Quantification of VOC emissions using tracer dispersion, Mobile Extractive FTIR (MEFTIR) and Mobile Whitecell-DOAS (MWDOAS)

The application of Mobile Extractive FTIR and Mobile Whitecell Differential Optical Absorption Spectroscopy to establish VOC emission factors for tank filling operations and for discharge of petroleum products to trucks and vessels is described. An example of VOC emissions related to discharge of gasoline to trucks at a depot, which was connected to vapor recovery unit, is presented. Discharge of gasoline to ships was found to have an alkane (CH4 emission factor of about 5x10-5 kg emitted VOC/kg discharged product, comparable to the corresponding for trucks. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
