P-23 Development technique to isolate potassium from molasses

Abstract

A new method of isolating potassium from molasses that has not been used for value-added use because of high potassium concentration was studied. Molasses was diluted with certain rate of water, and sulfuric acid and calcium salts were added to this diluent. Only by this way, it was found possible to separate the molasses into liquid fraction containing a high amount of carbon sources and solid fraction including potassium salts (CaK_2(SO_4)_2 nH_2O). Thus, it was made possible to use the molasses for value-added use, i. e., the liquid fraction was used as valuable carbon sources, and the solid fraction as special fertilizer including potassium richly.
