Lime in the Production of Soda Ash | Graymont

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 ...

1980s). Soda ash is very plentiful in the United States and is obtained almost entirely from natural sources of trona ore . However, it is more expensive to mine soda ash than to produce 50 percent caustic, so increased use of soda ash is not likely to occur unless the price of caustic is relatively high (Chenier 1992, DOW 1999).
