Abstract

"PROCESSO E APARELHO PARA A PRODUçãO DE POLìMEROS DE OLEFINA". A presente invenção trata de um processo e de um aparelho para a polimerização contínua de monómeros de olefina em uma cascata de reatores de polimerização. De acordo com o processo, um monómero de olefina é polimerizado primeiramente em uma fase de massa fluida em um diluente de hidrocarboneto inerte em pelo menos um reator de alça e, em seguida, em uma fase gasosa em pelo menos um reator de fase gasosa. De acordo com a presente invenção, uma massa fluida de polímero é continuamente retirada do reator de alça e opcionalmente concentrada. A massa fluida concentrada é conduzida para uma unidade de separador de óleo e gás de alta pressão a fim de remover a fase fluida restante, e alimentada para o reator de fase gasosa. Com o processo descrito na presente invenção, é possível se produzir um polietileno bimodal com boas propriedades. A operação do processo é estável em função desta operação de fato contínua.
