Abstract: A degassing column comprising a tubular shell provided with a plurality of apertured plates; the plates are vertically spaced within said shell; a gap uniform in width over the periphery is left between each plate and said shell; each of said plates is penetrated by at least one eccentrically arranged conduit comprising a draining shaft in the upper portion thereof and a feed shaft in the lower portion below the penetrated plate; the apertures in said plates have a diameter of less than 5 mm; and a surface portion of each plate underneath each conduit is impermeable, said impermeable surface portion being one to two times the cross-section of said conduit. More specifically, each plate is supported by a plurality of generally wedgeshaped mountings fastened to the inside of the shell, and by a ring which is level with the said mountings and is fastened to the inside of the shell, the ring being interrupted at least in the regions of the said mountings.

More specifically, each plate is supported by a plurality of generally wedge-shaped mountings fastened to the inside of the shell, and by a ring which is level with the said mountings and is fastened to the inside of the shell, the ring being interrupted at least in the regions of the said mountings. A capping sleeve is slipped over each draining shaft. The capping sleeve comprises an upper portion whose cross-section is similar to that of the draining shaft, and a lower portion of larger cross-section, which lower portion overlaps and is securely connected to the upper portion.
