Abstract

Shell Research Ltd has been using an IR differential absorption LIDAR (DIAL) facility for about two years to measure the emission rates (fluxes) of VOCs from petroleum industry process units. This paper describes the measurement, flux calculation and data display procedures used. Careful system setup and tuning plus the use of appropriate calculation procedures are needed to obtain accurate measurements. The factors that affect flux measurement accuracy and detection limits under practical conditions are discussed.
