Recently, a meeting was held at Donghua Engineering Technology Co., Ltd. to advance the preliminary design for the olefins, aromatics, and advanced processing components of Phase 2 of Yulin Chemical Co., Ltd. (referred to as “Yulin Chemical”)’s 15 million tons/year demonstration project for clean and efficient conversion of coal on a differentiated basis. Song Shijie, Assistant General Manager of Shaanxi Coal Group and Chairman of Yulin Chemical Company, Liu Wansheng, Chief Engineer of Yulin Chemical Company, officials from relevant departments, as well as representatives from Donghua Engineering Technology Co., Ltd., China Global Engineering Corporation, Hualu Engineering Technology Co., Ltd., Northwest Electric Power Design Institute Co., Ltd. of China Power Engineering Consulting Group, Sinopec Ningbo Engineering Co., Ltd., and Sinopec Luoyang (Guangzhou) Engineering Co., Ltd., attended the meeting. At the meeting, Song Shijie presented an overview of Shaanxi Coal Group’s operational performance in 2022, as well as the progress on the 1.8 million tons per year ethylene glycol production project at Yulin Chemical, the pyrolysis phase of the 15 million tons per year demonstration project for clean and efficient coal conversion, the DMC project, the Yumen project, and the preparations for the CCS demonstration projects. He noted that the total investment for the second-phase project amounts to approximately 201.4 billion yuan. It is a super-large-scale modern coal chemical project that bears the important task of driving the transformation and development of the chemical industry under Shaanxi Coal Group, and it is tasked with promoting the upgrading and sustainable development of the high-end energy and chemical industry base in northern Shaanxi. He emphasized the need to make full use of the experience and knowledge accumulated during the first phase of project construction, as well as various management tools such as project management platforms, document management systems, handover documentation management systems, archive management systems, and ERP systems. By focusing on areas such as design, procurement, and construction, it is possible to achieve fully digital delivery, thereby creating a model enterprise for smart factories ； Donghua Technology should focus on design optimization and carry out comprehensive planning; it should take the lead in conducting specialized research and evaluations related to the second-phase project, and invite experts to participate in discussions when necessary in order to produce specialized research reports ； All design agencies must attach great importance to this task, assume their responsibilities, ensure adequate provision of resources, recruit and retain high-quality talent in all relevant fields, provide timely guidance and coordinate solutions to various issues, so as to complete the design work on time and to a high standard. The engineering design manager for the second phase of Donghua Technology reported on the progress of the basic design for this phase, the product concepts, and the timeline for completing the basic design. Relevant personnel from various design firms made statements, all agreeing that the second-phase project of Yulin Chemical is a key project for these firms, and they will go all out to advance the preliminary design work. Subsequently, the participants had a detailed discussion on the next steps for work and the issues that need to be addressed urgently, and formulated a work plan to lay a solid foundation for accelerating the second phase of the project. It is reported that the demonstration project for the clean and efficient conversion of 15 million tons per year of coal into various products will be carried out in two phases; phase one involves the construction of an ethylene glycol production facility with a capacity of 1.8 million tons per year, as well as projects related to pyrolysis. In the second phase, building on the foundations of the first phase, olefin, aromatic hydrocarbon, and advanced processing facilities will be established. These facilities will utilize coal in an efficient manner through targeted sorting and grading to produce major platform products such as olefins, aromatic hydrocarbons, and base oils. Further processing will then be carried out to produce four categories of end products with high added value: specialty materials, battery electrolyte solvents, biodegradable materials, and special oils, thereby achieving coordinated development between coal chemical industry and petroleum chemical industry.
