How many tons of salt are needed to produce one ton of caustic soda? (100%)
Those who have studied the principles of chemical engineering know how to carry out the calculations. The values obtained through reaction equations are theoretical values; the actual values are slightly higher. This calculation formula can be found online with a simple search.
The theoretical value is 1.4625 tons, while our factory’s value is 1.556 tons
This is calculated using the direct reaction equation; chlorine gas may be produced as a by-product, so the yield will be lower
2NaCl + 2H2O = electrolysis = 2NaOH + H2↑ + Cl2↑; 2×40/1t = 58.5×2/a, from which it follows that the amount of salt required is a = 1.4625t.
