    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 recovered CO2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR).

    摘要： According the present invention, an oxygen enriched gas is generated by adsorbing and removing nitrogen gas from air with an oxygen concentrating apparatus which conducts the steps of (1) pressurizing one of the adsorption cylinders by directing the compressed air; (2) removing the oxygen enriched gas from said one of the adsorption cylinders to the output conduit; (3) reducing the pressure in said one of the adsorption cylinders by directing the oxygen enriched gas into one of the other adsorption cylinders to increase the pressure in the one of the other adsorption cylinders; (4) evacuating the internal gas out of said one of the adsorption cylinders; and (5) increasing the pressure in said one of the adsorption cylinders by directing the oxygen enriched gas into said one of the adsorption cylinders from one of the other adsorption cylinders in which the pressure is decreased in step (3).

    摘要： The present invention is a gas separation method using a plurality of adsorption columns packed with an adsorbent. A cycle including a series of steps (adsorption, first pressure reduction, second pressure reduction, desorption, scrubbing, and repressurization) is repeated in each adsorption column. In the adsorption step, a gas mixture (G1) is introduced into a column (A) so as to cause the adsorbent to adsorb unnecessary components, and a product gas (G2) is led outside of the column (FIG. 3A). In the first pressure reduction step, the internal pressure of the column (A) is reduced by lead-out of a gas (G3) (FIG. 4A). In the second pressure reduction step, the internal pressure of the column (A) is further reduced by lead-out of the gas (FIG. 4B). In the desorption step, the unnecessary components are desorbed from the adsorbent and purged from the column (A) (FIG. 4C). In the scrubbing step, introduction of the gas (G3) and purging of the gas (G4) are performed simultaneously (FIG. 5A). In the repressurizing step, the internal pressure of the column (A) is raised by introducing the gas (G3) (FIG. 5B). The gas (G3) that is led out from the column (A) during the first pressure reduction step is introduced into the column (C) during the scrubbing step (FIG. 4A), and the gas (G3) that is led out from the column (A) during the second pressure reduction step is introduced into the column (C) during the repressurizing step (FIG. 4B).
