Malaysia SAB 1000Nm3/H Hydrogen Manufacturing Plant From Methanol

Malaysia SAB 1000Nm3/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.

gas-liquid separation

The process is further separation of very few water in the conversion gas, avoid moisture into the PSA section and increase the adsorption agent service life.

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.

Process flow of methanol reforming is as follows:

Technical indexes:

purity: 99%~99.999%

Capacity: 25~100000Nm3/h

Yield :≥90%
