Improved Hydrogen Recovery by Pressure Swing Adsorption PSA Process

Pressure swing adsorption (PSA) processes are widely used for the production of high purity hydrogen from the hydrogen-rich feedstock, such as coke oven gas, biogas, and Chlor-alkali tail gas.

After the purification process, high purity product hydrogen can be used for a variety of applications. It is very economical and the efficiency of the whole system will be much higher.

Performance

Application

• Hydrogen purification from water gas and semi water gas
• Hydrogen purification from shift gas
• Hydrogen purification from pyrolysis gases of methanol cracking and ammonia cracking
• Hydrogen purification from off-gas of styrene, refinery reformed gas, refinery dry gas, purge gases of synthetic ammonia or methanol, coke oven gas.
• Hydrogen purification from other sources of hydrogen-rich gases
