Study on the Preparing Refined Bittern Experiment by One-Step Method

Use of one -step method shows that it can increase utilization rate of effective CaO in the lime compared with neutralizing method, economize on lime 27.78%, reduce caustic mud 27.78%, and utilization rate of crude bitterns increased by 2.77%. This method makes the crystalline grains of heavy sodium carbonate enlarge, white degree rise, quality improve.
