Sinopec Hydrogen Recovery Unit Methanol Steam Reforming For Hydrogen Production
Sinopec Zhongyuan Petrochmeical 250Nm3/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.
Process flow of methanol reforming is as follows:
Technical indexes
Capacity:250Nm3/h
Purity:99% ~ 99.999%
Features and advantages:
Mature process technology and safe and reliable operation.
Wide source of raw material and large processing scale.
Advanced recovery technology of thermal energy and low consumption
of production energy.
