摘要: Disclosed herein is a method and system for separating carbon dioxide (CO2) from a CO2 containing gas stream containing water vapor and additional impurities, for example, nitrogen, oxygen, sulfur oxides, nitrogen oxides, and mercury. The CO2 is captured by subjecting the CO2 gas feed stream to a temperature swing adsorption step. The temperature swing adsorption step comprises an adsorption step for producing a substantially dry carbon dioxide-depleted stream, and an adsorbent regeneration step comprising heating the adsorbent bed to produce a substantially water vapor-free carbon dioxide stream. Moisture from the gas stream containing CO2 is optionally removed by pressure swing adsorption, temperature swing adsorption, membrane separation, or absorption prior to CO2 capture.

摘要: For separating carbon dioxide (CO2) from a gas stream, a substantially moisture free gas stream is produced using a first temperature swing adsorption (TSA), a first pressure swing adsorption (PSA), a first vacuum swing adsorption (VSA), membrane separation, a first absorption, or any combination thereof. CO2 is captured from the substantially moisture free gas stream and substantially dry CO2 depleted stream is produced using a second TSA, a second PSA, a second VSA, or a second absorption with a non-aqueous solvent with or without a chemical reaction. Adsorbents and/or absorbents used during moisture removal are regenerated using the substantially dry CO2 depleted stream. Purifying a gas stream containing CO2 and impurities includes producing a stream substantially depleted of moisture and impurities using a physical or reactive adsorbent, thermally regenerating the adsorbent to produce a stream substantially enriched in impurities, and removing impurities from the stream substantially enriched in impurities.
