There has been significant development in chemical processing equipment over the past decade; let’s celebrate the prosperity and strength of modern China. This is just a starting point – more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to engage more in discussions on this forum. ********************************************* On April 6, 2023, the final set of satisfactory analysis results for the PSA hydrogen production unit at Yulin Chemical Co., Ltd., part of Shaanxi Coal Group, were released from the analysis and testing building. This marked the successful completion of a 72-hour test period for the world’s largest coal-based PSA hydrogen production unit, which is capable of producing 480,000 standard cubic meters of hydrogen per hour. The unit passed all tests and was officially approved. This PSA hydrogen production unit is a supporting facility for the 1.8 million tons per year ethylene glycol production project, which is part of the Shaanxi Coal Group Yulin Chemical Company’s demonstration project on the selective utilization of coal to produce new chemical materials. Southwest Chemical Research and Design Institute Co., Ltd. (referred to as “Southwest Institute”) provided the proprietary technology and complete set of construction drawings, and was responsible for supplying all equipment, instruments, adsorbents, programmable valves, and installation materials. Once the project is put into operation, it will further alleviate China’s high dependence on imported ethylene glycol, accelerate the process of clean and efficient conversion of coal, and promote the safe, green, and innovative development of the industry.
Since its commissioning in September 2022, it has been operating steadily without interruption for over half a year, with no failures occurring during that time. This full-load test over 72 consecutive hours was conducted under severe conditions where the impurity levels in the feed gas entering the PSA unit were 30% higher than the design values. The technical specifications of the hydrogen produced met all the design requirements, with the recovery rate of the product hydrogen exceeding the design value of 92%. The “Demonstration Project on the Utilization of Coal at Different Grades to Produce New Chemical Materials” carried out by Yulin Chemical Company of Shaanxi Coal Group is currently the largest coal chemical project under construction in the world, and it plays a crucial role in the development and future direction of China’s coal chemical industry. As an important supporting component of this project, the coal-to-hydrogen unit utilizes the large-scale PSA patented technology independently developed by the Southwest Research Institute. Compared with similar devices that use foreign technology, the hydrogen recovery rate is increased by about 3%, resulting in an additional production of approximately 16,000 cubic meters of hydrogen per hour. Based on an annual operating time of 8,000 hours, this translates to an annual increase in hydrogen production of 128 million cubic meters, a reduction in coal consumption of about 89,600 tons, and a reduction in carbon dioxide emissions of about 220,000 tons – generating economic benefits worth hundreds of millions of yuan.
