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; the first formed strip comprising first alternating segments that define a first vertical element that has a first upper portion and a first lower portion, wherein the first alternating segments each have a first upper sloping element extending from the first upper portion at a first incline to the first vertical element, wherein the first upper sloping elements of adjacent segments of the first alternating segments are angular to each other, wherein the first upper sloping elements each have a first lower channel portion and a first inclined sheet portion that extends generally upward from the first lower channel portion, wherein the reinforcing rod is a first upper reinforcing rod that overlies the first upper portion of the first vertical element and that is disposed along the first lower channel portions, and wherein one of the first upper sloping elements is the sloping element, and one of the first lower channel portions and one of the first incline sheet portions are the lower channel portion and the inclined sheet portion, respectively, the first alternating segments each have a first lower sloping element extending from the first lower portion at a second incline to the first vertical element, wherein the first lower sloping elements of adjacent segments of the first alternating segments are angular to each other; and a reinforcing rod disposed along the lower channel portion. |
