Abstract
A process is disclosed for converting dilute brines of sodium carbonate and sodium bicarbonate to form feed solutions from which sodium based chemicals may be recovered. The sodium bicarbonate in a dilute brine is neutralized and the brine then fortified with calcined trona to form a feed liquor concentrated in sodium carbonate from which sodium based chemicals may be recovered in a Monohydrate or other crystallization process.
