Abstract:
A process for the stripping of entrained and/or adsorbed hydrocarbons from particulate material, said process comprising:contacting particles with a hydrocarbon stream; disengaging hydrocarbons from the particles after contact with said hydrocarbon stream to produce a stream of contacted particles containing entrained or adsorbed hydrocarbons passing the contacted particles downwardly through a plurality of sloped stripping baffles; discharging a stripping fluid upwardly through a plurality of openings distributed over the entire sloped surface of each stripping baffle to provide at least one opening for each square foot (0.09 square meter) of the sloped surface of each baffle and stripping hydrocarbons from the particulate material; recovering stripping fluid and stripped hydrocarbons from the stripping baffles; and recovering stripped particles from the stripping baffles.
