Abstract

processo para a preparação de um polímero multimodal de poliolefina com a remoção de hidrogênio melhorada. a presente invenção refere-se a processo para a preparação de um polímero multimodal de poliolefina em temperaturas a partir de 40 até 150ºc e pressões a partir de 0,1 até 20mpa na presença de um catalisador de polimerização em um primeiro e um segundo reatores de polimerização conectados em série, em que outros reatores de polimerização podem ser conectados aos referidos reatores a montante ou a jusante dos referidos reatores, em que no primeiro reator de polimerização um primeiro polímerio de poliolefina é preparado em suspensão na presença de hidrogênio e no segundo reator de polimerização um segundo polímero de poliolefina é preparado na presença de uma concentração de hidrogênio mais baixa do que no primeiro reator de polimerização, compreendendo: a) retirar a partir do primeiro reator de polimerização uma suspensão de partículas sólidas de poliolefina em um meio de suspensão que compreende hidrogênio; b) alimentar a suspensão a um tambor de cintilação de uma pressão mais baixa do que aquela do primeiro reator de polimerização; c) vaporizar uma parte do meio de supensão; d) retirar uma suspensão esgotada de hidrogênio a partir do tambor de cintilação e alimentar a mesma para o segundo reator de cintilação; e) retirar o gás da fase de gás do tambor de cintilação e alimentar o mesmo para um trocador de calor; f) condensar uma parte do gás retirado do tambor de cintilação ; e g) retornar o líquido obtido no trocador de calor para o processo de polimerização em um ponto no qual a suspensão estiver presente, e um aparelho para a preparação de um polímero multimodal de poliolefina de acordo com o processo.
