Mapping of sodium/sulphur-balances. A study on losses in a

Sulphate pulp is produced by treating wood chips with alkaline chemicals at elevated temperature in the so called cooking process in a pulp mill. The active cooking chemicals are sodium hydroxide (NaOH) and sodium sulphide (Na2S). After the cooking the pulp goes to the bleaching plant for further treatment and the cooking liquor, called black liquor goes to recovery system.
