Abstract
The present invention relates to a method and an arrangement for separation and recovery of at least one carboxylic acid and furfural from a dilute aqueous mixture thereof. In the method of the present invention a dilute aqueous mixture comprising at least one carboxylic acid and furfural is extracted with methyltetrahydrofurane, and at least one carboxylic acid and furfural are recovered. The arrangement of the present invention comprises an extraction unit 302 for carrying out extraction of at least one carboxylic acid and furfural from dilute aqueous mixture with methyltetrahydrofuran, connected to distillation unit 307 for carrying out distillation of the extract 305 from the extraction unit 302, and connected to acids distillation unit 320 for carrying out distillation of the bottom stream 308 from the distillation unit 307 to separate at least one carboxylic acid and furfural.
