Abstract
Process and apparatus for stripping fluidized solid particles countercurrently with a stripping fluid. This apparatus comprises at least one packing structure consisting of at least one element the flow cross-section of which is essentially transverse to the chamber axis, said element extending over the entire cross-section of the chamber in the circulation zone and consisting of cells or pathways through which pass the particles and the stripping fluid, said cells or pathways orienting the circulation of the fluid and of the particles to be stripped in approximately radial fashion.
