Title: SYSTEM AND PROCESS FOR SYNTHESIS GAS PRODUCTION
Abstract:
The invention relates to a hydrogen production system. The system comprises: -optionally, one or more gas conditioning stages chosen between the following stages: a hydro- genation stage, a desulfurization stage,and a prereforming stage, arranged to receive a hydro- gen enriched hydrocarbon stream and to process said hydrocarbon feed stream into a condi- tioned hydrocarbon stream, -a steam reformer unit downstream the one or more gas conditioning units, -a steam addition line arranged to add steam upstream the steam reformer unit, a hydrogen membrane unit comprising a hydrogen permeable membrane and being arranged to allow at least a part of a reformed stream and a hydrocarbon feed stream to pass on different sides of a hydrogen permeable membrane, so that hydrogen passes from the reformed stream into the hydrocarbon feed stream, thereby forming said hydrogen enriched hydrocarbon stream, and -a separation unit downstream the first side of the hydrogen membrane unit, where the separa- tion unit is arranged to separating the reformed stream exiting the first side of the hydrogen membrane unit into a hydrogen product gas and an off-gas. The invention also relates to a corresponding process.
