Celulosa Arauco en Nueva Aldea (PCNA), dentro de sus gestiones ambientales, busca prevenir emanaciones de gases difusas al interior del recinto productivo. Durante las visitas a terreno, se detectó que el área de evaporadores presentaba emanaciones difusas puntuales durante operación normal. Debido a ello, se realizó un detallado estudio del área donde se descubrió la relación que tienen los lavados de los equipos concentradores de Licor Negro y las emanaciones difusas puntuales observadas. De acuerdo con lo anterior, se hicieron propuestas de mejoras de proceso e ingenieriles para lograr la eliminación de las emanaciones de vahos a la atmosfera.Pulp and Paper mills are dedicated to the production of cellulose and/or derivatives from the separation of the useful fibers extracted from wood, a process characterized by the emission of odoriferous gases, one of its main environmental impacts. To comply with the environmental standards set by Arauco, the Nueva Aldea plant (PCNA) looks to prevent the emissions of this type of diffuse gasses within its facility. During the terrain in visits, it was detected that the evaporators area had occasionally diffuse gas emissions during normal operation. Due to this, a detailed study of the area in question was carried out and complemented with terrain inspections and consultations to the operators. A link between the washings done to the equipment of black liquor concentration and the gaseous emanations from the atmospheric tanks associated with the Dilute Non-Condensable Gases (DNCG) system was discovered. In accordance with the above, proposals for engineering and process improvements were made to achieve the reduction of DNCG emissions into the atmosphere.esCC BY-NC-ND 4.0 DEED Attribution-NonCommercial-NoDerivs 4.0 InternationalCelulosaEvaporadoresThesis
