Abstract
The invention relates to a process for fractioning vinasse, in which process the pH value of the vinasse is lowered by adding acid, and the formed precipitate is separated in order to obtain an inorganic fraction, whereupon an organic fraction remains. The invention also relates to the products obtained. The inorganic fraction mainly contains potassium salt, and it is useful for example as a fertilizer. The organic fraction mainly contains organic acids, and it is useful for example as an additive in animal feed and in producing silage.
