Definitions
- a hydroxide preferably a sodium hydroxide solution
- a hydroxide solution may be supplied to the collecting vessels 19, 20 and 21 through conduits 26, 27 and 28, respectively, conducting alkali from a supply (not shown), which pre ⁇ ferably is common all the conduits.
- the supply of sodium- hydroxide solution for adjusting the pH of the absorption solution is regulated on the basis of the measured pH values of the solutions in the collecting vessels 19, 20 and 21 (not shown).
