摘要： A method of monitoring and inhibiting scale precipitation and deposition from spent liquor in pulp mill evaporators and concentrators is disclosed. The method includes connecting a black liquor deposition monitor to a pulp mill evaporator or concentrator and measuring the thermal conductivity on the outer surface of the monitor. A controller interprets the measured thermal conductivity and determines a level of scale deposition. If the level of scale deposition is above a predetermined level, the controller is operable to introduce a scale-inhibiting composition to the spent liquor. The scale-inhibiting composition may include organic polycarboxylic acids; organic fatty acids; low molecular weight and polymeric aromatic acids; organic acid esters, anhydrides, and amides; low molecular weight and polymeric aliphatic and aromatic sulfonic acids; and low molecular weight and polymeric amines; and any combinations.

摘要： Mechanical or Chemical pulp is treated with about 0.01 weight % to about 5 weight % of a Mixture. The Mixture is water; diethylenetriaminepentakis (methyl) phosphonic acid or its known salts; polyacrylic acid or its known salts; and optionally one or more inert compounds. This Mixture acts to either maintain the brightness level of the pulp at the target level or to increase the brightness level of the pulp. In addition the Mixture allows for maintaining the pulp at the target level of brightness even when the amounts of other ingredients, such as hydrogen peroxide, hydrosulfite, sodium silicate and magnesium, that are typically added to the pulp, are reduced.
