1,080,847. Chemical contact apparatus &c. RHONEPOULENC S.A. June 6, 1966 [June 9, 1965], No. 25033/66. Heading B1F. A reactor, suitable for carrying out reactions between a gas and a liquid or between liquids in concurrent or countercurrent flow from which vapour is given off, is divided into superimposed stages 8a, 8b and 8c by separating plates 7, each stage containing a bundle of vertical tubes 10 arranged slightly below the centre of the stage and forcing ascent tubes 13 and a central tube 14, and with pipes 11 extending through the plates 7 coaxial with the tubes 13 through which gas or vapour passes upwardly and a down pipe 12 extending to beneath the liquid level in the shape below. The passing upwardly of the gas or vapour causes the liquid to rise up tubes 13 so effecting circulation whatever the overall direction of flow. Heating or cooling fluid may be passed around the tubes 13, 14. Complementary feed pipes and paddles may be provided for each shape. If the liquid contains pure solid particles e.g. of catalyst, which had to settle, funnel shaped down pipes are provided. |
