Review of the Overall Design for the First Phase of Shenhua’s 100-billion-yuan coal chemical project. Author/Source: Date: 2017-10-30. Clicks: 35. From October 23 to 26, a review meeting on the overall design of the project aimed at producing 1.8 million tons of methanol and 400,000 tons of ethylene glycol per year as part of Shenhua Yulin’s circular economy coal utilization project (Phase 1) was held at Donghua Technology. The expert review panel for this review was composed of 23 experts from various subsidiaries of Shenhua Coal-to-Oil, Tianchen Company, Chengda Company, Hualu Company, and other organizations; the panel conducted a comprehensive and thorough examination of the overall design. Review of the overall design for the first phase of Shenhua’s 100-billion-yuan coal chemical project. The Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project (CTC Project) was approved for implementation by the **National Development and Reform Commission in March 2015; it is currently the largest coal chemical project in the world in terms of investment, with a planned total investment of 120 billion yuan. The first-phase project of the Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project is a preliminary phase of this project (the CTC Project). It also serves as a facility for producing methanol raw materials to support the already completed Shenhua Shaanxi Methanol Downstream Processing Project (SSMTO). The construction scope includes an annual production capacity of 1.8 million tons of methanol along with 400,000 tons of ethylene glycol per year. The facility comprises various process units such as air separation, gasification, shift reaction, acidic gas removal, methanol synthesis, sulfur recovery, and ethylene glycol production, along with the associated utility systems and auxiliary facilities. Once completed, it will enable integrated production and management with the SSMTO project. Over the course of four days, the experts present engaged in open discussions with the designers, pooling their ideas. They conducted a thorough and detailed review of the overall project design from various aspects such as manufacturing processes, equipment, instrumentation, electrical systems, and cost estimates. As a result, they formulated scientific, reasonable, and feasible recommendations, which laid a solid foundation for subsequent work and provided a reliable basis for further optimizing the design. On June 15, 2017, the groundbreaking ceremony for the first phase of Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project was held in the Qingshui Industrial Park of the Yushen Industrial Zone. The total investment for this first phase amounts to 13.6 billion yuan. The project is located in the northern part of the Qingshui Coal Chemical Industry Park within the Yushen Industrial Zone; it is planned to complete work such as the construction of the area in front of the plant, the leveling of the land surrounding the plant, and the building of walls around it this year. Construction has also begun on the accommodation buildings for the subcontractors. The entire project is to be constructed and operated after completion by Shenhua Yulin Energy Chemical Co., Ltd., with the plant set to begin operations in 2020. http://img.yf116.cn/image/img/20171030/933303441025.jpg In 2014, the Shenhua Dow Chemical Integrated Coal Chemicals Project in Yulin, Shaanxi, was affected by Dow Chemical’s unilateral withdrawal; the project was later transformed into the “Shenhua Circular Economy Coal Comprehensive Utilization Project” (the Shenhua Northern Shaanxi Billion-Yuan Coal Chemicals Project), with Shenhua Group taking the lead and several state-owned enterprises from Shaanxi participating in it. The Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project was officially launched on March 27, 2015, in the Yushen Industrial Zone of Shenmu County. Using coal as raw material and employing GE’s large-scale, high-efficiency water-coal slurry gasification technology, the project is capable of producing 1.8 million tons of methanol per year (for the production of olefins), as well as 400,000 tons of ethylene glycol and other high-value-added products. In total, it generates 2.17 million tons of chemical products per year, including more than 100 different grades of alcohols, acids, esters, amines, and ethers. The project consists of process units such as air separation units, gasification units, CO conversion units, acid gas removal units, sulfur recovery units, methanol synthesis units, and ethylene glycol production units, along with supporting utility systems and auxiliary facilities. It is also integrated organically with the various systems of the existing Shenhua Shaanxi methanol downstream processing project.
The four major coal chemical engineering design institutes are all involved in this project; it seems that Tianchen has taken on the heavier workload, while Chengda has a considerable amount of work related to gasification and conversion. Hualu and Donghua have less work to handle. This project has a large scale of 1.8 million tons of methanol and 400,000 tons of ethylene glycol, but the production volume of coal-based olefins has not been disclosed. The projects in Yulin should be launched step by step again.
