<p>High-purity Ar was selectively sepd. by pressure swingabsorption(PSA) method from the air. Sepg. process comprises (1) inject air into 1st absorption appratus (AA) contg. column(filling with 3 carbon molecules), (2) obtg. a high-purity oxygen and midpurity Ar by PSA from air, (3) inject a former Ar into 2nd AA contg. column(filling with 2 carbon molecules) continuously, (4) circulating of desorptive gas from 2nd AA into 1st inlet of AA. Absorption pressure is 0.3- 10kg/cm2G; Desorption pressure is below 760 Torr.</p> |
