  • Patent number: 9446369
    Abstract: Apparatuses and processes are provided for stripping gaseous hydrocarbons from particulate material. One process comprises the step of contacting particles containing hydrocarbons with a stripping vapor in countercurrent flow to remove at least a portion of the hydrocarbons with the stripping vapor to form stripped particles. Contacting the particles includes advancing the particles down a sloping element of a structured packing toward a reinforcing rod that is disposed along a lower channel portion of the sloping element. The particles are advanced over the reinforcing rod. The particles are contacted with the stripping vapor that is rising up adjacent to the lower channel portion.
    Type: Grant

  • Patent number: 7332132
    Abstract: An apparatus and process for stripping gases from solids comprises a structured packing in a stripping section of a vessel. The structured packing comprises a plurality of corrugated ribbons with each corrugated ribbon having at least two faces angular to each other. The ribbons at least partially obstruct passage of the solid particles. Edges of adjacent ribbons defining openings for the passage of contacted particles.
