Abstract
A fluid distributing-collecting process using a device for bringing fluids and solids into contact comprises several distributor plates and several panels for mixing, distributing or extracting fluids. The system for practicing the method includes at least one level one chamber in connection with the outside of said device with at least one hose and, at least one level two chamber that is linked with the level one chamber and that comprises one or more connecting hoses of a selected length that are arranged in at least one zone. The zone is identified relative to an angle &agr; relative to a radius of a plate and corresponds to a given angle sector, whereby hose lengths, angle &agr; and the angle sector are selected in accordance with the process so that injected fluid arrives approximately at the same time on all of the panels of the same plate. This process is used for separation of paraxylene in a simulated moving bed.
