Abstract

1,213,158. Gas scrubbing process. RUHRCHEMIE A.G. 28 Dec., 1967 [26 Jan., 1967], No. 58863/67. Heading B1R. Gases from the sintering or wet-processing of phosphate rock enter a U-shaped gas scrubber at 11 and pass downwardly through limb 1 containing axially disposed spray nozzles 2 and then pass upwardly through limb 3 and are given a rotary motion 'by vanes (not shown) on the surface of an axially disposed body 4 above which a liquid spray 5 is arranged. Scrubbed gases are withdrawn at 12 after passing through a droplet eliminator 13 and sludge-containing liquid is withdrawn at 10. Liquid may also be introduced into limb 1 at 16 to prevent accumilation of dust adjacent the inlet. Calcium hydroxide may be added to the scrubbing liquid for the removal of fluorine compounds from the gases and the amount of added hydroxide is such that the pH of the liquid separated in eliminator 13 is about 8.
