The demand for hydrogen purity continues to increase, and the pressure swing adsorption (PSA) hydrogen production market has great development potential.

Pressure swing adsorption (PSA) is a process that separates different gases in the same adsorbent based on different adsorption capacities or diffusion rates. Pressure swing adsorption is a new gas adsorption and separation technology. Hydrogen separation and purification mainly includes three processes: distillation, PSA and membrane separation. Under the premise of cost and scope of application, PSA is the preferred process for obtaining high-purity hydrogen.

Hydrogen is a clean and renewable energy. Under the background of carbon neutrality and carbon peak strategies, hydrogen has become increasingly widely used in medicine, petrochemicals, metallurgy, fuel cells, transportation, electronics, food, glass, etc. Multiple areas. With the expansion of application fields, the market’s requirements for hydrogen purity and utilization are also increasing. Against this background, the PSA hydrogen production market has attracted increasing attention.

According to different sources of raw materials, PSA hydrogen production can be divided into chemical by-product raw gas, waste gas raw gas, etc., among which chemical by-product raw gas is the main source. The PSA hydrogen production unit is an important unit of large refineries and coal chemical plants. In recent years, with the development of coal chemical, petroleum and other industries, the output of PSA hydrogen production units has continued to increase. Globally, PSA hydrogen production technology or equipment supply companies include UOP Company of the United States, LINDE Company of Germany, Air Liquide, Southwest Research Institute of Chemical Industry, Tianke Co., Ltd., Peking University Pioneer, Sichuan Yalian Hydrogen Energy Technology, etc.

According to the “2023-2028 Pressure Swing Adsorption (PSA) hydrogen production industry market in-depth research and investment prospect forecast analysis report》 shows that PSA hydrogen production has multiple advantages such as low energy consumption, simple process, and high product purity. In recent years, with the expansion of hydrogen use scale and advancement of process technology, the global PSA hydrogen production market has continued to grow, reaching US$600 million in 2022. about. Globally, the PSA hydrogen production market is mainly distributed in North America, Europe and the Asia-Pacific region. It is expected that from 2023 to 2028, as related devices are put into production and the demand for high-purity hydrogen is released, the global PSA hydrogen production market will further grow and will be in 2028. It exceeds US$1 billion annually.

The PSA hydrogen production process can be divided into adsorption, pressure equalization, reverse release, regeneration, final upgrading and other links. In the adsorption link, the adsorbent is the core of the PSA hydrogen production reaction. At present, the adsorbents used in PSA hydrogen production are mainly divided into zeolite, Carbon molecular sieves, activated carbon, metal organic frameworks (MOFs), etc. In recent years, thanks to the continuous development of adsorbents and continuous optimization of processes, the purity of PSA hydrogen production has been continuously improved. Currently, the purity of PSA hydrogen production has exceeded 99.999%.

Industry analysts said that PSA hydrogen production has multiple advantages such as low energy consumption and simple process. It is carbon neutral and reaches carbon peak. Under the strategic background, the expansion of hydrogen application scope and the increase in hydrogen purity requirements will drive the rapid development of the PSA hydrogen production market. PSA can be used to produce high-purity hydrogen. In the future, with in-depth research on adsorbents, continuous optimization of processes, and successive production of devices, the scale of PSA hydrogen production will continue to expand.
