  • Publication number: 20200109334
    Abstract: The present invention describes a packing with a three-dimensional structure which is particularly suited to creating homogenous and anisotropic mixing between a gas phase and a dispersed solid phase moving in counter-current flow. Application of this packing to the stripper of fluidized catalytic cracking units.

  • Publication number: 20190184331
    Abstract: A tray (100) for a gas/liquid contact column, comprising a plurality of chimneys (108) jutting over a portion (101) of the upper face of the tray for the exclusive passage of gas through the tray; they are substantially parallelepipedal and mutually parallel. At least one of the chimneys (108) is surmounted by an elevated hat (108?) with a streamlined profile which prevents the passage of liquid through the chimney. The hat comprises a lower body (180) which is substantially semi-cylindrical, elongated along the longitudinal axis Y and open towards the top, extended laterally by two planar fins (181, 182) inclined towards the axis of revolution (R) of the lower body at an angle ? in the range 0° to 30° with respect to the axis Z passing through the chimneys, aligned with their height.

  • Publication number: 20190168131
    Abstract: The invention relates to a gas-distributing tray (20) for a column for exchange of heat and/or of material between a gas and a liquid, comprising several protruding chimneys (80) which are substantially parallelepipedal and parallel to one another over a portion (21) of the upper face of the tray for the exclusive passage of the gas (g) through the tray and a zone for collecting the liquid (90) comprising two diametrically opposite weirs (91, 92) for collecting the said liquid (l) on the said tray. The chimneys each comprise an element for distribution of the gas (82) partially overlapping the zone for collecting the said liquid. The invention also relates to an exchange column comprising such a distributing tray and to the use of such a column.
