Views: 11. Recently, the integrated demonstration project for the clean utilization of high-sulfur coal in Shanxi’s Lu’an region has carried out tests on the methanol circulation system and the propylene refrigeration system in accordance with the planned comprehensive trial operation schedule. The successful joint commissioning of the methanol circulation and propylene refrigeration systems in the 180-project purification unit indicates that the conditions for pilot production of a single series in this purification unit are now basically in place. 　　 The combined operation of the methanol cycle and the propylene refrigeration system is primarily used to assess the stability and sensitivity of the system’s control valves, as well as the material balance. It also involves flushing the pipelines and equipment to ensure that they are unobstructed, clean, and airtight ； Further examine the construction quality of moving and stationary equipment, as well as the reliability of their technical performance. 　　 To ensure the safe and orderly progress of the combined operation, Lu’an Coal-based Clean Energy Company carried out meticulous organization and coordination. A plant commissioning team composed of specialized personnel made thorough preparations. During the combined operation phase, after completing the water circulation process and nitrogen drying of the system, the process engineers filled the system with methanol to initiate its circulation. Subsequently, after ensuring the airtightness of the propylene system, performing nitrogen purging, and filling it with propylene, the crew started the propylene refrigeration compressor unit, thereby establishing a complete circulation in the propylene refrigeration system. The temperature of methanol in the low-temperature methanol washing unit gradually decreased, reaching -20°C before eventually dropping to -40°C. Based on the hot standby of the deoxygenated water station and Transform Unit II series, the combined trial run of the methanol circulation and propylene refrigeration systems was successful. The project has entered the final stage of testing. On October 20, Lu’an Coal-based Clean Energy Company held the second meeting regarding the environmental impact assessment for the completion of Phase 1 of the 180 project, and specific arrangements were made for the related environmental assessment tasks. Xiao Yaning, vice president of Lu’an Group, along with heads of relevant departments within the group, key members of Lu’an Coal-based Clean Energy Company, as well as representatives from Guohuan Jianbang Company, which is responsible for preparing the assessment report, and project contractors such as Zhongke and Huisheng, attended the meeting. At the meeting, Xiao Yaning, deputy general manager of Lu’an Group, emphasized that since the environmental impact assessment for Project 180 was approved in March 2016, thanks to the joint efforts of all parties involved, the first phase of this project has been largely completed and it is now entering the final stage of testing. Environmental protection is crucial for the future development of Project 180; on one hand, all participating units must strictly adhere to the requirements regarding the completion timeline, be aware of the situation, and attach great importance to it. On the other hand, the various inspection teams need to improve their working mechanisms, hold regular meetings, fully assume their responsibilities, identify and address any shortcomings, and ensure strict supervision. Make every effort to turn Project 180 into a model environmental protection project in the coal chemical industry. On September 15, the Shanxi Provincial Work Safety Supervision and Administration Bureau issued a response to the application submitted by Shanxi Lu’an Mining (Group) Co., Ltd. for the review of the safety facility design for its integrated demonstration project aimed at the clean utilization of high-sulfur coal for oil production, power generation, and heating. The approval states that the design of the safety facilities for this project is generally in line with the provisions of the \"Measures for the Safety Supervision and Management of Hazardous Chemicals Construction Projects\" (Order No. 45 issued by the State Administration for Work Safety), and it is approved to use the \"Special Report on the Design of Safety Facilities for the Integrated Demonstration Project for the Clean Utilization of High-Sulfur Coal for Oil, Chemicals, and Heat Production by Shanxi Lu’an Mining (Group) Co., Ltd.\" as an important basis for the detailed design and construction of the safety facilities for this construction project. 　　 With the implementation of the new Work Safety Law, **the safety management requirements for the chemical industry are becoming increasingly stringent. As a major model project for transformation in Shanxi Province, the integrated demonstration project for the clean utilization of high-sulfur coal in oil, chemical, and thermal applications serves as a pioneer in safety management within the chemical industry, with safety requirements that far exceed **the standard. The approval of the design review for the project’s safety facilities signifies that all safety procedures required during the construction of the 180 project have been met in a legal and compliant manner, providing a solid foundation for achieving the ambitious goal of starting up the plant and beginning oil production this year. The integrated demonstration project for the clean utilization of high-sulfur coal for oil, chemical, and thermal applications in Shanxi Lu’an is located in the Wangqiao Industrial Park, Xiangyuan County, Changzhi City, Shanxi Province. It was invested and constructed by Shanxi Lu’an Mining (Group) Co., Ltd., and it represents a key project focused on during the 12th Five-Year Plan period, as well as a crucial initiative for Shanxi Province’s industrial structure transformation. Using coal with high sulfur, high ash content, and high ash melting point as raw material, the project employs the SHELL dry powder gasification process to achieve a technological breakthrough with the first powder gasifier having a capacity of 3,000 tons per day. The project utilizes the iron-based high-temperature slurry-bed F-T synthetic oil technology developed by CAS, which possesses complete independent intellectual property rights. Phase 1 of the project involves the construction of a pilot industrial facility for iron-based slurry-bed Fischer-Tropsch synthesis and oil product processing, with an annual production capacity of 1 million tons of oil products and chemicals. The facility will also include a 108 MW waste heat power generation unit. The main components of the facility include gasification units, purification units, Fischer-Tropsch synthesis units, oil product processing units, waste heat power generation units, as well as various supporting utility systems ； Phase II involves the construction of a 800,000 tons per year industrial demonstration facility for the processing of cobalt-based FTO wax.
