Abstract: The invention relates to a lining (10) intended to be positioned inside a chamber (1) to promote contact between fluids circulating inside said chamber, said lining comprising a plurality of separate criss-crossing strips (12): —first strips (12.1i) parallel to a first direction (D1) and defining a plurality of first planes spaced apart from each other, —second strips (12.2i) parallel to a second direction (D2) forming an angle with the first direction (D1) and defining a plurality of second planes spaced apart from each other. In each first plane, a free space separates two first adjacent strips I a direction perpendicular to the first direction and receives a second strip, the first and second strips being secured together. Each separate strip of at least one stage is perforated (12) and selected from a strip made from a stamped metal sheet and a strip made from an expanded metal sheet.

Abstract: Process for separating gases from a fluidized gas/solid mixture, comprising at least one injection of gas and optionally at least one injection of solids into and at least one discharge of solids from said fluidized bed, a discharge for gas from the mixture characterized in that it comprises a step of separating the solids entrained by the gas by means of an internal placed in that portion of the fluidized mixture where the voidage is greater than 0.7, occupying less than 10% of the free cross section of the bed.
