The invention relates to a method for separating betaine from fermentation process solutions, vinasse and other sugar beet based solutions on a weakly acid cation exchange resin in H+-form in the chromatographic separation process. A sequence of machine instructions performed by a processor is recorded as trace data. The number of simulations and the number of simulations periods is specified on the basis of a specified information correlation value. The layers of the trilaminate inner liner insulate, water proof, and provide a face cloth for the firefighting textile product.
