200Nm3 PSA Hydrogen Plant From Methanol Hydrogen Generation Unit
Qianan 200Nm3 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.
catalytic conversion reaction
Under certain temperature and pressure and the effect of catalyst, methanol vapor mixture in the reformer have a gas phase catalytic reaction, complete the methanol reforming and CO shift reaction at the same time.
The process is designed to complete the conversion of chemical reaction, transforming gas mainly containing hydrogen and carbon dioxide.
Benefits for customers in hydrogen plant design
Our technology allows for flexible utilization of feedstocks, and designs may be optimized for lowest operating expenditure (OPEX), highest efficiency or lowest total lifecycle cost. Different degrees of modularization and standardization can be applied to meet the project requirements. For all plant designs excelling availability and reliability remains a prime focus. Here customers benefit from Air Liquide’s vast experience in operation with its own large fleet of steam reforming plants.
