Abstract: Fluidised eddy material (2) is placed in an eddy bed drier (1) and contains material in a wet state for drying. Eddy gas (3) is heated via a heat exchanger, and distributed via a distributor floor (1a) into the drier. Through a filter (1b), eddy gas (5) and solvent vapour leave the drier. Entry of the product to be dried into the eddy bed drier, and withdrawal of the dried product occur via pipe conduits and known conveyor components (6,7). The eddy bed drier is arranged in an installation (8) for prodn. of a high frequency field by which the wet product is dried by dielectric heat. USE - To dry temp.-sensitive wet material.

Abstract: Prodn. of oxidised polyethylene (I) with acid number of 10-40 is carried out by oxidising finely-divided HDPE below its softening point and above 100 deg.C with air and/or O2, using HDPE contg. 0.015-0.5wt.% free radical organic cpd. (II). Oxidn. is carried out with oxidn. gas contg. 30-600 mg O3/kg HDPE-h. Pref., the oxidn. gas contains 80-300 mg O3. High temp. oxidn. is followed by vacuum treatment.
