Each company uses a different calculation method
I don’t understand what you mean. Normally, what comes out of the factory is a 10% sodium hypochlorite solution; adding alkali cannot result in a 12% sodium hypochlorite solution
Reply to 3# Jiangjiang: What I mean is, to produce a sodium hypochlorite solution with 10% effective chlorine content, what concentration of alkali is needed?
The percentage concentration of the base should be 3%-4% higher than that of sodium hypochlorite. To prepare 12% sodium hypochlorite, the concentration of the base is generally between 15% and 16%.
For the waste gas treatment in our chlor-alkali production, 10% alkali is used in the absorption towers, while 18% is used in the waste gas towers, which meets the requirements of the poster
Reply to 4# *ongpan2010: Is it 12% or 10%?
Reply 1# *ongpan2010: The standard solution is a 10% sodium hypochlorite solution, with the alkali concentration typically ranging from 15% to 16%. The reaction temperature should be below 45°C.
13- = 15% is acceptable as well; it depends on the value of your free base
