Abstract
Process and apparatus for fluidized bed mixing of fluids and gases in which the fluid is injected with a high angular velocity through a relatively narrow, preferably single, orifice (3). The angular velocity may be imparted by injecting the fluid at high velocity tangentially at the periphery of the squate chamber (4) so that angular momentum is gained as it spirals inwards towards orifice (3). Optionally, an open-topped hopper (5) for solids is suspended above orifice (3). The lower end of the hopper (5) terminates in a second orifice (7) located vertically above orifice (3). The solid particles are thereby swept radially outwards towards the wall of the chamber (1) in co-current admixture with the fluid.
