The detailed design review meeting for the gasification unit of Shaanxi Coal Group Yulin Chemical’s 1.8 million tons per year ethylene glycol production project was held at Tianchen Company. Author/Source: Coal Chemical Industry 114 Forum Date: 2020-09-02 Clicks: 4 From August 24th to 28th, the detailed design review meeting for the gasification unit of this project was held at Tianchen Company. Relevant departments of the company, as well as technical personnel from Colin Future Energy Technology (Beijing) Co., Ltd. and China Tianchen Engineering Co., Ltd., attended the meeting. During the review meeting, the relevant technical personnel conducted a thorough examination of the detailed design documents related to the gasification unit’s processes, equipment, instruments, and electrical systems, as well as of the issues that needed to be resolved during the review of the 90% 3D models. At the same time, the design aspects such as the technology of the complete set of supplied equipment, the equipment itself, instruments, pipelines, control systems, and the layout of electrical instrument trays were carefully discussed. Upon review, the content and depth of the design documents for the gasification unit meet the requirements specified in the \"Regulations on the Detailed Engineering Design Requirements for Petrochemical Units\" (SPMP-STD-EM2005-2016). The review was successful, marking the entry of the gasification unit’s design work into its final stages and laying a solid foundation for on-site construction and commissioning. Yulin Chemical is carrying out the construction of a demonstration project for the production of new chemical materials through the differentiated utilization of coal in the Qingshui Industrial Park of the Yushen Industrial Zone. As the largest coal chemical project under construction globally at present, this project covers an area of approximately 13 square kilometers. The total planned investment is 126.2 billion yuan, and it will be able to process over 24 million tons of coal per year. The project is constructed in two phases and four stages, comprising a total of 27 process units along with associated utility systems. These mainly include the medium- and low-temperature pyrolysis of 15 million tons of coal, the production of 5.6 million tons of methanol, 1.8 million tons of ethylene glycol, 2 million tons of MTO, as well as downstream products derived from these intermediates. The first phase of the project requires an investment of around 70 billion yuan; it will involve the construction of facilities for producing 1.8 million tons per year of ethylene glycol, 5.6 million tons per year of methanol, and 2 million tons per year of olefins, as well as a large amount of fine chemical products derived from these olefins. The 1.8 million tons per year ethylene glycol production facility is part of the first phase of this project; it is also the largest coal-based ethylene glycol production plant under construction worldwide. The estimated investment for this facility is 26.5 billion yuan. The project utilizes Collin’s patented dry powder gasification technology and Japan’s patented technology for producing ethylene glycol from syngas. Shaanxi Coal Group Yulin Chemical Co., Ltd. and Nippon Kako Kagaku Co., Ltd. jointly invested in establishing Shaanxi Coal Group Yulin Chemical Yugao Chemical Co., Ltd. to build and operate facilities for the production of oxalate esters as well as for the hydrogenation of oxalate esters to produce ethylene glycol. One of the overall goals set for the project construction is that by June 30, 2021, both the first phase of Project Phase I, which involves an ethylene glycol production facility with a capacity of 1.8 million tons per year, and the first phase of Project Phase II, which includes a coal pyrolysis facility with a capacity of 1.2 million tons per year along with a pilot plant for the advanced processing of coal tar with a capacity of 500,000 tons per year, shall reach mechanical completion – this goal is referred to as “21630”.
