International Classification:
F25J 3/00
US Classification:
62617
Abstract:
Apparatus and process for producing a hydrogen-containing product stream and a carbon monoxide-containing product stream from a crude synthesis gas produced in a syngas production unit. Carbon dioxide is removed from the process gas by a non-cryogenic means and the hydrogen-containing product stream is separated from the process gas in a pressure swing adsorber. Residual gas from the pressure swing adsorber is passed to a cryogenic separation unit where the cryogenic separation unit separates the residual gas stream into the carbon monoxide-containing product stream, a hydrogen-enriched stream, a methane-enriched stream, and a carbon monoxide-containing intermediate stream by cryogenic fractionation. At least a portion of the hydrogen-enriched stream is recycled to the pressure swing adsorber.

International Classification:
C01B 3/34, C10J 3/46
US Classification:
48197R, 481981, 481983, 423650, 423651, 423652, 423655, 252373
Abstract:
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.

International Classification:
C01B 3/26
US Classification:
423652, 252373
Abstract:
A method for generating hydrogen and/or syngas in a production facility where little or no export steam is produced. Most or all of the steam produced from the waste heat from the process is used in the steam-hydrocarbon reformer. Reformed gas is passed to a pressure swing adsorption system for Hpurification. In the method, COis removed from the pressure swing adsorber residual gas prior to recycling the residual gas to the reformer for use as feed and as fuel. Plant efficiencies using the method and prior art-type methods are compared.

Abstract:
A process and apparatus for producing a hydrogen-containing gas in a reformer where a furnace, which is independent of the reformer, heats the effluent from a prereformer prior to reacting the prereformer effluent in the reformer. The prereformer effluent may be heated in a heat exchange tube in the furnace where the heat exchange tube is positioned in the furnace to preclude direct radiation from any flames in the furnace thereby preventing local overheating of the heat exchange tube and preventing carbon formation in the heat exchange tube. Fuel and oxidant gas may be introduced into the furnace with significant excess oxidant gas, having a stoichiometric ratio of 1. 8 to 2. 8 for controlling the temperature of the heat exchange tube.

International Classification:
C01B 3/40
US Classification:
481987, 48197 FM
Abstract:
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 at least two shift reactors. The shifted mixture is separated to form a COproduct stream, the hydrogen-containing product gas, and a pressure swing adsorption tail gas. A fuel gas comprising the pressure swing adsorption tail gas and a supplemental fuel are combusted in the reformer furnace. The Hconcentration in the fuel gas ranges from 35 volume % to 70 volume % and the supplemental fuel provides 5% to 15% of the firing rate.
