Abstract
"PROCESSO E APARELHO PARA PREPARAçãO DE OLEFINAS". A invenção refere-se um processo e a um aparelho para preparação de olefinas, em que uma corrente de alimentação contendo hidrocarbonetos, por exemplo nafta, é convertida em uma planta de tratamento (1), em particular, uma refinaria ou planta de olefinas, em olefinas desejadas, por exemplo, etileno e propileno. Neste processo, pelo menos parte das frações contendo olefinas com cadeias relativamente longas, em particular, olefinas tendo pelo menos quatro átomos de carbono, obtidas na planta de tratamento (1), é transferida para um estágio de conversão de olefinas (12). Neste estágio de conversão de olefinas (12), pelo menos parte das olefinas com cadeias relativamente longas é convertida em olefinas de cadeias mais curtas. Como estágio de conversão de olefinas, é possível usar, por exemplo, um reator catalítico, em particular um reator de leito fixo. Para aumentar a produção das olefinas desejadas é proposto que o estágio de conversão de olefinas (12) seja precedido por um estágio de separação parafina/olefina (23). Neste estágio de separação parafina/olefina (23), a corrente de alimentação é separada em uma corrente de parafina, por exemplo, uma corrente contendo butano e pentano, e uma corrente de olefina, por exemplo, uma corrente contendo buteno e penteno, em particular por destilação extrativa. Enquanto as parafinas obtidas desta maneira são recirculadas para a planta de tratamento (1), por exemplo, para o forno de craqueamento (3) da planta de olefinas, as olefinas são recirculadas para o estágio de conversão de olefinas (12).
