PLANT FOR HYDROGEN PRODUCTION

摘要

The present invention relates to a plant for performing a method for hydrogen production or for performing a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii).

主权项

1. A plant for hydrogen production according to the method comprising
(i) providing a gas stream comprising hydrogen and carbon monoxide; (ii) separating at least 70 vol. % of hydrogen from the stream by membrane separation wherein said separating consists of applying the said stream to a thin palladium-based membrane having a thickness of 1-3 μm and optionally applying an inert sweep gas downstream of the membrane, yielding a hydrogen-depleted stream; (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction; and (iv) optionally separating hydrogen from the stream resulting from step (iii); said plant comprising a reactor 110 for the production of syngas from hydrocarbons, wherein an outlet of the reactor 110 is connected to an inlet of a first separation module 101, 101A for hydrogen separation having an outlet for hydrogen and an outlet for a hydrogen-depleted stream, wherein the outlet for the hydrogen-depleted stream is connected to an inlet of a shift reactor 103 for water gas shift reaction.
