Paper Abstract

Fourier-transform IR spectroscopic (FTIS) measurements have been performed at natural gas production facilities to study their potential to release hydrocarbons form vented and diffuse sources into the atmosphere. The measurements were realized using a commercial, moderate-resolution, mobile Fourier spectrometer. Effluent concentrations in the post- combustion zone above a flare are determined applying a multicomponent air pollution software which is based on radiative transfer line-by-line calculations and least- squares fit procedures. Emission rates are calculated on the basis of measured concentrations and known fuel flow rates to the flare. Diffuse emissions of the processing area are examined on the basis of open-path absorption measurements and Gaussian dispersion modeling. The flare combustion efficiencies were generally above 99 percent and indicate a rather small local environmental impact of methane emissions due to natural gas flaring. Contrary, comparatively, high diffuse emissions due to site leakages were determined which exceed the flare emissions by a factor of about 25.
