Abstract

PURPOSE: To remove Ca and Mg as settleable flocks by adding lime to crude salt water contg. sodium bicarbonate, NaCl, Ca and Mg to maintain the pH of the salt water in a specific range in two steps.
CONSTITUTION: The molar ratio of NaHCO3/Mg in crude salt water is regulated to 5W40, esp. 7W20, and lime such as quick lime or slaked lime is added to the water to maintain the pH of the water at 8.5W10.5 for above 5 min pref. with moderate stirring. The pH-regulated crude salt water is then shifted to other reactor, and lime is added under the same condition to maintain the pH at 11.0W12.5, forming flocks. The flocks-contg. water is allowed to overflow into a flock formation vessel, and the flocks contg. Mg and Ca settled in the vessel are separated and removed to obtain purified salt water.
