PSA hydrogen gas purification device "H2-PSA"

PSA hydrogen gas purification device "H2-PSA"

Decomposing city gas, methanol, and others to produce hydrogen gas! High-purity hydrogen gas can also be recovered and refined.

We would like to introduce our PSA hydrogen gas purification system, 'H2-PSA'. Hydrogen gas has a significantly lower adsorption capacity compared to other gases, which allows for the purification of high-purity hydrogen gas from various mixed gases. Thanks to the use of adsorbents with excellent adsorption capacity, the system is compact. The installation of a pre-filter that operates in the same process as the adsorption tank enables the recovery and purification of hydrogen gas from dirty gases such as COG at high efficiency and low cost without any special pretreatment. 【Features】 ■ Produces hydrogen gas by decomposing city gas and methanol ■ Capable of recovering and purifying high-purity hydrogen gas from various hydrogen-containing gases ■ Compact design due to the use of adsorbents with excellent adsorption capacity ■ Installation of a pre-filter that operates in the same process as the adsorption tank ■ Enables high-efficiency and low-cost hydrogen gas recovery and purification without special pretreatment *For more details, please refer to the PDF document or feel free to contact us.
