Abstract
Abstract 1,108,746. Gas scrubber. PRAT-DANIEL S.A. 5 April, 1965 [3 April, 1964], No. 14433/ 65. Heading B1R. A gas scrubber comprises a vessel 2 containing a body of liquid and divided by walls 8 and 10 into chambers 38' and 38, chambers 38' communicating through openings in a wall 5 with an inlet 7 for the gas to be scrubbed and chambers 38 containing in operation an upwardly moving mass of liquid droplets entrained by the gas as it passes through a screen formed of perforated plates 12 and 13 arranged as shown above the level of the liquid at the bottom of chambers 38. Liquid is removed from the scrubbed gas in an eliminator 20 and leaves at 4, separated liquid returning to the vessel 2. Chambers 38' have inclined baffles 16 entering gas passing below the baffles.
