Abstract
Sodium bicarbonate crystals, comparable in size and quality to those normally obtained in the operation of ammonia-soda process, are obtained by carbonating sodium chloride brine, which is free from ammonia, with a stoichiometrically equivalent amount of carbon dioxide at elevated temperature and under pressure in the presence of an amine, which is a base at least as strong as ammonia, having a boiling-point at atmospheric pressure of 100-360 DEG C. and having a formula NR1R2R3 wherein R1, R2 and R3 are hydrogen, alkyl radicals containing from 2-6 C. atoms, alkanol radicals containing from 2-4 C atoms, or primary amino-alkyl radicals containing from 2-4 C atoms and wherein no more than two of R1, R2 and R3 are hydrogen. Amines may be mono-, di-, or tri-ethanolamine, n-amylamine, 2-ethyl butylamine, or ethylene diamine. Brine is charged into a pressure vessel and the amine is added. CO2 or a gas containing CO2, e.g. flue gas, is supplied to apply a CO2 pressure 20-60 p.s.i., preferably 40 p.s.i. The contents of the vessel are agitated, e.g. with a paddle type mixer, during reaction at 65-100 DEG C., preferably 80 DEG C. The product is cooled, the crystals are filtered off, and the amine is recovered for recycling. In an example the molar ratio of amine to NaCl is 1.1 : 1.
