摘要: A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal.

摘要: Systems and methods for producing synthetic gas are provided. The method can include gasifying a carbonaceous feedstock in the presence of an oxidant within a gasifier to provide a raw syngas. The raw syngas can be cooled within a cooler to provide a cooled syngas. The cooled syngas can be processed within a purification system to provide a treated syngas. The purification system can include a saturator adapted to increase a moisture content of the cooled syngas. The treated syngas and a first heat transfer medium can be introduced to a methanator to provide a synthetic gas, a second heat transfer medium, and a methanation condensate. At least a portion of the methanation condensate can be recycled from the methanator to the saturator.

摘要: Reformer and method for producing hydrogen and steam where steam is used for steam-assisted extraction of heavy hydrocarbons. Steam is injected into a hydrocarbon-containing reservoir. Hydrocarbons are extracted from the reservoir along with produced water. Hydrogen is produced in a catalytic steam hydrocarbon reformer. Combustion product gas from the reformer is used to generate wet steam in a once-through steam generator from produced water recycled from the reservoir. The wet steam is used for the steam-assisted extraction of heavy hydrocarbons. The reformer has a heat exchanger section including a first heat exchanger and a second heat exchanger downstream of the first heat exchanger. The second heat exchanger is suitable for processing the produced water by once-through steam generation and is suitable for mechanical cleaning. The reformer also has a first exhaust downstream of the second heat exchanger and a closeable second exhaust downstream of the first heat exchanger.

摘要: A process and a system are provided for producing and separating hydrogen and carbon dioxide from a hydrocarbon and steam. A hydrocarbon and steam are steam reformed and the reformed gas is shift reacted to produce a shift gas. Hydrogen is removed from the shift gas, and the hydrogen-depleted gas is reformed and shift reacted again to produce more hydrogen and carbon dioxide. The hydrogen and carbon dioxide are then separated.
