Technical Bulletin No. 0682: Volatile Organic Emissions from Pulp and Paper MIll Sources, Part VII – Sulfite Mills

NCASI/Weston Heated SUMMA Canister Method, NCASI Chilled Impinger Method, RTI Draft Method for aldehydes and ketones, and EPA Method 25A were used to determine the emissions of volatile organic ‘hazardous air pollutants’ (HAPs), selected other volatile organics, and total VOCS from a number of sources at one magnesium-base and one ammonia-base sulfite mill. The study showed that the volatile organic HAP emissions from two recovery furnaces, measured after the SO2 scrubbers and absorbers, were 1.8 lb/ton of red liquor solids (TRLS) and 6.
