摘要: The present invention is directed to a method and system of purifying hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption. The adsorbed impurities can be removed from the adsorbent by increasing the temperature, reducing the pressure, or a combination of both.

摘要: Organic sulfur compounds contained in refinery off gas streams having either high ort low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.

摘要: An Apparatus for purifying a feed stream containing carbon dioxide in which the feed stream, after having been compressed and dried, is partly cooled and then used to reboil a stripping column. Thereafter, the feed stream is further cooled and expanded to a lower operational temperature of the stripping column. A carbon dioxide product stream composed of the liquid column bottoms of the stripping column is expanded at one or more pressures to generate refrigeration, then fully vaporized within the main heat exchanger and compressed by a compressor to produce a compressed carbon dioxide product. Refrigeration is recovered in the main heat exchanger from a column overhead stream extracted from the stripping column within the main heat exchanger either directly or indirectly by auxiliary processing in which carbon dioxide is further separated and optionally recycled back to the main compressor used in compressing the feed stream.

摘要: Carbon dioxide-containing feed stream such as flue gas is treated to produce a high-purity carbon dioxide stream by a series of steps including removing SOx and NOx with activated carbon, carrying out subambient-temperature processing to produce a product stream and a vent stream, and treating the vent stream by pressure swing adsorption or by physical or chemical absorption to produce a product stream which is recycled to the feed stream.

摘要: An apparatus for generating electrical power in which a synthesis gas stream generated in a gasifier is partially oxidized, expanded and thereafter, is combusted in an oxygen transport membrane system of a boiler. The combustion generates heat to raise steam to in turn generate electricity by a generator coupled to a steam turbine. The resultant flue gas can be purified to produce a carbon dioxide product.
