Abstract: A method and apparatus for the treatment of pulp mill condensates is described. A hollow fiber contactor, incorporating a hydrophobic membrane, was used to remove several undesirable compounds from pulp mill condensates. For example, TRS compounds and SO2 were efficiently stripped from kraft and sulphite mill evaporator condensates, respectively. Methanol was also removed from kraft mill condensates but at a lower efficiency than TRS. Furthermore, other undesirable compounds found in condensates of pulp mills that contribute to the BOD and COD loading to effluent treatment systems were also removed. These contactors are cost effective since air, vacuum or a suitable solvent or scrubbing solution can be used as the stripping medium to drive off through the membrane several undesirable compounds from the feed solution. The undesirable compounds removed can thus be burned in the recovery boiler, lime kiln or a dedicated boiler.

Abstract: Acid hydrolysis of biomass is an important step for releasing the component sugars before converting them to fuels and/or biochemicals. During such a process, a significant amount of mineral acid, such as sulfuric acid, is used. In most cases, the residual acid is neutralized with lime before the sugar conversion step. By doing so, a waste calcium sulphate stream is generated and sent to disposal. The efficient separation of acid from the sugars would allow the recycle of the acid and make the entire process more economically viable. We found that a resin bed packed with an acid retardation resin can be used to achieve an efficient separation (i.e. 98.5% recovery of the acid) of the sulfuric acid from the sugars. The resin bed can be simply regenerated with water.

Abstract: A water-based process was developed for the synthesis of aminated lignin copolymers with high MW, thermal stability and solubility in water over a wide range of p H values. The cationic lignin copolymer described herein comprises: a grafting ratio of (weight of cationic amine compound) / (weight of lignin) of 70 to 200% and a charge density of +1.4-3.0 meq/g. This cationic lignin copolymer can be used as a flocculant in numerous wastewater streams including municipal and industrial systems and sludge dewatering in the pulp & paper, mining and oil industries.

Abstract: LA MAYORÍA DE LOS PROCESOS QUE SE PROPONEN Y/O USAN EN LA ACTUALIDAD PARA LA PRODUCCIÓN DE LIGNINA A PARTIR DE LICORES NEGROS KRAFT O A LA SODA SON CAPACES DE PRODUCIR DOS TIPOS PRINCIPALES DE LIGNINA: LIGNINA DE CONTENIDO RESIDUAL ALTO (HRC) Y LIGNINA DE CONTENIDO RESIDUAL BAJO (LRC). DE MANERA SORPRENDENTE, SE DESCUBRIÓ QUE LA LIGNINA HRC ES UN INGREDIENTE ADECUADO EN ADHESIVOS ALCALINOS, PARTICULARMENTE ADHESIVOS DE MADERA DE TIPO FENÓLICO (P. EJ., RESINAS DE RESOL). ESTE BIOMATERIAL ES ECOLÓGICO Y TIENE UN COSTO NOTABLEMENTE BAJO, LO CUAL LO VUELVE UN MATERIAL VIABLE DESDE EL PUNTO DE VISTA INDUSTRIAL A USAR COMO UN INGREDIENTE NOVEDOSO Y FUNDAMENTAL EN LOS ADHESIVOS FENÓLICOS PARA LA FABRICACIÓN DE CONTRACHAPADO DE GRADO EXTERIOR, CHAPAS DE MADERA LAMINADA, TABLEROS DE VIRUTA ORIENTADA (OSB) Y OTROS PRODUCTOS DE MADERA -ESTO SE DEMOSTRÓ CON ÉXITO EN UNA CANTIDAD DE EXPERIMENTOS DE LABORATORIO ASÍ COMO VARIOS ENSAYOS DE FÁBRICA-. EN LA PRESENTE SE DESCRIBE LA COMPOSICIÓN, PREPARACIÓN Y APLICACIÓN DE ESOS ADHESIVOS DE MADERA.

Abstract: The present invention describes a process and system of producing methanol from methanol condensates. In a preferred embodiment the condensates are biomethanol condensates from chemical pulp mills and various waste sources used to produce a purified biomethanol. Pulp condensates are rich in methanol and contain many other contaminants. Presently, most chemical pulp mills, such as Kraft pulp mills use steam stripping to remove and concentrate the methanol and burn the methanol onsite along with the contaminants. A combination of treatments that include air stripping, steam stripping, distillation and reverse osmosis is described to obtain purified biomethanol suitable for sale or use on site.

Abstract: Durante la producción de celulosa nanocristalina (NCC), se usa una cantidad considerable de ácido sulfúrico; después de la separación de la NCC, la solución restante contiene azúcares y ácido sulfúrico residual; los azúcares están en las formas monomérica y oligomérica; para reducir el costo de la producción de NCC y para producir otros productos con valor agregado, la corriente de ácido agotado puede ser fraccionada en oligómeros de azúcar, monómeros de azúcar y ácido; el ácido puede ser recirculado hacia el procedimiento de fabricación de NCC después de la concentración; los monómeros de azúcar y los oligómeros de azúcar pueden usarse para la fabricación de otros químicos valiosos; puede usarse nanofiltración por membrana para lograr este objetivo; se usó una membrana polimérica con una limitación de peso molecular en la escala de 200 Daltons; mediante el uso de este procedimiento, la mayor parte del ácido fue recuperado en el producto permeado, mientras que los azúcares fueron concentrados en una corriente más pequeña; el nivel de azúcar en la corriente separada de ácido/producto permeado fue sólo aproximadamente 3% de la concentración original; puede usarse una segunda etapa de filtración por membrana, para separar los azúcares monoméricos de los azúcares oligoméricos; las dos corrientes de azúcar pueden usarse en diferentes aplicaciones para obtener productos con valor agregado.

Abstract: Steam stripper off gas from chemical pulp mills, for example kraft or sulphite pulp mills is rich in methanol and totally reduced sulphur (TRS) compounds. This gaseous stream is usually burned to avoid further handling of this TRS-rich, odorous stream. We found that once this gaseous stream is condensed, it can be used as a reducing agent in the chlorine dioxide generator, in place of purchased methanol. Surprisingly, we found that, in addition to the methanol component, the TRS components act as reducing agents during the production of chlorine dioxide or, at the very least, do not consume chlorine dioxide. The use of this stream in the ClO2 generator will allow pulp mills to reduce or eliminate the consumption of purchased methanol while providing a new approach to deal with TRS compounds in the chlorine dioxide generator rather than employing a dedicated TRS incinerator or any other combustion device.
