Combustion of predominantly hydrocarbon gas results in the production of nitrogen oxides (NOx). Here, we present a large field data set of in situ sampling of real world flares, quantifying flaring NOx production in major U.S. oil production regions: the Bakken, Eagle Ford, and Permian.

Thermal NO x formation, which is highly temperature dependent, is recognized as the most relevant source when combusting natural gas. Fuel NO x tends to dominate during the combustion of fuels, such as coal, which have a significant nitrogen content, particularly when burned in combustors designed to minimise thermal NO x .

Jul 22, 2024 · We implemented a condensed chemistry scheme to investigate how the emitted NOx (95 % as NO) is converted to NO2 in the plume. To use NOx as a proxy for CO2 emission, information about its atmospheric lifetime and the fraction of NOx present as NO2 is required.

------- ABSTRACT The report gives results of a study to relate ground level NO2 concen- trations to NOx emissions (N02/N0x ratio) in plumes from six large power plants in the Chicago area, using a photostationary state reactive Gaussian plume model.

This bulletin explains why NOx are important air pollutants and how NOx are formed and react in the atmosphere. This bulletin also discusses the principles on which all NOx

It is important to note that, under the right conditions, power plant plumes may travel relatively long distances overnight with little loss of VOC, NO-and NO2. ...

Yellow plumes can sometimes be observed at the exhaust of diesel and natural gas generators during certain operating conditions (see Figure 1). This is a visible representation of nitrogen dioxide (NO2) present in the exhaust gasses from an engine.

Jan 1, 2005 · Through a series of computational studies, carbon monoxide has been identified as an important promoter of NO oxidation to NO2 in combustion turbine exhaust gas at intermediate temperatures (450...

This study makes use of a Gaussian Plume model to determine the concentration levels of NOx as a function of distance in the populated areas surrounding a 60,000 horsepower (HP) natural gas compressor station proposed for construction in Northwest Davidson County, Tennessee.

We developed an Integrated Plume Dispersion Model of NOx with Chemical Reactions and examined the performance of the model. The model is based on Gaussian plume dispersion model in integrated forms, and atmospheric di usion and chem-
