Abstract: The specification describes a method of retrofitting a chemical plant which initially comprises a hydrotreating section and a steam reforming section, the method involving introducing a tail-gas treatment which is arranged to accept tail-gas from the steam reforming section and generate a crude H2 stream which is used at least in part to provide fuel for the fired reformer within the steam reforming section. The specification also describes an integrated hydrogen and hydrotreatment plant which incorporates a tail-gas treatment unit, and a process for producing hydrogen and carrying our hydrotreatment using the plant.

Abstract: A method of producing hydrogen from a hydrocarbon feedstock is provided. Wherein, at least a portion of a fuel stream comprises a superheated ammonia stream. And, at least: a first portion of a hydrogen-rich stream is combined with a shifted syngas stream prior to introduction into a pressure swing adsorber, a second portion of the hydrogen-rich stream is combined with the fuel stream prior to introduction into a steam methane reformer, and/or a third portion of the hydrogen-rich stream is combined with a hydrocarbon containing feedstock stream and a steam stream prior to introduction into a feed pre-heater. Heat integration between the ammonia vaporization and superheating steps is employed to cool process streams to minimize and even eliminate a dedicated cryogenic refrigeration system.

Abstract: A purpose of the present invention is to provide a pumpless high-pressure hydrogen supply system capable of supplying high-pressure hydrogen to a fuel cell vehicle, etc., when needed without using a compressor or the like, and a method for the system. The present invention relates to a high-pressure hydrogen supply system that obtains a mixed gas of hydrogen and carbon dioxide by dehydrogenation of formic acid using a complex catalyst, separates the hydrogen therefrom, and supplies the hydrogen at a pressure of 5 MPa or more. By obtaining the mixed gas at a pressure of 5 MPa or more by dehydrogenation and cooling the mixed gas by a separator while maintaining this pressure at 0.4 MPa or more, gas components other than hydrogen are phase separated as liquids or solids and removed. The separated hydrogen is raised in purity by pressure fluctuation adsorption, continuously sent to a pressure accumulator, and stored at a pressure of 70 MPa or more.
