Process and device for the production of a gas that contains hydrogen from hydrogen sulfide

A process for the production of hydrogen from a hydrogen sulfide feedstock, comprising a stage for heating feedstock (1) in a heating zone (2, 5) to a suitable temperature so as to produce a hot gas (6) that contains hydrogen and elementary sulfur, whereby this heating is carried out at least in par...

Beschreibung
Zusammenfassung:	A process for the production of hydrogen from a hydrogen sulfide feedstock, comprising a stage for heating feedstock (1) in a heating zone (2, 5) to a suitable temperature so as to produce a hot gas (6) that contains hydrogen and elementary sulfur, whereby this heating is carried out at least in part by an external heat source and a stage for rapid cooling of the hot gas thus obtained, by mixing with a fluid (8) by means of at least one mixer (7), preferably an ejector, so as to obtain a gaseous effluent (9). The mixing time is less than 20 milliseconds. Elementary sulfur (11) is separated from this effluent and the hydrogen is recovered. Application for the elimination of hydrogen sulfide and the production of hydrogen.
