Description

A simple process for the concentration of aqueous nitric acid has been demonstrated in pilot plant operation as part of the Consolidated Fuel Reprocessing Program at the Oak Ridge National Laboratory. A mathematical model of this process shows reasonable agreement with important experimental data. This extractive distillation process utilizes an aqueous solution of magnesium nitrate as the solvent and is a simplified version of that used commercially. The process features two vessels for the distillation and solvent recovery operations. The acid feed and product compositions and flow rates were determined with reasonable certainty
