Abstract
An improvement is provided in a process for preparing, under reducing conditions, cooking liquors for sulphate pulp cooking. The black liquor which is formed in the cooking process is fed, after evaporation, completely or partly to a reactor operating at increased temperature. The increased temperature is obtained by energy which is supplied from an external heat source and/or release of energy from the black liquor, thereby to form a melt of sodium sulphide. The melt then is withdrawn to be further processed to cooking liquor.
The melt, and the whole or part of at least one of sulphur-containing, sulphur-and sodium-containing materials which are present in the pulp mill including sulphur-containing, and sodium- and sulphur-containing make-up chemicals used for the total chemicals balance of the pulp mill, are fed to the reactor in such a way that the mole ratio of sodium to sulphur in the total mixture which is fed to the reactor is within the range of from 1.5 to 4.
The melt, and the whole or part of at least one of sulphur-containing, sulphur-and sodium-containing materials which are present in the pulp mill including sulphur-containing, and sodium- and sulphur-containing make-up chemicals used for the total chemicals balance of the pulp mill, are fed to the reactor in such a way that the mole ratio of sodium to sulphur in the total mixture which is fed to the reactor is within the range of from 1.5 to 4.
