Abstract

1 / 1 resumo “mã‰todo e aparelho para separar tolueno de mãšltiplas correntes de hidrocarboneto” sã£o fornecidos mã©todos e aparelhos para separar tolueno de mãºltiplas correntes de hidrocarboneto. um mã©todo inclui fracionamento uma primeira corrente de hidrocarboneto, que inclui bases de fracionamento depletadas de benzeno do fracionamento de benzeno, em uma primeira zona de fracionamento em uma primeira corrente de topo do fracionamento que inclui tolueno e uma primeira base de fracionamento. uma segunda corrente de hidrocarboneto, que inclui tolueno e ã© substancialmente livre de compostos tendo uma maior pressã£o de vapor que tolueno, ã© fracionada em uma segunda zona de fracionamento em uma segunda corrente de topo do fracionamento incluindo tolueno e uma segunda base de fracionamento. a segunda zona de fracionamento estã¡ no isolamento lã­quido e em comunicaã§ã£o de vapor com a primeira zona de fracionamento. a primeira base de fracionamento ã© removida da primeira zona de fracionamento e da segunda base de fracionamento ã© removida da segunda zona de fracionamento separada da primeira base de fracionamento. a primeiro e segunda correntes de topo do fracionamento sã£o combinadas para produzir uma corrente de topo do fracionamento combinada.
