252373, 423650, 423652
Abstract:
According to the present invention, hydrogen/carbon monoxide synthesis gas (also called syngas) is produced by injection of a second reactant stream into a hydrocarbon reformer at a location between the entry and discharge ends of the reformer. The second reactant stream can contain: carbon dioxide; a mixture of carbon dioxide and hydrocarbon; a mixture of hydrocarbon and steam, a mixture of carbon dioxide and steam; or a mixture of carbon dioxide with hydrocarbon and steam. All or part of the mixtures containing hydrocarbon and steam can be prereformed hydrocarbon in steam.
Wastewater is passed sequentially through an anaerobic treating zone and an oxic treating zone, followed by separation from the treated liquor of a dense sludge containing activated biomass, a least part of which is recycled to provide the activated biomass employed in treating the influent wastewater. Of the part of the sludge so recycled a minor portion is introduced into the anaerobic treating zone for admixture with the wastewater influent and the remaining major portion is introduced into the oxic treating zone, into which oxic zone oxygen-containing gas is admitted to effect oxygenation of the contents of that zone.

Abstract:
Substantially pure hydrogen and high purity carbon monoxide are produced and recovered from a methane-rich gas composition, such as natural gas, by subjecting such composition to steam reforming in a first stage at relatively mild conditions, followed by secondary oxidative reforming of the thus obtained primary reformate effecting conversion of residual methane therein to carbon oxides. The secondary reformate, comprised chiefly of hydrogen, CO, and CO. sub. 2, is subjected to a novel sequence of operations for separation of these individual components. CO. sub. 2 is first removed by solvent absorption, followed by selective adsorption for separation of CO from the CO. sub. 2 -freed gas mixture with attendant recovery of hydrogen product of 98. sup. + % purity as an unsorbed effluent. Trace to small amounts of undesired carbon monoxide in the thus recovered hydrogen product can be converted by catalytic methanation.

International Classification:
F25J 308 B01D 5322
US Classification:
62 23
Abstract:
The present invention involves a process for recovering hydrogen from a feed gas mixture comprising hydrogen and at least one other component. The feed gas mixture is initially separated in a membrane separation unit to produce a hydrogen-rich stream and a hydrogen-lean stream. The hydrogen-lean stream is subsequently treated in a cryogenic separation unit to remove a portion of the non-hydrogen components and produce a hydrogen-enriched stream. The hydrogen-enriched stream from the cryogenic separation unit is recycled and combined with the feed gas mixture to the membrane separation unit.
Integrated Reformer Process For The Production Of Carbon Black

International Classification:
C01B 3162 C09C 148
US Classification:
423450
Abstract:
Carbon black is produced from a pyrolyzed hydrocarbon wherein pyrolysis is effected by combusting a synthesis gas containing hydrogen and carbon monoxide. The synthesis gas is produced from reforming a hydrocarbon fuel, wherein the reformation is heated by combusting carbon black effluent tail gas or indirect heat exchange of the hot tail gas.

International Classification:
F25J 300
US Classification:
62 17
Abstract:
High purity methane is recovered from a fuel gas stream containing the same in admixture with mainly nitrogen and carbon dioxide, by first removing the carbon dioxide by selective adsorption in a PSA system and separating the remaining nitrogen from the methane by cryogenic distillation, the rejected nitrogen being employed for purging the CO. sub. 2 -laden adsorbent beds of the PSA system. Cyclic regeneration of the sorbent-laden bed may entail nitrogen purge with or without including a carbon dioxide rinse, or the nitrogen purge of the sorbent-laden bed may be used in combination with pressure let-down by gas withdrawal into one or more companion beds.

Abstract:
Crude ammonia synthesis gas is obtained by primary steam reforming of a hydrocarbon gas mixture rich in methane, such as natural gas, followed by secondary reforming of the primary reformate with added air and shift conversion of the contained CO to CO. sub. 2. The shift conversion product is first freed of contained CO. sub. 2 by selective absorption in a novel PSA unit having an integrated B section for removal of remaining impurities such as carbon monoxide and methane, thereby providing as product a gas stream comprised of hydrogen and nitrogen in approximate 3:1 molar ratio accompanied by a small amount or argon derived from the air stream used in the secondary reforming step. Alternative embodiments are disclosed for removal of CO from the gas stream, before its entry into the NH. sub. 3 conversion operation; any residual CO that might have slipped thorugh the absorbent bed of the B section is converted to CH. sub. 4.

Abstract:
Nitrogen is economically recovered from the flue gas evolved in a hydrocarbon steam reforming furnace by hydrogenation of free oxygen therein and removal of carbon dioxide and other minor impurities from the flue gas by pressure swing adsorption with recovery of high purity nitrogen is unsorbed effluent. The process is utilized to highest advantage in the production of ammonia syngas wherein natural gas or other hydrocarbon feed is subjected to steam reforming in a fuel-fired furnace. The nitrogen obtained by purification of the flue gas is combined with the purified hydrogen separated from the reformate providing the syngas for conversion to ammonia. In a preferred embodiment, the steam reforming is carried out in two stages, the first stage being performed in a conventional fuel-fired steam reforming furnace to which a major portion of the fresh hydrocarbon feed is charged. The hot effluent from this first reforming stage is employed as the heating medium to support reforming of the remaining minor portion of the fresh feed by heat exchange therewith.
