ABSTRACT:
A process for the production of potassium bicarbonate, involving the dry carbonation of potassium carbonate with a carbon dioxide gas stream having temperatures of up to 115.degree. C. and relative humidities of from 40% to 75%. High conversions of the potassium carbonate, carbon dioxide and water vapor reactants are achieved, with the formation of a substantially dry bicarbonate product which may be further processed without additional drying or handling expense.
