Abstract: The invention relates to a method for the fractionation of molasses using a chromatographic simulated moving bed system with two or more loops in which the liquid flow can be effected in a system comprising at least two chromatographic partial packing material beds. In the method of the invention, product(s) are recovered during a process comprising one or more of the following phases: a feeding phase of molasses, an eluting phase and a recycling phase. The liquid present in the partial packing material beds with their dry solids profile can be recycled in the recycling phase in one or more loops comprising one or more partial packing material beds.

Abstract: A method for separating sucrose and a second dissolved component from a sucrose-containing solution, preferably a beet-derived sucrose-containing solution, wherein the solution is subjected to a first fractionation by a continuous or sequential chromatographic simulated moving bed process to yield a sucrose-enriched fraction and a fraction enriched with the second dissolved component. The resulting fraction enriched with the second component is subjected to a second chromatographic fractionation that is a simulated moving bed or batch type process, to yield a second sucrose-enriched fraction and a second fraction enriched with the second dissolved component wherein both fractions have an improved yield or purity.

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.

Abstract: The invention relates to a process for decolorization of solutions of sugars, sugar alcohols and betaine. In accordance with the process, a polyaluminium chloride is added to a solution of sugar, sugar alcohol or betaine having a dry substance content of 10 to 70% by weight and a temperature of 60 to 105.degree. C. in a suitable amount so as to obtain a mixture having a pH of 5.5 to 9.5, thereby precipitating the coloured substances, and the formed precipitate is separated from the solution. The invention also relates to the use of a polyaluminium chloride for decolorization of solutions of sugars, sugar alcohols and betaine.

Abstract: The invention relates to the use of an organic acids containing fraction obtained from vinasses and molasses for preserving forage, stimulating microbial growth and activity, and enhancing forage utilization. The fraction may be used as such, or mixed with forage, or used together with a microbe that resists the acidity of the fraction and produces acid.

Abstract: The invention relates to a process for preparing vinasse suitable for a column process, in which process dilute vinasse is clarified by means of a high-efficiency centrifuge, after which the vinasse is concentrated and potassium is removed. The invention also relates to the vinasse and the potassium sulphate crystals prepared with the above-described process.

Abstract: The invention relates to a method for fractionating a solution by a chromatographic simulated moving bed method in which the liquid flow is effected in a system comprising at least two sectional beds in different ionic forms. The fractions enriched with different components are recovered during a multi-step sequence including the following operations, i.e., phases: feeding phase, eluting phase, and recycling phase. The liquid present in the sectional packing material beds with its dry solids concentration profile is recycled during the recycling phase in a loop comprising one, two, or more sectional packing material beds. The method can be employed for the following examples, fractionating sulphite cooking liquor, molasses, and vinasse.
