Abstract
This invention is a process and system for providing hydrogen at a high level of reliability from a gasification system by integrating it with SMR. Carbonaceous feedstock such as petroleum coke or coal or biomass is gasified to co-produce SNG, fuel gas, hydrogen, power and steam in conjunction with hydrogen production through steam methane reforming. Carbon dioxide may also be recovered in this process. The integrated schemes are designed in a way that maximizes the reliability of production of high value products such as hydrogen through gasification and minimizes the impact of high natural gas prices on hydrogen production by SMR.
