From March 30 to 31, the review meeting on the key technological innovation plans for the dimethyl oxalate and ethylene glycol processes in the 1.8 million tons per year ethylene glycol production facility, as part of the first phase of Shaanxi Coal Group Yulin Chemical Co., Ltd.’s project on the utilization of coal in order to produce new materials, was successfully held in Hefei. Representatives from Shaanxi Coal Group Yulin Chemical Co., Ltd., Donghua Engineering Technology Co., Ltd., and Takasago Chemical Co., Ltd., along with invited experts from related industries both domestically and internationally, attended the meeting. The demonstration project for the production of new materials through the differentiated utilization of coal by Shaanxi Coal Group Yulin Chemical Co., Ltd. is a large-scale coal conversion project that was given priority in Shaanxi Coal Group’s plans during the 13th Five-Year Plan period; it is located in the Qingshui Industrial Park in Yulin City. In one of the phases of this project, which involves an ethylene glycol production capacity of 1.8 million tons per year, there are 9 sets of equipment for the synthesis of dimethyl oxalate, resulting in a total capacity of 3.78 million tons per year; alongside these, there are 3 sets of equipment for ethylene glycol synthesis, with a capacity of 1.8 million tons per year. This facility represents the largest coal-based ethylene glycol production plant in the world, and it is scheduled to be completed and put into operation by the end of June 2021. At the meeting, Zhang Xiaojun, General Manager of Yulin Chemical Company of Shaanxi Coal Group, presented the latest progress of the project, acknowledged the hard work of Donghua Technology Company and Kako Chemical Co., Ltd., and put forward clear requirements for the key technological innovation solutions in this process package. Chen Zhirong, deputy general manager of Donghua Technology Company, said that the company will do its utmost to cooperate with all parties involved in order to carry out high-quality process technology design and engineering design for the ethylene glycol production unit of this world’s largest coal-based ethylene glycol project. Donghua Technology Company and Kao Chemical Company provided detailed reports on the specific key technological innovations included in this process package, as well as analyses of their economic viability and feasibility. The expert group conducted a thorough and careful review and discussion of the above content, and finally agreed unanimously that the key technological innovations in this process package further enhance the safety, economic efficiency, and environmental friendliness of the facility; it is recommended that this project adopt them ； Innovative solutions that have not reached an agreement still require further research and validation. It is reported that this review meeting on the key technological innovation solutions for the process package is an extension of the process package review process. The successful completion of this meeting has laid the foundation for the implementation of the 1.8 million tons per year ethylene glycol project, essentially removing the obstacles to transitioning the ethylene glycol plant from the design phase of the process package to the engineering design phase. http://img.yf116.cn/image/img/20190403/856523221220.jpg http://img.yf116.cn/image/img/20190403/857283224821.jpg http://img.yf116.cn/image/img/20190403/85843228467.jpg
