Development trends of pressure swing adsorption oxygen production technology, pressure swing adsorption oxygen production equipment manufacturers tell you

       Pressure Swing Adsorption (PSA) Oxygen Generation EquipmentManufacturers believe that with the steady and rapid development of China's economy, the country's steel, non-ferrous metallurgy, chemical, kiln energy saving, environmental protection, glass, and paper industries are constantly upgrading and innovating production processes. Process optimization and capacity expansion have led to a growing demand for oxygen. The huge demand for oxygen has driven technological advancements in domestic industrial oxygen production equipment. Traditional cryogenic air separation technology, pressure swing adsorption (PSA) oxygen generation technology, and membrane separation technology have all made certain progress. Due to the low product purity, membrane separation technology limits its adaptability. China's cryogenic technology and pressure swing adsorption technology have made great progress in recent years. In particular, after breakthroughs in the domestic production of new lithium-based adsorbents and the development of radial adsorption towers, PSA oxygen generation technology has been widely applied in China and has been widely recognized by users.

　　Pressure Swing Adsorption (PSA) Oxygen Generation EquipmentManufacturers believe that in recent years, with the development of permanent magnet motors and the optimization of oxygen production processes, foreignPSA oxygen production energy consumption has dropped to below 0.3 kWh/nm3, the scale of dual-tower oxygen production has exceeded 6000 nm3/h, the cost of PSA oxygen production has further decreased, and the scale of oxygen production has increased year by year, further promoting the expansion of the application areas of this technology.

　　Pressure swing adsorption (PSA) oxygen generation equipment manufacturers believe that China's pressure swing adsorption oxygen generation technologyFromResearch began in the late 1980s, and only small-scale industrial installations emerged in the early 1990s. The adsorbent used in the initial oxygen generation device was CaA molecular sieve adsorbent, and the process was the PSA process. FromThe beginning ofFrom 20 Nm3/h, 50 Nm3/h, and 100 Nm3/h to the end of the 1990s, the scale of PSA oxygen production in China was only 1000 Nm3/h, and the electricity consumption of pure oxygen exceeded 0.5 kWh/Nm3. Some products in the early stages of development of domestic PSA oxygen generators had problems such as high noise and failure rate of Roots blowers, especially high failure rate of switching valves, and easy pulverization of molecular sieves. Many units, especially in the steel industry, launched PSA oxygen generation equipment based on the characteristics of being short, flat, and fast. Due to the large workload of the equipment and high maintenance costs, it was replaced with cryogenic separation equipment, leaving a negative impact on the public that the equipment could not operate for a long time, the maintenance was excessive, and it could not be scaled up. The gap with the advanced international level at that time was obvious.

　　Pressure Swing Adsorption (PSA) Oxygen Generation EquipmentManufacturers believe that with the stable production of high-efficiency lithium-based adsorbents, the research and development of radial bed adsorbers, and the solution of key problems in PSA oxygen generation technology such as reliable high-frequency large-diameter butterfly valves, the scale of domestic PSA oxygen generation technology has increased year by year, oxygen electricity consumption has gradually decreased, and the reliability of the equipment has steadily improved. The equipment specifications have also developed from the initial single-set dual-tower oxygen generation device scale of less than1000 nm3/h to the current 6000 nm3/h. After multiple towers are connected in parallel, the scale reaches more than 30000 nm3/h, the unit oxygen production electricity consumption is reduced to below 0.32 kWh/nm3, and the annual operating rate of the oxygen production device reaches more than 98%.
