Stripping method for extracting solid fluidized particles and implementing device

The present invention relates to the processing of solid particles in fluidized beds. Its object is more specifically a method and a device to process solid particles in a fluidized bed by a fluid circulating against their flow direction, in particular in order to eliminate the components carried along with these particles and/or absorbed on them. This processing is commonly designated by the term "stripping". The invention concerns a stripping method for extracting solid fluidized particles whereby the particles to be stripped are subjected to a first stripping in a first chamber (), then at least a second stripping in a second chamber () wherein are provided solid/gas separating means allowing the gaseous fluids derived from the second stripping to directly pass through from the bottom to the top but preventing them from going up again into the first chamber (). The invention also concerns a device for implementing said method.
