摘要： A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent; feeding the rich solvent to at least one inter-stage cooler; recovering the rich solvent and feeding the rich solvent to a regeneration column; separating the carbon dioxide from the rich solvent and recovering the carbon dioxide to form a lean solvent; feeding the lean solvent to the absorber column. The improvement is realized by one of feeding steam to the flue gas; feeding steam to the absorber column after introduction of amine solvent; feeding the flue gas stream to a demister before feeding to the absorber column or increasing the lean solvent inlet temperature into the absorber column.

摘要： The integrated processes of the dry reforming or partial oxidation upstream of the carbon nanotube-producing reactor are described allowing the carbon monoxide to be produced on an as-needed basis, negating the need to transport carbon monoxide to the production site or store large quantities of carbon monoxide on-site. The apparatuses allowing to carry out such integrated processes are also provided. Carbon dioxide emissions may be eliminated from the carbon nanotube production process. This may be achieved by recycling the carbon dioxide byproduct and mixing it with the feed to the partial oxidation process.

摘要： Synthesis gas comprising hydrogen, water, carbon monoxide, carbon dioxide, and hydrocarbons is produced by contacting a gasified hydrocarbon feedstock and an oxidant in a partial oxidation reactor under at least 95% carbon monoxide selective, low hydrocarbon conversion conditions wherein the temperature, pressure, and flow rate conditions in the reactor yield synthesis gas having less than about 2% carbon dioxide. After being cooled, the synthesis gas is separated into high purity hydrogen, high purity carbon monoxide and a hydrogen-carbon monoxide gas mixture by pressure swing adsorption followed by cryogenic distillation or by two or more pressure swing adsorption steps.

摘要： A process for separation of a gas mixture containing three components, e.g. a mixture comprising hydrogen, carbon monoxide and carbon dioxide produced by steam reforming a hydrocarbon, by pressure swing adsorption is disclosed. In one embodiment of the process, the gas mixture is sequentially passed through first and second adsorptive regions each of which adsorbs a second component more strongly than a first component but less strongly than a third component, a first fraction enriched in the first component is withdrawn from the downstream end of the second region, introduction of gas mixture to the first region is stopped and the second region is closed to the first region, a second fraction enriched in the second component is withdrawn first from the upstream end of the second adsorptive region while passing gas mixture enriched in the third component into the first region from its upstream end and then from the downstream end of the first region, and withdrawing a third fraction enriched in the third component from the upstream end of the first region. The separation process is also applicable to other gas mixtures such as a mixture of hydrogen, argon, methane and nitrogen commonly available as ammonia plant purge gas from which ammonia has been removed.

摘要： A strongly adsorbed gas is recovered from a multicomponent gas mixture comprised of the strongly adsorbed gas, a flammable gas component and oxygen by repeating as essential steps (a) cocurrently passing the gas mixture through a bed of adsorbent which preferentially adsorbs the strongly adsorbed gas, thereby producing a nonadsorbed gas product stream that is depleted in the strongly adsorbed gas, (b) terminating the flow of multicomponent gas mixture into the bed and depressurizing the bed by countercurrently withdrawing a strongly adsorbed gas-enriched product stream from the bed and (c) countercurrently repressurizing the bed with the multicomponent gas mixture.

摘要： The present invention is directed to a method for recovering argon from a feed mixture comprising argon, carbon monoxide, carbon dioxide, nitrogen, and hydrogen which comprises the steps of (a) purifying the feed mixture to remove contaminants, (b) compressing the purified feed mixture to a separation pressure, and (c) passing the compressed purified feed mixture through a pressure swing adsorption system to separate carbon monoxide, carbon dioxide, and all or most of the nitrogen from the mixture as adsorbed products and to produce an argon-rich fraction as a non-adsorbed product. The argon-rich fraction from step (c) may be further purified by passing the fraction to a cryogenic fractional distillation system to separate hydrogen and any remaining nitrogen from the fraction as a distillate product and to produce a pure argon product. In a second and third embodiment, the invention is directed to a method for recovering argon from a feed mixture comprising argon, carbon monoxide, carbon dioxide, nitrogen, and oxygen, wherein oxygen is removed from the argon-rich fraction exiting the pressure swing adsorption system in step (c) by passing the fraction to a second pressure swing adsorption system before or after further purification of the fraction in a cryogenic fractional distillation system.
