Blue hydrogen process and plant

A plant for producing a hydrogen product from a hydrocarbon feed, said plant comprising:

• a reforming unit, said reforming unit being arranged to receive a hydrocarbon feed and convert it to a stream of syngas;
• a shift section arranged to receive the stream of syngas from the reforming unit and shift it, thereby providing a shifted syngas stream;
• a hydrogen purification unit, arranged to receive said shifted syngas stream and separate it into a high-purity H2 stream as said hydrogen product, and CO2-rich off-gas stream;
• and
• a CO2-removal section for removal of CO2 from the CO2-rich off-gas stream to form a CO2-product stream and a CO2-depleted off-gas stream, and wherein said plant is arranged for recycling said CO2-depleted off-gas stream or a portion thereof, at least to the feed side of the reforming unit,
• wherein the plant further comprises at least one fired heater arranged to pre-heat said hydrocarbon feed prior to it being fed to the reforming unit, and wherein said plant is arranged to feed at least a part of the CO2-rich off-gas stream from said hydrogen purification unit, and/or at least part of said CO2-depleted off-gas stream as fuel for said fired heater,
• wherein the CO2-removal section comprises two or more CO2 separation units selected from the group consisting of an amine wash unit, a CO2 membrane, a CO2-PSA, a cryogenic separation unit and combinations thereof, and
• wherein the two or more CO2 separation units may be the same type or different types of units.
