technology Co., Ltd., as well as several senior experts from domestic chemical enterprises operating in this field. Together, they conducted a thorough and comprehensive analysis of the current patent technologies related to ethylene glycol and powder coal gasification in China, and provided recommendations regarding the selection of ethylene glycol and gasification processes for the Yueneng project. The responsible persons from the relevant departments of the group company, as well as the technical staff from the ethylene glycol project department, attended this demonstration meeting. It was also learned that on April 12, the Ethylene Glycol Project Department held a review meeting on the general layout for Yueneng Group’s 400,000 tons per year coal-based ethylene glycol project. The overall design institute of the project presented the vertical and overall layout plans for the 400,000 tons per year ethylene glycol project, as well as its connection to the municipal pipeline network. After discussion, the participants agreed that the layout plan meets the planning requirements and is reasonable; relevant codes and standards must be strictly followed during the detailed design phase. Yuneng Group’s project for producing 400,000 tons of coal-based ethylene glycol per year is located in the Qingshui Industrial Park of the Yushen Industrial Zone. It covers an area of approximately 1,711 mu, with a total investment estimated at 5.8 billion yuan; completion and operation are scheduled for May 2021. In terms of the production process, coal-based syngas is used; carbon monoxide and hydrogen are separated through gas purification, and ethylene glycol is synthesized indirectly via carbonylation, coupling, and hydrogenation. Industrial products such as dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen are also produced as by-products. The main process units include those for producing coal-based syngas, purification and separation systems, ethylene glycol production facilities, boiler and power generation units, air separation plants, as well as various supporting utility systems. Once it is completed and put into operation, it is expected to generate annual operating revenue of 2.897 billion yuan, create profits of 607 million yuan for the enterprise, and provide employment for 600 people. It offers significant economic and social benefits, and plays a vital role in promoting the industrial transformation and upgrading of Yulin as well as achieving high-quality development. http://img.yf116.cn/image/img/20190418/1040323843242.jpg
