AFONSO, Júlio Carlos  e  PEREIRA, Kátia da Silva. Analysis of sulfur compounds in petroleum refinery gaseous effluents. Quím. Nova [online]. 2010, vol.33, n.4, pp. 957-963. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422010000400035.

This work discusses an analytical procedure for analysis of sulfur compounds in treated petroleum refinery gaseous effluents using a sulfur chemiluminescence detector with dual plasma burner (SCD-DP). Calibration was accomplished by using standards and gaseous streams of known concentration of sulfur compounds. The response factors agree with the calibration table of ASTM standard D 5504 (2008). The detection range for sulfur compounds is in μg m^-3. The analytical procedure allowed the construction of a chromatographic chart of sulfur compounds present in several refinery gaseous effluents. SO₂ was the most difficult compound to be determined because of its high reactivity.
