Fluid treatment facility which operates under pressure and implements a fluidised bed of adsorbent media particles

Abstract

The invention relates to a facility for the treatment of a fluid, comprising a reactor (1) that accommodates a bed of adsorbent media particles, means (2) for injecting and distributing fluid to be treated, which means are in the bottom part of said reactor (1) and are intended to form an ascending flow of fluid within said reactor (1) and allow said bed of adsorbent media particles to be fluidised and expanded, and means (3) for recovering the fluid that has passed within said bed of adsorbent media particles fluidised in this way, characterised in that said reactor (1) is a closed reactor that forms an enclosure making it possible to implement said treatment under pressure, said enclosure having a bottom (11) that accommodates said means (2) for injecting and distributing the fluid to be treated, a substantially cylindrical central body (12) forming a fluidisation column, a substantially cylindrical peripheral body (14) defining an annular chamber (15) around said substantially cylindrical central body (12) delimiting a fluidisation column, said annular chamber (15) accommodating at least one layer of a granular or pulverulent material, a curved cover (13) forming a baffle making it possible to transform said ascending flow into a homogeneous descending flow and to direct said descending flow towards said recovery means (3) via said annular chamber (15).
