Separation of Sodium Chloride and Sodium Sulphate from the Sea Water Eliminated Magnesium and Calcium Salts by means of Sodium Hydroxide and Sodium Carbonate

説明

The separation of the components from the sea water eliminated Mg⁺⁺ and Ca⁺⁺ completely by the treatment with NaOH and Na₂CO₃ was calculated graphically. It was assumed that the vaporization being done at the constant temperature, 110°C, and the refregeration down to the temperature -6°C may be used. Four methods to separate NaCl and Na₂SO₄ were considered by the combinations of evaporation, refregeration and dilution. By using the isothermal equilibrium diagram for the four components system of the reciprocal salts pair Na₂Cl₂+K₂SO₄=Na₂SO₄-K₂Cl₂, as a calculating diagram, it was calculated the quantity and the quality of the salts separated, water evaporated, water to be added and the mother liquor to be remained. The separation of potassium salts was not treated in this paper.
