Quality supervision review completed for the backpressure generator set of Anqing Shuguang coal-to-hydrogen project Author/Source: Coal Chemical Industry Information Network Date: July 20, 2020 Clicks: 160 With the close attention of the various management levels at Anqing Shuguang Chemical Co., Ltd., as well as the personal arrangement and guidance of Wu Yuefeng, vice president and chief engineer of Donghua Technology, the commissioning work of the backpressure generator set for the Anqing Shuguang coal-to-hydrogen project, which was undertaken by Donghua Technology on a turnkey basis, has been fully completed. A quality supervision review was carried out from July 10 to 12 in the Shuguang Chemical Park. On the afternoon of the 10th, the first meeting for supervision and inspection prior to the full-scale startup test run of the Anqing Shuguang backpressure generator set was held in the conference room on the third floor of the office building in the Shuguang Chemical Park. The Provincial Power Quality Supervision Station, the project owner Anqing Shuguang, the general contractor Donghua Technology, the construction company Deer Company, the supervision company Anhui Wanwei Company, and the commissioning company Anhui Xinli Company attended this meeting. At the meeting, the various responsible parties, including those in charge of construction, general contracting, construction work, supervision, and commissioning, presented reports on the project quality materials one after another. After carefully reviewing the presentation materials submitted by each unit, the expert team raised corresponding questions, which were then answered by those units. On the 11th, the team of experts, in accordance with their respective areas of expertise and responsibilities, conducted a thorough inspection of the construction progress in areas such as the boiler room, deaeration room, turbine room, and sewage treatment station, focusing on aspects like civil engineering, boilers, turbines, electrical systems, automatic control systems, materials, and water treatment. They also checked the records kept by various responsible parties throughout the construction process in the archives. On the morning of the 12th, the final meeting was held in the conference room on the third floor of the office building. The expert team presented their reports on the quality inspection and supervision activities one after another. Cao Yueping, the head of the inspection and supervision team, read out the experts’ opinions, outlining the issues that needed to be addressed before the unit’s trial operation, including 9 issues related to quality practices and 13 issues related to the physical quality of the unit. The construction and installation work for this project has been essentially completed in accordance with the design requirements, and all necessary inspection certificates are available ； Only after the issues identified have been rectified by the construction unit in collaboration with the relevant parties, approved by the supervision unit, and reported in writing to the power quality inspection station for verification, can the entire unit be started up and put into operation. The construction, general contracting, construction execution, supervision, and commissioning units carefully listened to the experts’ suggestions and committed to addressing and improving the issues. The successful completion of this quality supervision and review process marks a crucial step forward in the commissioning of Anqing Shuguang back-pressure generator sets. Once operational, these turbine units will be able to handle at least half of the plant’s electricity demand, which will help improve the plant’s economic efficiency. For Donghua Technology, this also marks the complete end of the Anqing Shuguang coal-to-hydrogen project. In August 2016, the feed was successfully introduced into the project’s gasification furnace, resulting in the production of high-quality methanol. This marks the completion of the entire production process for this project; it now enables the supply of hydrogen to Sinopec Anqing Branch once its major maintenance is over and operations resume. It also ensures a supply of hydrogen and syngas for the 250,000 tons per year butyl octanol production project in the Shuguang Chemical Park. The total estimated investment for the coal-to-hydrogen project is 2.4 billion yuan. It involves the use of a new pressure-water-coal slurry gasification technology to build large-scale gasification units, with a designed capacity of 85,500 standard cubic meters per hour of usable gas. This project is part of the funding initiatives aimed at promoting the development of strategic emerging industries in Anhui Province, and it also serves as a supporting project for the transformation and upgrading efforts carried out by Shuguang Group. The coal-to-hydrogen project of Anqing Shuguang Chemical Co., Ltd. is located on the south side of Yongjin Road in Anqing High-Tech Zone, between Huanhu Road and Xiahong Road. Using raw coal as a raw material, the project supplies 44,800 Nm3/h of hydrogen to the refining units at Anqing Petrochemical, and 22,500 Nm3/h of syngas to the butyl octanol production units; it also produces 67,300 tons of methanol and 12,500 tons of sulfuric acid per year. At present, the main construction of the project has been completed, and the relevant production equipment has been installed. The 3 coal-fired fluidized bed boilers with a capacity of 220 tons per hour have been replaced by 3 coal-fired fluidized bed boilers with a capacity of 150 tons per hour, and a corresponding differential pressure power generation system has been built as well.
