Sichuan Tianyi won the bid for the super-large PSA hydrogen production project required for the 1.8 million tons per year ethylene glycol production facility of Shaanxi Coal Group Yulin Chemical Company. Author/Source: Special Gas Network; Date: 2019-07-01; Clicks: 47. Pressure swing adsorption for hydrogen production is an important process for large-scale hydrogen purification, and it serves as a key component in large refineries and coal chemical plants. In recent years, with the development of China’s petroleum refining industry and modern coal chemical industry, the demand for hydrogen in such facilities has been increasing continuously. Recently, Haohua Chemical Technology Group Co., Ltd. (formerly Sichuan Tianyi Technology Co., Ltd.) successfully won the bid for the super-large PSA hydrogen production project required as part of the 1.8 million tons per year ethylene glycol production facility at Shaanxi Coal Group Yulin Chemical Company. The 1.8 million tons per year ethylene glycol production project of Shaanxi Coal Yulin Chemical Company is part of Shaanxi Coal Group’s “Demonstration Project for the Production of New Chemical Materials through the Differential Utilization of Coal”. Using coal as raw material and employing coal slurry gasification technology, this project goes through processes such as gasification, shift reaction, low-temperature methanol washing, PSA hydrogen production, and deep-cold separation of CO, in order to ultimately produce ethylene glycol. Among them, PSA hydrogen production is an important part of the entire process. It is understood that the PSA hydrogen production unit associated with this project has a total raw gas processing capacity of 570,000 Nm3/h, with a total hydrogen production capacity of 480,000 Nm3/h. Once completed, it will be the largest coal-to-hydrogen PSA plant in the world to date. It represents another significant advancement in China’s PSA hydrogen production technology, following the ultra-large-scale 280,000 Nm3/h PSA hydrogen production project built by Shenhua in Ordos in 2008. It is reported that the “Demonstration Project on the Utilization of Coal at Different Quality Levels to Produce New Chemical Materials” in Yulin, Shaanxi Coal Group, is a large-scale coal conversion project that was given priority in the planning and development by Shaanxi Coal Group during the 13th Five-Year Plan period. This project is a pilot initiative by Shaanxi Coal Group to make use of the resources available in Yulin in order to develop a high-end industrial cluster focused on the production of chemical new materials through the differentiated utilization of coal. It has been designated as a key project for the deep processing of coal, and it is currently the largest coal chemical project under construction in the world. Haohua Technology stated that the successful bid for this PSA project once again establishes the company’s and Southwest Chemical Research and Design Institute’s leadership in PSA technology on a global scale. It also further fulfills the company’s mission of serving the world through low-carbon, environmentally friendly technologies and clean energy solutions.
