Abstract

A process for concentration of nitrate acid with the preparation of calcium nitrate comprises distillation of solutions of nonconcentrated nitrate acid with the removal of water vapors and concentrated nitrate acid and diluted acid solution of calcium nitrate, treatment of acid diluted solution of calcium nitrate with lime milk and withdrawal of its part as finished product or supply to granulation, concentration of the second part of solution of calcium nitrate and further return of the obtained concentrated solution of calcium nitrate to distillation. Distillation is carried out in two stages.
