Abstract

Patente de Invenção: <B>"PROCESSO PARA O TRATAMENTO DE FLUXOS DE GáS DA FABRICAçãO DE POLIOLEFINA"<D>. A invenção diz respeito a um processo para o tratamento de uma corrente de gás obtida da p rodução de poliolefinas e contendo compostos não reagidos. De acordo com o processo, os compostos não reagidos são removidos da corrente de gás e, quando assim desejado, estes compostos são direcionados para outro tratamento. De acordo com a invenção, os compostos não reagidos são separados da corrente de gás por separação de membrana. Assim a separação de gases é facilitada, uma vez que mediante o acoplamento do sistema de membrana em conjunto com as colunas de destilação, a destilação pode ser realizada em uma temperatura de topo substancialmente mais elevada. Mediante o uso do sistema de membrana é possível eficazmente remover os gases mais leves, que devem do contrário acumular no processo.
