Abstract
1364210 Magnesium chloride and sodium bicarbonate RESEARCH FOUNDATION OF NOVA-SCOTIA 27 Nov 1972 [16 Feb 1972] 54627/72 Heading C1A Magnesium chloride and sodium bicarbonate are produced by (a) reacting an aqueous magnesium hydroxide slurry with carbon dioxide in a first carbonation stage so as to produce an aqueous magnesium carbonate slurry and (b) reacting said mangesium carbonate slurry with carbon dioxide and a concentrated aqueous sodium chloride solution in a second carbonation stage at a temperature below 30‹ C. and at an elevated carbon dioxide pressure (e.g. 25 to 200 p.s.i.) so as to produce a solid phase comprising sodium bicarbonate and a liquid phase comprising magnesium chloride and unreacted sodium chloride. The magnesium hydroxide slurry may be produced in situ by reacting magnesium oxide with water and the sodium bicarbonate produced may be separated, dried and calcined to produce sodium carbonate and the CO2 produced recycled to the second carbonation stage. The liquid phase produced may be evaporated and the sodium chloride and any magnesium carbonate present crystallized therefrom and recycled to the second carbonation stage. The magnesium chloride may then be removed from the remaining solution by evaporation and crystallization and may be dehydrated and utilized in an electrolytic cell for magnesium metal and chlorine production.
