Abstract

"PROCESSO PARA TRATAR UMA POLIOLEFINA DESCARREGADA DE UM REATOR DE POLIMERIZAçãO DE OLEFINA". Processo para tratar poliolefina descarregada de um reator de polimerização de olefina o qual compreende as etapas de descarregar de um reator de polimerização uma suspensão que compreende poliolefina e diluente; submeter dita suspensão a uma descompressão tal que o diluente é evaporado e uma mistura de gás/poliolefina é formada; descarregar dita mistura de gás/poliolefina em um vaso de coleta; controlar um nível de poliolefina depositada no vaso de coleta; descontinuamente transferir a mistura de poliolefina/gás no vaso de coleta em um vaso de concentração; descarregar dito vaso de concentração em tal um meio que dita mistura de poliolefina/gás é transferida no depósito de purga de hidrocarboneto. Modalidades também compreendem o uso de dois vasos de concentração interconectados e a recuperação otimizada do diluente do depósito de purga.
