Hydrogen by Dual Feedstock / Multi Feedstock Plants

Under normal market situation, the most efficient feed for a low OPEX hydrogen generation plant is natural gas. However, in some world regions the supply is insecure due to network pressure drops or natural gas price is extremely high as only LNG is available. Alternative feedstocks then could be MeOH, LPG or naphtha. To not entirely loose the chance on operating the plant at low OPEX, a firm decision to fix the plant design on one of the liquid feeds is undesirable.
In such situation, a dual feedstock or even multi feedstock plant may be a feasible decision for the client. Even though CAPEX will be higher compared to a single feedstock plant, the plant will be advantageous in terms of increased on-stream time by overcoming loss of production caused by feed cut off.
By combining various process steps, such as evaporation and pre-reforming of feedstocks, these feedstocks can be handled then by an adapted steam reforming plant operating normally on natural gas.
