ABSTRACT:
A reduced pollutant-containing salt mixture and method of making same is provided wherein a salt mixture partially comprised of calcium acetate and partially comprised of at least one other pollutant salt is produced by mixing a pollutant salt-containing solution and a calcium acetate-containing solution and converting said mixture into a solid salt containing both the pollutant salt and the nonpollutant calcium acetate. A process option involves chemically reacting calcium chloride and calcium acetate in a calcium chloride-to-calcium acetate mole ratio in the range from 0 to 1 to produce a non-deliquescent salt. A further process option includes mixing either dry calcium chloride or dry sodium chloride with dry calcium acetate to obtain a reduced pollutant-containing salt mixture.
