<p>PROBLEM TO BE SOLVED: To provide a desalting agent containing an auxiliary agent adequate for lessening the hygroscopicity of desalting residues up to a high range of a chlorine concentration. SOLUTION: Finding is made that the flux fired goods among diatomaceous earths have the water holding property higher than that of other diatomaceous earths, retain the performance as the powder and granular materials of the desalting residues in spite of the high moisture content in the desalting residues and are excellent in the effect of suppressing deliquescence. More preferably, if the deliquescence of the calcium-base desalting agent is attempted to be lessened by using the fired goods of the conventional diatomaceous earths as the auxiliary agents when the chlorine concentration of the desalting residues is high, there is a need for incorporating a large amount of the auxiliary agents therein, the cost for the agents increases and the amount of landfill in the case of disposal of the desalting residues for final landfill increases and therefore such is undesirable but according to this desalting agent, the equal or better effect can be obtained with the smaller amount.</p> |
