Abstract
A solute and a solvent with close boiling points or close polarities are separated and concentrated by vaporizing at least one of the solvent and solute, and selectively adsorbing the vaporized component in an apparatus having a vessel, and an absorbent with an opening into the vessel.
Claims26
A method for separating a solute from a solvent and concentrating a solution, comprising the steps of:
- vaporizing at least one of the solvent and the solute;
- selectively adsorbing at least one of the vaporized solvent and the solute on an adsorbent which has an ability to selectively adsorb on of the solvent and the solute;
- thereby selectively separating the solvent and the solute;
- and increasing the concentration of the solute in the solution;
- wherein the boiling points or the polarities of said solute and said solvent are different from each other.
