I would like to ask about the alkali loss rate in the three-effect counter-current evaporation process

Thread Content

32% caustic soda is produced using the ion exchange membrane process, and it then enters a three-effect counter-current evaporation unit to yield 50% caustic soda. I would like to ask the experts: what is a reasonable percentage loss of caustic soda from input to output?

It can be basically ignored; the process condensate contains less than 15 ppm of alkali.
