Abstract

resumo alívio de pressão para reatores de polimerização de poliolefina múltiplos um sistema de fabricação de poliolefina e método incluindo polimerizar olefina em um primeiro reator para formar uma poliolefina, transferir a poliolefina para um segundo reator, polimerizar olefina no segundo reator, e descarregar uma poliolefina de produto do segundo reator. o sistema e método incluindo operar o primeiro reator com um primeiro sistema de alívio de pressão de reator e o segundo reator com um segundo sistema de alívio de pressão de reator, ambos os sistemas de alívio de pressão para descarga para um sistema de queima, e em que um sistema instrumentado de alívio (ris) é configurado para direcionar pelo menos um intertravamento de processo que diminui um cenário de reação em excesso como um cenário de alívio de sobrepressão.
