Abstract |
A manual method for measuring reduced sulfur compounds in Kraft pulp mill and sulfur recovery plant emissions was evaluated. The method involves removing SO2 from the gas stream (if present) with a citric acid-potassium citrate buffer, that passes reduced sulfur compounds; thermal oxidation of all reduced sulfur compounds to SO2; collection of the SO2 in H2O2; and a titrimetric analysis of the H2O2 for SO42-. A heated filter removes a alkaline particulate matter that would produce a negative interference if absorbed by the buffer. The method is unbiased provided that non-regulated reduced sulfur compounds such as COS (Kraft pulp mills) and thiophene (sulfur recovery plants) are not present in the emissions. If present, these compounds will be oxidized to SO2 and thereby produce a positive bias. The precision of the method ranges from 1 to 7% relative standard diviation. |
