Abstract: The invention relates to a hydrogen plant for producing a hydrogen-comprising gas product comprising—a reformer system comprising at least one heat-recuperating reformer reaction unit (5) or a reformer system comprising two or more reformer units (5,22) in parallel, wherein at least one of said parallel reformer units (5) is present in the radiant section (12) of the reformer system, and at least one reformer unit (22) is located outside the radiant section (12) of the reformer system; —a unit (8) configured to obtain hydrogen product gas; —a carbon dioxide capture unit; the hydrogen plant further comprising a passage way configured to feed a hydrogen-comprising gas stream to the radiant section. The invention further relates to a process for producing a hydrogen-comprising gas product.

Abstract: The invention is directed to a method for heating a process gas in a top or bottom fired reformer, a method for improving the temperature spread over a top or bottom fired reformer, and to a top or bottom fired reformer wherein these methods can applied. This can be achieved by the lane flow rate of at least one outer tube lane being different from the lane flow rate of at least one inner tube lane.
