Determination of sulfur speciation in industrial aerosols in an sulfur dioxide rich environment

Determination of sulfur speciation in industrial aerosols in an sulfur dioxide rich environment. Eatough, D. J. (Thermochem. Inst., Brigham Young Univ., Provo, UT, USA). Report, DOE/EV/10405-10; Order No. DE84004547, 44 pp. Avail. NTIS From: Energy Res. Abstr. 1984, 9(4), Abstr. No. 6586 (English) 1983. DOCUMENT TYPE: Report CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 80 Several anal. techniques for the detn. of org. S(IV) compds. in environmental samples were evaluated, the structure of org. S(IV) was identified as bis(hydroxymethyl) sulfone (I) [87954-49-2], new anal. procedures for detn. of di-Me [77-78-1] and Me sulfate [75-93-4] in particulate samples were developed, and these and existing techniques were applied to the study of the formation of SO42-, I, and methylated sulfate species in the flue lines and plumes of an oil- and a coal-fired power plant. Inorg. S(IV) compds. and I are generally not present in primary emissions from coal- or oil-fired plants but are formed in the plumes emitted by these facilities. The formation of SO42- from SO2(g) in the daytime follows kinetics which are 1st-order in SO2(g) and are temp.-dependent. The formation of SO42- from SO2(g) in the plume of an oil-fired power plant in a fog bank utilizes ~30% of the SO2/h. The fog bank reaction may be catalyzed by coemitted oxidants. Di-Me and(or) Me sulfate were shown to be present in both flue line and plume samples from coal- and oil-fired power plants. Methylated sulfates increase in concn. in aerosols during plume transport in the plumes of the power plants studied.
