APPARATUSES FOR STRIPPING GASEOUS HYDROCARBONS FROM PARTICULATE MATERIAL AND PROCESSES FOR THE SAME

摘要

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.

主权项

1. An apparatus for stripping gaseous hydrocarbons from particulate material, the apparatus comprising:
a structured packing configured for passage of a stripping vapor and particles that contain hydrocarbons in countercurrent contacting flow to remove at least a portion of the hydrocarbons with the stripping vapor to form stripped particles, the structured packing comprising: a first formed strip comprising a sloping element that has a lower channel portion and an inclined sheet portion that extends generally upward from the lower channel portion; and a reinforcing rod disposed along the lower channel portion.
