Sodium Silicate Plant - Marsina Engineering srl

Caustic soda fed to the reactors undergoes a dissociation generating sodium oxide which, in its turn, reacts with silica contained in the sand so producing sodium silicate. The reaction process, occurring in presence of 12 bar pressure saturated steam, is carried out batch-wise inside stirred reactors, autoclaves type, where silica sand, caustic soda solution at 50% and water are charged in appropriate quantities.
