Abstract

técnica de retirada contínua e controle de pressão de reatores de polimerização. são descritos técnicas e sistemas para produção de uma poliolefina utilizando reatores em série. modalidade descritas incluem técnicas e sistemas para polimerizar um monômero em um primeiro reator de polimerização para formar uma primeira poliolefina,descarregando uma primeira lama continuamente a partir do primeiro reator de polimerização para um segundo reator de polimerização, e descarregar uma segunda lama continuamente a partir do segundo reator de polimeração. utilizando dispositivos de retirada contínua dispostos em qualquer dos ou em ambos os reatores, o controle de pressão pode ser obtido, de modo que a taxa de transferência emtre ambos os reatores e a retirada a partir dos mesmos estejam dentro de uma variação desejada.
