METHOD OF CONTINUOUS SOLUTION COPOLYMERIZATION AND REACTOR-DISTRIBUTOR FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

Abstract RU 2144843 C1

FIELD: methods and devices for continuous solution copolymerization. SUBSTANCE: method includes preparation of solution of gas-liquid mixture containing monomers, hydrocarbon solvent and hydrogen; dissolving of catalytic complex components in hydrocarbon solvent; supply of solution of gas-liquid mixture to lower part of corresponding polymerization reactor provided with mixer; supply of solutions of catalytic complex components to polymerization reactor; copolymerization with mixing of reaction mass at high pressure and temperature. Method is distinguished by the fact that preparation of gas-liquid mixture is carried out by stages by preliminary turbulent mixing in successively arranged tubular turbulent nozzles and distribution of gas-liquid mixture in tubular turbulent reactor-distributor among parallel transfer pipelines into separate flows with subsequent maintenance of their turbulent motion in nozzles of diffuser-confuser type before supply to polymerization reactors with parallel connection to reactor-distributor. Reactor-distributor for embodiment of the method is also described. EFFECT: higher efficiency. 3 cl, 2 dwg, 1 tbl, 4 ex
