The sub stoichiometric combustion of hydrocarbons (NG, LPG) with subsequent conversion of CO to CO2 followed by removal of CO2 by means of Mono Ethanol Amine (MEA) is a well-established process for the generation of protective gas. Depending on customers’ demands the HN/HNX gas generation plants can deliver a protective gas with a hydrogen content between 1 vol.- % to 12 vol.-%.
Individual plant concepts to cover higher capacities and different hydrogen contents, as well as back-up systems to guarantee a continuous gas supply can be offered.
