Abstract: A plant and process for producing a hydrogen rich gas are provided, said process including the steps of: steam reforming a hydrocarbon feed into a synthesis gas; shifting the synthesis gas and conducting the shifted gas to a hydrogen purification unit, subjecting CO2-rich off-gas from the hydrogen purification unit to a carbon dioxide removal in a low temperature CO2-removal section and recycling CO2-depleted off-gas rich in hydrogen to the process. A drying unit upstream the CO2-removal section is provided, under the addition of regeneration gas produced in the plant and process.

Abstract: A system is provided for reforming a hydrocarbon feedstock. The system comprises: first prereformer units and first preheating unit arranged upstream a bayonet tube steam methane reformer. The system is arranged to provide a temperature of the heated partially-reformed process stream at the inlet of the bayonet tube steam methane reformer of at least 600° C. and a temperature of the gas at the bottom of the bayonet steam methane reformer tubes of at least 800° C. This arrangement allows higher bayonet tube inlet temperatures, with reduced risk of increased metal dusting. A process is also provided for reforming a hydrocarbon feedstock in the system of the invention.

Abstract: A chemical plant is provided which comprises an air separation section (ASU), a reformer section, a water-removal section and a refrigerated separation section. A first feed of atmospheric air is separated in the ASU to produce a refrigerant stream. A hydrocarbon feed is converted to a first syngas stream in the reformer section. Water is removed from the first syngas stream and at least a portion of the resulting dried first syngas stream is separated it into at least a product stream, and a by-product stream; by means of the refrigerated separation section. Importantly, the refrigerated separation section is cooled by a refrigerant stream (e.g., nitrogen) from the ASU. A process for producing a product stream, using the plant, is also provided.

Abstract: A plant and process for producing hydrogen, comprising: a primary reforming unit arranged to receive a hydrocarbon feed, such as natural gas, and comprising: a combustion section comprising a catalyst suitably for steam methane reforming, and one or more burners for providing heat for said steam methane reforming, for thereby generating a synthesis gas stream and a flue gas stream, and a convection section comprising heat exchangers for thereby generating a cooled flue gas stream; wherein said one or more burners are arranged to receive a preheated combustion air stream and a preheated fuel gas stream derived from a downstream hydrogen purification unit which is arranged to receive at least a portion of said synthesis gas stream, for thereby generating a hydrogen-rich stream and an off-gas stream; and in which the fuel gas stream is a portion of said hydrogen-rich stream i.e. first fuel gas stream, or a gas stream, i.e. second fuel gas stream, resulting from combining at least a portion of said off-gas stream and a portion of said hydrogen-rich stream. The invention relates also to method of retrofitting an existing plant for producing hydrogen.

Abstract: A plant and process for producing a hydrogen rich gas are provided, said process comprising the steps of: reforming a hydrocarbon feed in an autothermal reformer thereby obtaining a syngas; shifting said syngas in a shift configuration including a high temperature shift step; removal of CO2 in a CO2-removal section by amine wash thereby forming a hydrogen rich stream, a portion of which is used as low carbon hydrogen fuel, as well as a CO2-rich gas and a high-pressure flash gas stream. The high-pressure flash gas stream is advantageously integrated into the plant and process for further improving carbon capture.
