Abstract
"PROCESSO PARA PREPARAçãO DE BUTADIENO A PARTIR DE n-BUTANO". A invenção refere-se a um método para produção de butadieno a partir de n-butano incluindo as etapas de A) fornecer uma corrente de gás de entrada a contendo n-butano; B) alimentar a referida corrente de gás de entrada a contendo n-butano a pelo menos uma primeira zona de desidrogenação e desidrogenar o n-butano de uma maneira catalítica não oxidativa, com a obtenção de um fluxo de gás produto b contendo n-butano, 1-buteno, 2-buteno, butadieno, hidrogênio, componentes secundários com baixo ponto de ebulição e opcionalmente vapor; C) alimentar a corrente de gás produto b resultante do processo de desidrogenação catalítica não oxidativa e um gás contendo oxigênio em pelo menos uma segunda zona de desidrogenação e desidrogenar oxidativamente 1-buteno e 2-buteno, sendo obtido um fluxo de gás produto e contendo n-butano, 2-buteno, butadieno, hidrogênio, componentes secundários de baixo ponto de ebulição e vapor, o referido fluxo de segundo gás produto c tendo um teor mais alto de butadieno do que o fluxo de gás produto b; D) eliminar hidrogênio, os componentes secundários de baixo ponto de ebulição, e vapor, sendo obtido um fluxo de gás produto C~ 4~ d, contendo essencialmente n-butano, 2-buteno e butadieno; E) separar o fluxo de gás produto C4 d em um fluxo de recirculação e1 contendo essencialmente n-butano e 2-buteno e um fluxo e2 contendo substancialmente butadieno, por meio de destilação extrativa, e redirecionar o fluxo e1 para a primeira zona de desidrogenação.
