Document Type and Number:
Japanese Patent JP2018071870
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a drying method of an ion exchange resin capable of suppressing the elimination of an ion exchange group and reducing moisture content at low cost.SOLUTION: A drying method of an ion exchange resin includes: (A) a liquefaction step of liquefying an organic compound (a) being a gas in a condition of 25°C and 1 atm., (B) an extraction step of extruding moisture to the organic compound (a) liquefied from the ion exchange resin by bringing the liquefied organic compound (a) into contact with the ion exchange resin, (C) a gas-liquid separation step of separating the water-containing liquefied organic compound (a) into water and the gasified organic compound (a), and (D) a returning step of returning the separated gasified organic compound (a) to the step (A).SELECTED DRAWING: Figure 1
