Abstract

1,269,474. Separation of volatile solvents from polymers. SOLVAY & CIE. 4 Nov., 1969 [7 Nov., 1968], No. 54016/69. Heading BIB. [Also in Division C3] Hydrocarbon solvent and monomers are separated from admixture with an olefine (CO) polymer by introducing the mixture through pipe 4 into tower 5 wherein the mixture undergoes a reduction in pressure and is contacted with an aqueous suspension of (CO) polymer supplied through pipe 6 so that the solvent and monomers are vaporized, and leave the top of the column. The aqueous suspension of (CO) polymer is withdrawn from the base of the column and is pumped through a heat-' exchanger; some of the suspension is then returned to the top of tower 5 through pipe 6, and the remainder is passed to a filter. Steam may be introduced into the tower, if necessary. The tower contains cone-shaped baffles. (For Figure see next column)
