On May 13, 2023, the 60,000 m3/h shale gas-based hydrogen production plant owned by Chongqing Huafeng Chemical Co., Ltd., for which Southwest Chemical Engineering Research and Design Institute Co., Ltd. (referred to as “Southwest Institute”) was responsible for overall project management, started up successfully, producing high-quality hydrogen on the first attempt. The project was commissioned on May 8, with hydrogen production starting on May 13. It is the first unit to come online among the various units of Chongqing Huafeng’s Phase 6 expansion project, marking a successful start for the smooth commissioning of the entire Phase 6 expansion At present, the facility is operating smoothly, with all key performance indicators reaching leading levels in China; the hydrogen produced has been integrated into the plant’s hydrogen pipeline network. Subsequently, the load will be increased gradually until it reaches the designed load of 60,000 m3/h. On March 10, 2022, Southwest Chemical Research and Design Institute Co., Ltd. signed an EPC general contract for the \"1.15 million tons/year adipic acid expansion project (Phase VI) – 60,000 m3/h natural gas-based hydrogen production facility\" with Chongqing Huafeng Chemical Co., Ltd. The previous batches of adipic acid production facilities at Chongqing Huafeng were all equipped with natural gas-based hydrogen production units. The project utilizes the natural gas steam reforming process and pressure swing adsorption hydrogen separation process, which are proprietary technologies of the Southwest Research Institute; the institute also provides the key steam reforming catalysts, desulfurization agents, adsorbents, as well as specialized programmable valves for pressure swing adsorption. The overall performance of this facility is at the leading level in China and among the best in the world; it represents a typical facility for large-scale hydrogen production from natural gas. Chongqing Huafeng’s Phase 6 project includes a cyclohexanol plant with an annual production capacity of 320,000 tons, a ** plant with an annual production capacity of 200,000 tons, and an adipic acid plant with an annual production capacity of 255,000 tons. Upon completion of Phase 6, Chongqing Huafeng’s adipic acid production capacity will reach 1.15 million tons per year. Project Overview: Project Name: 1.15 million tons/year adipic acid expansion project (Phase 6). Project investor and constructor: Chongqing Huafeng Chemical Co., Ltd. Project investment estimate and funding source: The total investment is estimated at 2,755 million yuan, with funds coming from bank loans and self-financing; the actual investment amount and construction period will be determined based on the actual conditions after the project is implemented. Project construction period: Estimated at 24 months. The progress of project implementation will be adjusted as appropriate in light of market demands, operational conditions, and comprehensive evaluations by the board of directors, with disclosures made in accordance with relevant laws and regulations. Process technology: The cyclohexene method is planned to be used for the production of adipic acid. Project location: Baitao Chemical Industrial Park, Fuling District, Chongqing City.
