ABSTRACT:
Apparatus for the treatment of a liquid hydrocarbon charge containing solids or solids-forming contaminants, e.g., inorganic solids, metals and asphaltenes, which includes a contactor vessel having a liquid charge inlet, a vaporizing media inlet above the charge inlet and a vapor-solids outlet. An atomizer is positioned in the charge inlet for forming small particles of the liquid charge and directing the particles of liquid in a substantially horizontal flat pattern into the contactor vessel. A premix downcomer having a dispersion grid positioned therein is located in the vaporizing media inlet for introducing a fluidized mixture of a gas dispersion media and hot circulating solid particles into the contactor vessel in a substantially vertical flat pattern to traverse the path of the liquid particles and intimately contact the liquid particles. The vapor-solids-outlet is positioned in the contactor vessel substantially opposite the liquid charge inlet to receive product vapors and entrain solid particles and rapidly pass the same into cyclones connected to the vapor-solids-outlet for separating solid particles from product vapors. A stripper vessel is located beneath the contactor vessel for receiving heavy solid particles and stripping hydrocarbons therefrom.
