Causes of Hydrogen Quality Dropping in Pressure Swing Adsorption Process in Hydrogen Production

The causes of hydrogen quality dropping in operation of the hydrogen production system by natural gas of Baosteel are analyzed.The commonly used ways to deal with hydrogen quality dropping are summarized.Through analysis of influence of mixture gas temperature on pressure swing adsorption(PSA) performance,it is found out that equipment and environment factors result in hydrogen quality dropping.The failures are eliminated after improvement.
