ABSTRACT:
A process is provided for the preparation of valuable products from vinasse which contains potassium salts. The process comprises concentrating the vinasse to a dry matter content of 50-80% dry solids and separating the formed crystals in a concentration step to form a supernatant which is free of potassium salts. Ammonium sulphate is added to the vinasse before or during concentrating the vinasse.
Furthermore, clarification of the supernatant is carried out to provide for the separation of betaine, PCA, succinic acid or citric acid. Filtration, or microfiltration is used for the clarification and a chromatographic separation is used for the separation of betaine as well as the other products. Potassium salts are obtained from the crystals to provide for a fertilizer.
