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 COconvective 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.

Systems and methods for producing hydrogen with integrated capture of carbon dioxide

A hydrogen feed stream comprising one or more impurities selected from the group consisting of nitrogen, argon, methane, carbon monoxide, carbon dioxide, oxygen, and water, is purified using a cryogenic temperature swing adsorption (CTSA) process with high overall recovery of hydrogen. The waste gas from regenerating the CTSA may be used to improve the performance of upstream hydrogen processing steps.

Method for producing high purity hydrogen

A hydrogen feed stream comprising one or more impurities selected from the group consisting of nitrogen, argon, methane, carbon monoxide, carbon dioxide, oxygen, and water, is contacted with liquid hydrogen in a cryogenic wash column (CWC) process that produces pure hydrogen with high overall recovery. The waste liquid stream leaving the CWC may be used to improve the performance of upstream hydrogen processing steps.
