Abstract

"PROCESSO PARA A PRODUçãO CONTROLADA DE POLIETILENO E SEUS COPOLìMEROS". é descrito um processo para a produção controlada de polietileno de alta densidade (PEAD) ou polietileno de baixa densidade linear (PEBDL) em reatores fase gás, isolados ou combinados, usando catalisadores de cromo ou Ziegler Natta, dotado de controle em linha de certas variáveis de processo bem como de propriedades físicas da resina produzida. O processo compreende o uso de modelos para a inferência das propriedades físicas e das variáveis de processo que não são medidas continuamente e modelos relevantes para o controle dessas propriedades e das condições operacionais do processo em estudo. O controle das variáveis de processo proporciona ainda a maximização da taxa de produção e do rendimento do catalisador na reação de polimerização.
