How does Hydrogen Generation by Steam Reforming work?
Steam reforming of natural gas, LPG or naphtha (feedstocks) with subsequent purification is the most economic and thus most common process for hydrogen generation and serves 95% of the world’s hydrogen demand.
Basic process steps:
The feedstock is desulphurized, mixed with steam and converted to synthesis gas in the top fired reformer furnace using nickel catalyst. The synthesis gas is cooled down in the heat recovery section and subsequently fed to the high temperature CO-conversion reactor followed by cooling and HYDROSWING PSA purification.

The majority of Hydrogen is produced by steam methane reforming (SMR). Hydrogen is generated from a hydrocarbon (e.g. natural gas) and water at high temperatures in catalytic reformers. Typically, the Hydrogen is purified by using a PSA unit. About 95 % of the total global Hydrogen is used at the site where it is produced.
In most cases, the steam is generated inside the hydrogen plant by cooling down the hot process gas and the fluegas from the steam reformer.
At Mahler-plants the ignition of the burners is done automatically from the control container/room, no manual ignition by an operator is necessary. Mahler designs tailor-made and standard plants and has already built more than 4500 plants worldwide.
From a reasonable and economical point of view the operating pressure of the Hydrogen-PSA-unit, as part of a hydrogen generation plant as well as for a stand-alone plant, should be between 10 and 30 bar(abs).

Our plants are used worldwide. Especially for Russia, Belarus and Kazakhstan we are able to provide our plants with all necessary TR certificates and declarations for the import and operation in the Custom Union. Our HYDROFORM-C plants are equipped with a serial declaration according TR CU 010/2011 (MD), TR CU 004/2011 (LVD) and TR CU 020/2011 (EMC), valid until beginning of 2025. Certificates or declarations according TR CU 032/2013 for all pressure vessels as well as a TR CU 012/2011 certificate for the entire equipment placed inside areas with potentially explosive atmospheres are also part of our scope of supply.
