High Performance Hydrogen Production From Methanol Hydrogen Psa Unit
Beijing Huafu 550Nm3/h Hydrogen Production From Methanol
Technology Application
Using methanol as raw material, crude hydrogen (mainly CO2, H2, and trace CO, CH4) is produced by steam cracking process, and then purified by pressure swing adsorption technology to obtain hydrogen with purity meeting the requirements of users.
The raw methanol and raw desalted water are premixed at a certain ratio, pressurized by metering pump, preheated, gasified and superheated, and then enter the reactor. Under the action of catalyst, the reaction is carried out to generate crude hydrogen. After heat exchange, the heat is recovered, cooled, and then enter the pressure swing adsorption device for final purification.
PSA purification
The PSA purification unit applies 6-2-2 PSA (6 absorbers, 2 for feeding, 2 times pressure equalization and desorption).In each cycle, the adsorption tower need to go through adsorption, pressure drop, blow-down, purging, pressure boost, etc.
