After hydrogen (H2) mixed gas enters the pressure swing adsorption (PSA) unit, various impurities in the feed gas are selectively adsorbed in the bed by various adsorbents in the adsorption tower, and the non-adsorbable component, hydrogen, is exported from the outlet of the adsorption tower. After the adsorption is saturated, the impurities are desorbed and the adsorbent is regenerated.
Features:
1. Choosing the most reasonable process route according to the factories' actual conditions, with high gas yield and stable product quality.
2. The adsorbent with high efficiency has strong selective adsorbability for impurities, strong adsorbent and long lifespan more than 10 years.
3. Configuration of special programmable control valves, valve lifespan is over 10 years, drive form can meet the oil pressure or pneumatic.
4. It has a perfect control system and is suitable for all kinds of control systems.
PSA hydrogen plant applicable feed gas: Methanol cracking gas, ammonia cracking gas, methanol tail gas and formaldehyde tail gas Synthetic gas, shift gas, refining gas, hydrocarbon steam reforming gas, fermentation gas, polycrystalline silicon tail gas Semi-water gas, city gas, coke oven gas and orchid tail gas Refinery FCC dry gas and refinery reforming tail gas Other Gas Sources Containing
H2 Purity: 98%~99.999%
The PSA Technology also can be used in:
1. CO2 Separation and purification (PSA - CO2)
To recycle pure CO2 is recycled from CO2-rich gas mixture. Material gases include: such as exhaust gas of lime kiln, fermentation gas, converted gas, natural mine gas and other gas sources with CO2. The purity of the recycled CO2 reaching can reach 98~99.99%.
2. CO Separation and Purification (PSA - CO)
To recycle pure CO is recycled from CO-rich gas mixture. Material gases include: such as semi-water gas, water gas, blast furnace gas of cuprammonia regenerated gas, yellow phosphorus tail gas and other gas sources with CO. The purity of the recycled CO can reach the purity of CO reaching 80~99.9%.
3. CO2 Removal (PSA - CO2 Removal)
Remove CO2 from converted gas, which is applied for decarbonization of synthetic ammonia and methanol production.
