Abstract

"PROCESSO PARA FABRICAR UMA MONONITRILA INSATURADA", selecionada do grupo consistindo de acrilonitrila e metacrilonitrila compreendendo reagir uma olefina selecionada do grupo consistindo de propileno e isobutileno, amónia e oxigênio em uma zona de reator na presença de um catalisador para produzir um efluente de reator contendo a mononitrila insaturada correspondente, transferir o efluente de reator contendo a mononitrila insaturada para uma coluna de resfriamento em que o efluente de reator contendo a mononitrila insaturada é contatado com pelo menos um primeiro fluxo aquoso para resfriar o efluente de reator, transferir o efluente de reator resfriado contendo a mononitrila insaturada para uma coluna de absorção em que o efluente de reator contendo mononitrila insaturada é contactado com pelo menos um segundo fluxo aquoso para separar e remover a mononitrila insaturada como um fluxo de fundo da coluna de absorção, transferir o fluxo de fundo contendo a mononitrila insaturada para uma seção de recuperação e purificação onde a mononitrila insaturada é recuperada e purificada e reciclar pelo menos um fluxo de processo aquoso para melhorar a eficiência do processo em que a melhoria compreende tratar pelo menos um fluxo aquoso antes de reciclar no fluxo de processo para reduzir pH reduzindo dessa maneira a quantidade de impurezas mínimas presente no fluxo de reciclagem aquoso.
