Abstract

"PROCESSO PARA O CONTROLE DE INCRUSTAçãO EM FOLHA EM REATORES DE FASE GASOSA". A presente invenção refere-se à medida e ao controle da estática em um reator de polimerização em fase gasosa. Em particular, as modalidades referem-se à monitoração de estática de transporte em uma zona de embarque durante a polimerização em fase gasosa para determinar o início dos eventos de descontinuidade do reator tais como incrustação em blocos e em lâmina. As modalidades também referem-se à monitoração de estática de transporte para determinar a necessidade de adições eficazes de aditivos de continuidade que minimizam a atividade estática do reator e evitando assim os eventos de descontinuidade.
