NaOH (Caustic soda) may be produced in a process from the following reactions: CaCO3 = CaO + CO2 CaO+H2O = Ca(OH)2 2NaCl + CaCO3 = Na2CO3 + CaCl2 Na2CO3+ Ca(OH)2 = 2 NaOH + CaCO3 1. Write the overall reaction for NaOH production using salt (NaCl), limestone (CaCO3) and water (H2O) as raw materials 2. What are the required feed rates of salt (NaCl), limestone (CaCO3) and water (H2O) required to produce 1000 lbm/day of NaOH as a 10% wt solution.
