    Abstract: Product gas (Gpro) is separated from material gas (Gmat) by a PSA process utilizing a plurality of adsorption towers (A-C) each loaded with an adsorbent. The separation of the product gas (Gpro) is performed by repeating a cycle comprising an adsorption step, a decompression step, a desorption step, a cleaning step and a pressurization step. In the decompression step, remaining gas (Grem) as cleaning gas is introduced from one adsorption tower (C) to another adsorption tower (B). The amount of the remaining gas (Grem) introduced is 2 to 7 times the volume of the adsorbent loaded in the adsorption tower (B) as converted into volume at common temperature and under atmospheric pressure. To remove both of carbon monoxide and carbon dioxide from the material gas (Gmat) by a single kind of adsorbent, use is made of zeolite having a faujasite structure with a Si/Al ratio lying in a range of 1 to 1.5 and a lithium-exchange ratio of no less than 95%.

    Abstract: 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).

    Abstract: A process is provided for recovering oxygen-rich gas by enriching gaseous oxygen contained in crude gas by a single-tank PSA process which utilizes a single adsorption tower loaded with an adsorbent. A cycle is repeated including introducing crude gas into the adsorption tower, desorbing unnecessary components from the adsorbent, introducing washing gas into the adsorption tower for discharging the remaining gas from the adsorption tower, and raising the internal pressure of the adsorption tower. The desorbing includes recovering semi-enriched oxygen gas existing in the adsorption tower after finishing of the adsorption for retention in a recovery tank. The introduction of washing gas includes introducing part of the semi-enriched oxygen gas existing in the recovery tank into the adsorption tower as the washing gas. Raising the internal pressure includes introducing the rest of the semi-enriched oxygen gas retained in the recovery tank into the adsorption tower.

    Abstract: In a process of recovering oxygen-enriched gas by pressure swing adsorption with use of adsorbers (A, B) each packed with an adsorbent which selectively adsorbs nitrogen from a gas mixture mainly containing nitrogen and oxygen, recovery of remaining oxygen-enrich gas is fully carried out by pressure equalization between both adsorbers (A, B), and a vacuum pump (8) is always connected to either adsorber (A or B) for continuous evacuation of nitrogen. For this purpose, the pressure equalization between both adsorbers (A, B) is conducted at least in two steps wherein one adsorber (A or B) is pressurized, whereas the other adsorber (B or A) is pressurized, so that recovery of oxygen-enriched gas is possible until there is substantially no pressure difference between both adsorbers (A, B).
