Abstract
Packing for a column for treating solid particles by direct contact between an ascending gas current and solid particles flowing countercurrent by gravity within the packing. The packing has an ordered structure, consisting of superposition of at least two stacking elements (1,12), each comprising shaped elements (2, 9) arranged parallel between themselves and with regular spacing, said spacing providing a passage opening between two neighboring shapes between 3 and 20 times, preferably 7 and 15 times, the average granulometry of said particles, and the vertical projection of the shaped elements completely covering a horizontal section of the column. This packing is very specially recommended in the presence of particles with a granulometry greater than 2 mm or having mediocre flow characteristics.
