Evaluation of Qinghua Phase I demonstration project for producing 1.375 billion m3 of coal-to-natural gas per year begins Author/Source: Huahua Network – Coal Chemical Industry Date: July 17, 2023 Clicks: 35 On July 11, an on-site evaluation team organized by the China Petroleum and Chemical Industry Federation arrived at Xinjiang Qinghua Energy Group Co., Ltd. to conduct a five-day on-site assessment of the Qinghua Phase I demonstration project, which is capable of producing 1.375 billion m3 of coal-to-natural gas per year. The on-site assessment will play a positive role in promoting the initiation and construction of the company’s second-phase project. Wang Xiujiang, deputy director of the Science and Technology Department of the China Petroleum and Chemical Industry Federation, presided over the meeting to launch the on-site assessment. At the meeting, Zhang Laiyong, the head of the assessment team, outlined the tasks to be carried out during the assessment period ； The responsible persons from the relevant departments of Xinjiang Qinghua Energy Group Co., Ltd. introduced the assessment and calibration plan, as well as the construction, operation, and usage of the facilities. Following on-site discussions, the expert group established a plan for on-site assessment and calibration. Xinjiang Qinghua’s project for producing 5.5 billion cubic meters of coal-based gas per year was the first coal deep-processing demonstration project approved by the National Development and Reform Commission during the 12th Five-Year Plan period. Phase 1 of the project was launched in April 2009, with formal design work beginning at that time, and construction started in May 2010. All preparatory work for the tests was completed in August 2013. On December 27, 2013, the finished natural gas was officially integrated into the West-to-East Gas Pipeline Project Phase II network. Zhao Hongguang, the chief engineer of the coal-to-gas division at Xinjiang Qinghua Energy Group Co., Ltd., explained that the approval for Qinghua’s 5.5 billion cubic meter coal-to-gas project entails construction in two phases: Phase 1 requires an investment of 1.375 billion yuan, while Phase 2 will cost around 4 billion yuan. The results of the assessments conducted on Phase 1 serve as a factual basis for planning the operation of Phase 2, thereby enabling faster progress in the construction of this natural gas project. Since its commissioning until June 25, 2023, the first-phase demonstration project of Xinjiang Qinghua Energy Group Co., Ltd., with an annual production capacity of 1.375 billion m3 of coal-to-natural gas, has produced a total of 8.8835 billion m3 of coal-to-natural gas. It is reported that this calibration represents a comprehensive assessment of various aspects of the first-phase project, including its design work, construction and installation quality, production operations, and management level. It mainly focuses on determining the production capacity for the first phase, and verifies the progress of the two industrialization demonstration projects (4.0 MPa coal crushing pressurized fixed-bed gasification technology and high-efficiency sewage treatment and reuse technology), as well as the performance parameters of domestically produced methanation catalysts.
