<p>PCT No. PCT/FI95/00224 Sec. 371 Date Oct. 18, 1996 Sec. 102(e) Date Oct. 18, 1996 PCT Filed Apr. 19, 1995 PCT Pub. No. WO95/29002 PCT Pub. Date Nov. 2, 1995The 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.</p> |
