The application of trash to treasure of the brine pretreatment waste of soda ash plant. A possible application of the waste for acidic gas absorption was investigated. Alkali-metal-based hydroxides can be used to assist in seawater decalcification by CO2. Permit the use of moderate temperature and pressure conditions for mineral carbonation of CO2.
