By increasing the lime dosage, either the trona or soda ash can be converted to caustic soda, a higher-value product. In this process, lime is first slaked and converted to calcium hydroxide (Ca(OH) 2). Next, the lime slurry is combined with soda ash (Ca(OH) 2) + Na 2 CO 3). This yields caustic soda and limestone (2NaOH + CaCO 3). The limestone ...
