Technical Bulletin No. 0371: TGNMO Emission Potential from Kraft Process Heavy Black Liquor Oxidizers Operated on Liquors from Western Wood Species

This technical bulletin described the level of VOC emissions from two heavy black liquor oxidizers operated on liquors from western wood species. The study showed the VOC emissions to average 0.45 lb/ton pulp, ranging from 0.33 to 0.58 lb/ton pulp. This represented about one-half the amount of VOC emissions from a direct contact evaporator.
