Abstract
The invention concerns a collector assembly () for a gaseous fluid suitable for being disposed in a reaction section with a moving bed of catalyst of a radial reactor. The collector assembly comprises a vertical cylindrical screen (), permeable to gas and impermeable to particles of catalyst, and a vertical cylindrical tube () which is supported by this screen () and disposed in a concentric manner with respect to the screen. The tube () comprises one or more zones () which are permeable to gaseous fluid, comprising a plurality of through holes and a plurality of zones () with a reduced permeability to gaseous fluid compared with the permeable zone. Each zone with a reduced permeability has a porosity, defined as the ratio between total permeable surface area of the zone and total developed surface area of this zone, in the range 0 to 0.005.
