Abstract

"PROCESSO PARA EPOXIDAçãO DE OLEFINAS". A presente invenção refere-se a um processo para o tratamento de uma corrente de produto da epoxidação de olefinas que contém olefina, óxido de olefina, solvente orgânico miscível em água e água, por separação desta corrente de produto em um produto superior contendo olefina, óxido de olefina e solvente orgânico, e em um produto inferior contendo solvente orgânico e água, em que a separação ocorre em um pré-evaporador com no máximo 5 estágios de separação teóricos, e 20 a 60% da quantidade total de solvente orgânico introduzido com a corrente de produto são removidos com o produto superior e o resíduo fica no produto inferior, bem como a um processo para a epoxidação de olefinas que inclui este estágio de tratamento.
