摘要： Oxidative compositions and processes that preserve and enhance the brightness and improve color of pulp or paper when applied during different stages of the papermaking process are identified. The oxidative composition and method maintains and/or enhances brightness, prevents yellowing, and enhances the performance of paper products. Used in combination with optical brighteners and/or chelants the oxidative agents produce a synergistic effect not previously identified in the paper process.

摘要： The invention is directed towards methods, compositions, and apparatus for accurately detecting the presence and amounts of contaminants in wastewater. The method comprises the steps of adding to a volume of wastewater at least one tracer molecule, observing the tracer for indications of particular contaminants, conducting at least one second form of contamination detection, and interrelating the two measured properties to identify the specific composition of the contamination. Using a tracer molecule allows for the detection of otherwise hard to detect oils and grease. Use of the second method however compensates for tracer interfering contaminants and allows for more accurate readings. The invention includes feeding of functional chemicals in response to the detections and conducting the detections online and continuously.

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： The invention provides a more effective optical brightener composition for coating paper substrates. The invention includes an optical brightening agent (OBA) and a glycerol based polymer. This combination results in a composition that provides a surprisingly large whitening effect and does not degrade the shade of the paper. As a result extremely high degrees of whiteness can be achieved without being frustrated by the greening effect.
