AbstractSky-LOSA, an extension of Line-of-Sight Attenuation (LOSA) that is commonly used in laboratory-scale experiments for soot concentration measurements, was applied to a small flare in Poza Rica, Mexico. An average soot emission rate of 057 g/sec was obtained from 1.5 min of data. The uncertainty associated to velocity measurement was studied. Using a single ensemble averaged velocity in place of instantaneous velocity measurements synchronized with transmissivity measurements led to a 13% underestimation of the average soot emission rate. Uncertainty associated with integration along the optical axis was 7%. Sky-LOSA remains promising for investigation of particulate matter emissions in flares. This is an abstract of a paper presented at the 105th AWMA Annual Conference and Exhibition (San Antonio, TX 6/19-22/2012).
