Abstract

métodos para operar uma unidade de hidrogenação de acetileno de um sistema integrado para a produção de olefinas e para operar uma unidade de hidrogenação de acetileno de um sistema de craqueamento sob vapor que integra um efluente de desidrogenação catalítica fluidizada de um sistema de desidrogenação catalítica fluidizada. trata-se de um método para operar uma unidade de hidrogenação de acetileno de um sistema de craqueamento sob vapor que integra um efluente de desidrogenação catalítica fluidizada (fcdh) de um sistema de desidrogenação catalítica (fcdh) pode incluir separar um gás craqueado do sistema de craqueamento sob vapor em pelo menos uma alimentação de hidrogenação que compreende pelo menos acetileno, co e hidrogênio, introduzir o efluente fcdh no sistema de separação, combinar o efluente fcdh com o gás craqueado a montante do sistema de separação, ou ambos. o método pode incluir hidrogenar acetileno na alimentação de hidrogenação. a concentração elevada de co na alimentação de hidrogenação devida ao efluente fcdh pode reduzir uma taxa de reação de hidrogenação de acetileno. a unidade de hidrogenação de acetileno pode operar a uma temperatura elevada em relação às temperaturas normais de operação quando a porção do efluente fcdh não está integrada, de modo que uma concentração de acetileno no efluente hidrogenado seja inferior a uma concentração limite de acetileno.
