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.
