The effect of gas flaring involving some areas of the Niger Delta in Nigeria has been successfully carried out. Four villages were considered under this work: Aghigho, Obagi, Imeh and Edikan. An analysis of the volume of carbondioxide produced in each of the villages was carried out. The results of the analysis revealed that the effect of flaring associated gas on the environment is high based ...

The Technical University of Madrid (UPM) and REPSOL YPF are collaborating in the improvement in the estimation of the emiss ion factors for refinery flares. Flaring is an unavoidable process in the refining activity, both for safety reasons during upset processes (start-up, shut down, system blow-down) and when managing the disposal of waste gases with hydrocarbon from routine operations. The o...

The energy released in a solar flare is partitioned between thermal and nonthermal particle energy and lost to thermal conduction and radiation over a broad range of wavelengths. It is difficult to determine the conductive losses and the energy radiated at transition region temperatures during the impulsive phases of flares. We use UVCS measurements of O VI photons produced by 5 flares and subs...

During a presentation at the 2006 North Sea Flow Measurement Workshop on new and current flare metering technologies, infrared and other optical methods of gas flow measurement were referred to as “blue-sky” technology. The inference was that these technologies, whilst they might have merit, probably would not be available for some time, if ever. In reality, this is far from true, as at least o...

In sour gas flares,  content like any other components in inlet gas influences adiabatic flame temperature, which, in turn, impacts on the pollutant emission. Wherever flame temperature increases, the endothermic reaction between  and  is accelerated, which means higher  emission to the atmosphere. In this work, we developed an in-house MATLAB code to provide an environment for combustion calcu...

We calculate the timeand energy-dependent opacity of high-energy γ-rays attenuated by pairproduction interactions with accretion-flare photons that are scattered by gas and dust surrounding the nuclei of active galaxies. We show that the temporal behavior of the high-energy opacity cutoff can be used in conjunction with the time history of the accretion flare to determine the location of the γ-...
