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： Enzymatic methods are provided for determining the surface triglycerides content in a sample of wood pulp. The methods preferably comprise reacting triglycerides which are present on the surface of the wood pulp fibers in the sample in the presence of a lipase to form glycerol and fatty acids, and then determining the difference between the amount of free glycerol present in the sample and the amount of glycerol formed from said triglycerides. The method is useful as a quick, portable, accurate, and low cost assay for assessing the amount of triglycerides present at various sample points in pulp and paper mills, which advantageously serves as a diagnostic tool for use in controlling the undesirable deposition of pitch during the papermaking process.

摘要： A method for reducing or eliminating the formation of salt scale upon process equipment caused by precipitation of insoluble salts during the bleaching of pulp. The pulp is subjected to a bleaching sequence which includes a plurality of pulp treatment steps, wherein at least one pulp treatment step is conducted under alkaline conditions and at least one pulp treatment step is conducted under acidic conditions. A filtrate stream which contains dissolved insoluble salts therein is thus generated, and at least a portion of the filtrate stream is combined with an alkaline stream and pulp to cause the salts to associate with the pulp, thus removing the salts from the filtrate stream to reduce or eliminate the formation of salt scale upon process equipment during the bleaching of the pulp.
