Pressure swing adsorption hydrogen extraction device
Device name: pressure swing adsorption hydrogen extraction device
Installation scale: 4000Nm³/h
Device customer: Dongying Jiahao Chemical Co., Ltd.
Process principle:
After the hydrogen-containing (H₂) mixed gas enters the adsorption tower of the pressure swing adsorption (PSA) device, the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with the pressure, and the raw gas is adsorbed when pressurized The impurity in the adsorbent and the difficult-to-adsorb component (hydrogen) are output as a product from the outlet end of the adsorption bed. During decompression, the adsorbed impurity component is desorbed and desorbed, and the adsorbent is regenerated at the same time. At least four adsorbent beds are used for cyclic operation. Realize continuous output of product hydrogen.
Raw gas:
methanol cracking gas, ammonia cracking gas, methanol tail gas, formaldehyde tail gas
Shift gas, refined gas, hydrocarbon steam reformed gas, fermentation gas, polysilicon tail gas
Semi-water gas, city gas, coke oven gas
Dry gas cracking in refineries, tail gas reforming in refineries
Other gas sources containing H₂
Technical index:
Raw gas:
Applicable pressure: 0.4~4.0MPa (gauge pressure)
Applicable temperature: normal temperature
The output product of this device: H₂
H₂ purity: 98~99.999% (V ), produced according to different uses and requirements of users
H₂ yield: 80~98%
System resistance drop P: 0.05~0.1MPa
output temperature: normal temperature
Note: H₂ yield is related to raw material composition, pressure and product H₂ purity.
