Abstract: The invention relates to an injection device (10) configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body (12) of longitudinal direction (X). An internal wall (13) defines a first zone referred to as a contact zone (Z1) and a second zone (Z2). The body has: at least a first and a second inlet opening (14; 16) opening into the said first zone (Z1), so as to respectively inject a liquid and an atomizing gas, at least one outlet orifice (18) situated downstream of the first and second zones, for removing the atomized liquid from the body. The internal wall (13) of the body is provided, between the zones (Z1) (Z2), with at least one chicane (20i) configured so that, in each plane perpendicular to the longitudinal direction of the body containing the said chicane, this chicane extends over just part of the periphery of the internal wall (13).

Abstract: The invention relates to an enclosure (10) of a fluid catalytic cracking unit in which an inner space is defined by a side wall (12) having a longitudinal axis extending substantially in the direction of gravity, said enclosure being provided with a plurality of mechanical separation cyclones (14, 16) located inside the inner space. The enclosure (10) comprises a supporting device (20) attached only to the cyclones (14, 16) by: an annular peripheral support element (202) extending along the side wall (12) in a plane perpendicular to the longitudinal axis (X), separated from the side wall by a predetermined clearance; and a plurality of beams (206, 208) extending in the same plane as the peripheral support element (202), the beams being rigidly connected to the peripheral support element and to at least one mechanical separation cyclone by one end or by an attachment part distant from the ends thereof.
