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： An autothermal reactor and method for producing synthesis gas in which a heated oxygen containing stream is expanded into a mixing chamber to entrain a hydrocarbon containing stream to form a reactant stream without reaction of the oxygen and hydrocarbon contents of the streams. The reactant stream is reacted in a series of sequential catalytic reaction zones to react the hydrocarbon and oxygen contained in the reactant stream to form the synthesis gas. The sequential catalytic reaction zones are configured such that an initial partial oxidation reaction occurs that is followed by endothermic reforming reactions having ever decreasing temperatures. The sequential catalytic reaction zones in which the endothermic reforming reactions occur contain a precious metal catalyst supported on ceramic supports that have successively greater surface areas to compensate for the temperature decrease while remaining stable and without a transform in state.

摘要： A three column cryogenic rectification system for producing at least one of oxygen and nitrogen employing a medium pressure column which is operating at a pressure between the operating pressures of the higher and lower pressure columns, and which receives an air feed which is at a lower pressure than the air feed to the higher pressure column. The medium pressure column processes oxygen-enriched liquid from the higher pressure column and is reboiled by a fluid taken from below the top of the higher pressure column.
