摘要: A process for producing a hydrogen-containing product gas with reduced carbon dioxide emissions compared to conventional hydrogen production processes. A hydrocarbon and steam are reformed in a reformer and the resulting reformate stream is shifted in one or more shift reactors. The shifted mixture is scrubbed to remove carbon dioxide to form a carbon dioxide-depleted stream. The carbon dioxide-depleted stream is separated to form a hydrogen-containing product gas and a by-product gas. A portion of the hydrogen containing product gas is used as a fuel in the reformer and a portion of the by-product gas is recycled back into the process. The process may optionally include reforming in a prereformer and/or an oxygen secondary reformer.

摘要: A method for generating hydrogen and/or synthesis gas in a production facility where little or no export steam is produced. Most or all of the high pressure steam produced from the waste heat from the process is used in the steam-hydrocarbon reformer with little or no steam export. The method uses oxygen enhanced combustion which may involve oxygen lancing and/or oxygen-enrichment. Plant efficiencies using the method and prior art-type methods are compared.

摘要: Method and apparatus for maintaining even heat distribution to each of the tubes contained in a down-fired induced draft furnace by eliminating external atmosphere disturbances such as wind from influencing furnace operation. The top of the furnace is isolated from receiving ambient air except through a central path which controls both rate and direction of air flow.

摘要: A hydrogen production method that integrates a catalytic steam reformer and a gasifier. Hydrogen is generated in a catalytic steam reformer at a high production rate or design capacity. The catalytic steam reformer is then turned down to a fraction of design capacity while a gasifier produces the needed hydrogen. During the turned down state of the catalytic steam reformer, more of a hydrogen-containing stream formed from gasifier effluent is fed to the catalytic steam reformer as a feed thereby reducing the flow rate of feedstock required for the catalytic steam reformer in the turned down state. Optionally, hydrogen mixtures from the catalytic steam reformer and gasifier are fed to one or more adsorbers for hydrogen purification and adsorber effluent is fired as fuel in the steam reformer furnace to provide a majority of the heat needed for the reforming reaction.
