Abstract: The invention relates to an improved process, wherein polyolefins are freed from saturated liquid residual hydrocarbons with the aid of water and steam. The improvement comprises A. introducing the hydrocarbon-containing polyolefin into an aqueous emulsifier-containing solution having a surface tension at 20 DEG C. of about 50 to 60 dynes/cm with respect to air; stirring the resulting mixture and converting it to a homogeneous dispersion, the aqueous dispersion containing about 10 to 40 weight % of the polyolefin; B. introducing the dispersion into the upper portion of a column provided with 5 to 30 sieve plates and overflow weirs and contacting the dispersion in countercurrent fashion with steam of about 100 DEG to 120 DEG C.

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 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.
