Abstract

Patente de Invenção: "SISTEMA DE ANáLISE RAMAN PARA CONTROLE DE POLIMERIZAçãO DE OLEFINA". é fornecido um processo de polimerização de olefina em um reator, tal como um reator em loop de polimerização em pasta fluida de olefina. O processo inclui realizar in situ, análise espectroscópica em tempo real de um ou mais constituintes do reator. Os constituintes do reator analisados podem estar presentes no reator tanto na fase líquida como na fase sólida, ou em ambas. Em resposta aos valores medidos in situ, um ou mais constituintes do reator pode (m) ser dosado (s) para o interior do reator.
