Pressure Swing Adsorption (PSA) from Air Liquide Engineering & Construction is used to recover and purify hydrogen from a variety of hydrogen-rich streams. The technology relies on differences in the adsorption properties of gases to separate them under pressure, and is an effective way of producing very pure hydrogen.

Xintao 5A Molecular Sieve for hydrogen production, is a special molecular sieves for hydrogen production by pressure swing adsorption. It has the characteristics of large adsorption capacity, fast adsorption and desorption rate, and high mechanical strength, which is beneficial to the long-term stable operation of customer equipment or products.

Hydrogen Production Processes

The feed gas for PSA can be crude hydrogen from various sources including steam methane reforming, partial oxidation, cryogenic purification, methanol plant purge gas, ethylene off-gas, styrene off-gas, gasification and ammonia plants.

In the PSA process, hydrogen is pressurized in the feed tower, recovered and purified after adsorption and filtration, and the adsorbed impurities are removed by reducing the pressure.

The most advanced adsorbent is widely selected as the filter sieve bed in the hydrogen production machine. Xintao 5A special molecular sieve is used by a large number of hydrogen production machines. It greatly optimizes the hydrogen recovery rate and productivity and reduces customer costs.
