摘要： The present invention generally relates to vacuum pressure swing adsorption (VPSA) processes and apparatus to recover carbon dioxide having a purity of approximately ≧90 mole % from streams containing at least carbon dioxide and hydrogen (e.g., syngas). The feed to the CO2 VPSA unit can be at super ambient pressure. The CO2 VPSA unit produces three streams, a H2-enriched stream, a H2-depleted stream and a CO2 product stream. When the CO2 VPSA unit is installed between an SMR/shift reactor and a H2 PSA unit, hydrogen recovery is expected to be increased by extracting CO2, thereby increasing hydrogen partial pressure in the H2 PSA feed. The stream from the CO2 VPSA unit, normally used as fuel, is recycled as feed to increase CO2 recovery. The recovered CO2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR).

摘要： The strongly adsorbed component of a gas mixture is produced in enhanced purity and yield by novel PSA cycles. The basic steps of the cycles include an adsorption vessel prepressurization step, a cocurrent nonadsorbed gas production step, a cocurrent purge step with strongly adsorbed gas product and a countercurrent depressurization step which produces the strongly adsorbed gas product that is used in the cocurrent purge step. In addition to the basic steps, a first depressurization equalization step precedes or follows the cocurrent purge step and a corresponding first pressurization equalization step follows the countercurrent depressurization step. The cycle optionally includes one or two depressurization equalization steps before the cocurrent purge step and one or two corresponding pressurization equalization steps after the first pressurization equalization step.

摘要： The present invention generally relates to vacuum pressure swing adsorption (VPSA) processes and apparatus to recover carbon dioxide having a purity of approximately ≥80 mole percent from streams containing at least carbon dioxide and nitrogen, such as the gaseous products of combustion (i.e. flue gas). The feed to the CO 2 VPSA can be at superambient pressure. The CO 2 VPSA unit produces a CO 2 product stream. The process cycle generates a high-pressure product stream that can be used to generate power for compressing the feed stream. The recovered CO 2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR). BACKGROUND OF THE INVENTION Many industrial operations employ combustion of fuel. Examples include kilns, incinerators, glassmaking furnaces, coal-fired power plants, and the like. Combustion of fuel produces streams of gaseous combustion products that comprise at least carbon dioxide, usually accompanied by nitrogen and one or more of oxygen, oxides of nitrogen and/or sulfur, and carbon monoxide. It would be desirable to provide economically beneficial processes and apparatus for CO 2 recovery. It would further be desirable for such processes and apparatus to be more efficient and easier to use relative to the prior art.

摘要： The present invention relates to a method for the combined production of hydrogen and carbon dioxide from a hydrocarbon mixture, in which the hydrocarbon mixture is reformed to produce a syngas which is cooled, then enriched with H 2 and CO 2 , optionally dried, and treated in a PSA hydrogen purification unit to produce hydrogen, the PSA offgas being treated to capture the CO 2 and to supply an offgas. This offgas is again treated to supply a stream enriched with H 2 and CO 2 which is returned to the PSA, where it constitutes a second feed distinct from the main feed.

摘要： A method of pressure swing adsorption (PSA) for producing a gas stream enriched in a compound X from a feed gas stream, implementing at least 2 adsorbers, each adsorber being subjected to a pressure cycle having a high pressure and a low pressure and comprising the following successive steps: a) adsorption at the high pressure of the cycle, producing the gas stream enriched in compound X, b) depressurisation to the low pressure of the cycle, producing at least a part of an elution gas, c) elution at the low pressure by means of the elution gas, d) repressurisation to the high pressure, characterised in that: the pressure cycle has a phase time corresponding to the duration of a pressure cycle divided by the number of adsorbers, and the pressure of the pressure cycle located between the high pressure and the low pressure of the pressure cycle is modified so as to keep the phase time of the PSA equal to or within ± 5% of the nominal phase time, corresponding to the phase time of the PSA in design conditions, during at least a part of the range of variation of the operating conditions.
