  • Process for reducing calcium ion concentrations in alkaline alkali metal chloride brines
    Patent number: 4277447
    Abstract: A process for reducing calcium ion concentration in alkaline alkali metal chloride brines containing an alkali metal hydroxide is disclosed. The process comprises admixing an alkali metal bicarbonate with the alkaline brines to form an insoluble calcium salt, removing the insoluble calcium salt from the brine, and recovering a purified alkali metal chloride brine having reduced calcium ion concentration.The process produces alkali metal chloride brines suitable for use in electrolytic diaphragm cells while substantially reducing the amount of acid required to neutralize the brines.
