Resource Abstract

A detailed study was conducted to evaluate the relative impact different equipment and operations have on air pollutants and associated permitting requirements on well sites. Emissions of criteria pollutants from wellsite equipment were estimated using the North Dakota Department of Environmental Quality (DEQ) emission tool with specific emphasis on combustion equipment. Analysis included estimating emissions from standard flares with 98% destruction efficiency, high efficiency flares achieving 99.5% destruction efficiency, and gas fired electrical generators. The results of the analysis illustrate the reduction in volatile organic compound (VOC) emissions that can be achieved when natural gas liquids are removed from the associated gas stream, prior to combustion in a flare or generator.
