Abstract

"PROJETOS DE FINALIZAçãO PARA AUMENTAR O CONTEúDO DE POLìMERO EM UM PROCESSO DE POLIMERIZAçãO EM SOLUçãO OLEFìNICA". A capacidade de recuperação de polímeros de unidades de polimerização em solução é aumentada fazendo flasheamento uma solução polimérica que sai de reatores de polimerização olefínica para produzir uma solução polimérica concentrada tendo temperatura reduzida e conteúdo de sólidos entre 10% e 40% em peso. O flasheamento da solução polimérica preferivelmente ocorre em temperaturas pelo menos 20°C maiores que a temperatura de cristalização da solução polimérica concentrada. A solução polimérica concentrada pode ser preparada adiabaticamente e pode ser subseq³entemente finalizada em unidades convencionais de recuperação sem aumentar o risco de formação de gel.
