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.
