Optimization of a Solvay-Based Approach for CO2 Capture

Abstract—The present work optimizes the CO2 capture based on the Solvay process, where carbon dioxide is passed into ammoniated brine and reacts with sodium chloride to form a precipitate of sodium bicarbonate and a soluble ammonium chloride. The process has the dual benefit of decreasing sodium concentration in the reject brine and reducing carbon dioxide emissions to the atmosphere. Process parameters were studied in a semi-batch reactor to determine their effect on CO2 capture efficiency and ions removal. The optimum conditions for maximum CO2 capture efficiency and ions removal have been determined using response surface methodology. The optimum CO2 capture efficiency and ions removal was found to be at temperature of about 19 oC, a gas flow rate of 1.54 L/min, and a molar ratio of 3.3NH3:1NaCl. The CO2 capture efficiency in 180 min was equal to 86% and the maximum sodium removal was 33%. These results indicated the technical feasibility of the Solvay approach for the capture of CO2 through reactions with desalination reject brine.

Index Terms—Desalination reject brine, CO2 capture, sodium bicarbonate, sodium removal, Solvay process.
