Abstract
526,542. Bromides and bromates. WILLIAMSON, A. T., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 18, 1939, No. 5512. [Class 1 (iii)] A process for absorbing bromine from gases containing it, e.g., from air blowing chlorinated brine, comprises treating the gas with an alkaline absorption liquor in a series of cyclically operated absorption towers, the flows of gas and liquor in the series as a whole being counter-current and in the towers either co- or counter-current, and reducing the back pressure of bromine exerted by the circulating liquor by employing in association with at least one tower such a volume of circulating liquor that the periodic time of circulation for that tower exceeds a time to move to = 5W/QL minutes (W being the total rate of absorption in kg. per minute and QL is the rate of liquor circulation in the tower in c. meters per min.) and/or by heating at least part of the circulating liquor associated with at least one tower, while the liquor is outside the tower, the liquor being cooled before it is again brought into contact with the gas. Preferably at least one tower at or near the end of the series has associated with it a volume of circulating liquor greater than the average volume per tower. The absorbing liquor may be a 3-12 per cent. aqueous solution of sodium carbonate, caustic soda or borax. In a typical example, illustrated by Fig. 1, the volume of liquid associated with each tower is 8 c.m., the liquor circulating rate being .278 c.m. per minute and the total rate of absorption is 0.164 kgs. per minute. The periodic time of circulation is 28.8 minutes, i.e., equal to 48.8 W/QL. Five towers only of a given efficiency are required compared with nine in the known process to absorb 97 per cent. bromine in the original gas and the total liquor volume is 40 c.m. In a further example (Fig. 2) each tower has 10 c.m. of liquor associated therewith and the liquor leaving tower No. 1 is heated to 60‹C. in the relay vessel and cooled to 20‹C. before its return to the tower. The periodic time of circulation in this case W is 36 mins., i.e., 61.4- and four towers only QL are necessary with a total liquor volume of 40 c.m.
