Abstract
The present disclosure provides systems and methods for hydrogen production as well as apparatuses useful in such systems and methods, including steam generation systems and methods. Hydrogen is produced by reforming of a hydrocarbon in a plurality of reformers to achieve improved reforming efficiency. A CO2 convective reformer (CCR) and an oxygen secondary reformer (OSR) are used in series to convert hydrocarbon and steam to synthesis gas with substantially complete carbon capture. Steam generation is provided along separate pathways to provide separate steam streams of different composition.
Claims6
A steam generation system comprising:
- a reforming envelope configured with a heating line or series of lines for passage of heat source stream from a heat source;
- and
- a steam generation envelope comprising:
- a first steam generation pathway comprising a first water line or series of lines arranged for passage of water from a first water source to a first heat exchange train and passage of steam from the first heat exchange train to one or more steam turbines;
- and
- a second steam generation pathway comprising a second water line or series of lines arranged for passage of water from a second water source to a second heat exchange train and passage of steam from the second heat exchange train.
