Brief description of the contact of the phases, with the placing in suspension and by natural circulation of at least one solid product in the divided state in a fluid, and apparatus for use
P the invention relates to a method of contacting stages in which one or several phases, each constituted by a product which is secured to the divided state are placed in suspension and by natural circulation in a phase constituted by a fluid. / p & & p & the method consists in using a chamber provided at its base with a distributor 7 and containing the cells of the circulation 5a, 5b, 5c, each formed by a duct of the section s which has at its base a baffle defining a free section s such as, 0,12 = s / s & = 0, 60, to supply each cell in the divided substance and to supply each cell with fluid via its free section s, so that the speed v that - at the level of the section s is greater than the minimum fluidization speed of the divided substance. / p & & p & the method applies to one or more of the divided substance in the form of large particles and makes it possible to put them in a turbulent flow in the cells in order to ensure the transfer of material, of heat or in the amount of movement. / p
