Abstract

processo para a produção de furfural. trata-se de um processo para a produção de furfural a partir de uma composição bifásica incluindo furfural, um solvente orgânico e detritos orgânicos solúveis. o dito processo inclui submeter a composição bifásica a uma etapa de separação de líquido-líquido para fornecer uma fase orgânica e uma fase aquosa. a fase orgânica inclui o solvente orgânico, uma primeira porção do furfural e uma primeira porção de detritos orgânicos solúveis. a fase aquosa inclui uma porção restante do furfural e uma porção restante de detritos orgânicos solúveis. a fase orgânica é submetida a uma etapa de destilação para fornecer uma corrente de furfural e uma corrente de solvente orgânico incluindo o solvente orgânico e a primeira porção dos detritos orgânicos solúveis. a corrente de solvente orgânico é transportada para uma unidade de adsorção para adsorver uma segunda porção dos detritos orgânicos solúveis, formando uma corrente de reciclagem esgotada de detritos orgânicos.
