Biological Odour TreatmentEmissions from Pulping

Biological Odour Treatment: Emissions from Pulping [The manufacture of pulp for paper and board employs mechanical and chemical methods.

Abstract

[The manufacture of pulp for paper and board employs mechanical and chemical methods. Chemical pulping is used on most papers produced commercially in the world today. The Kraft process is the most dominant chemical pulping process worldwide. The problem of kraft mill odour originating from the sulphide in the white liquor in the initial pulping has long been an environmental and public relations issue for the pulp and paper industry. The kraft mill odour is caused predominantly by malodourous reduced sulphur compounds, or total reduced sulphur compounds namely, methyl mercaptan, dimethylsulphide, dimethyldisulphide and hydrogen sulphide. Reduction of odourous gas emissions in kraft mills will significantly improve the environmental competitiveness of the pulp and paper industry, and will also improve public relations with their respective surrounding communities. When it is more economically feasible, odour reduction, instead of odour elimination, can improve significantly the air quality and the environment of a kraft mill, since it will reduce the radius of the area being impacted by the odour emission. Typical characteristics of the gaseous emissions from kraft pulp mill, neutral sulphite semi-chemical (NSSC) pulping, sulphites and mechanical pulping are presented in this chapter.]
