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 lower section of the sloping element. The particles are passed through a drainage gap formed between a pair of reinforcing rod sections that are disposed adjacent to the lower section of the sloping element. The particles are contacted with the stripping vapor that is rising up adjacent to the drainage gap.
