Abstract

"PROCESSO PARA A PRODUçãO DE ALQUILBENZENO COM EXTRAçãO DE ETANO". Um processo para a produção de alquilbenzeno inclui introduzir benzeno e um alimento de olefina dentro de uma primeira zona de reação de alquilação na presença de um primeiro catalisador de alquilação sob as primeiras condições de reação de alquilação para produzir um primeiro efluente de alquilação contendo alquilbenzeno e uma primeira corrente suspensa de alquilação. A primeira corrente suspensa de alquilação é separada dentro de uma porção de líquida contendo benzeno e uma porção de vapor contendo etano e olefina não convertidos. Uma porção maior da olefina não convertida na porção de vapor da primeira corrente suspensa de alquilação é absorvida dentro de uma corrente de óleo de aromática desetanizado contendo benzeno e alquilbenzeno em uma zona de absorção para produzir uma corrente de óleo rico contendo olefinas e pelo menos um pouco de etano. A corrente de óleo rico é enviada para uma segunda zona de reação de alquilação contendo um segundo catalisador de alquilação sob as segundas condições de reação alquilação para produzir uma primeira corrente de óleo de pobre aromático, que é fracionada em um desetanizador para produzir um vapor de desetanizador suspenso contendo uma porção maior de etano e, uma base líquida de óleo de pobre aromático desetanizado.
