Texte intégral

Résumé :

A gradient-independent model of gas fluxes was formulated and tested. The model is built on the relationship between gas flux and the time history of surface gas concentration, known as half-order derivative (HOD), when the transport of the gas in the boundary layer is described by a diffusion equation. The eddy-diffusivity of gas is parameterized based on the similarity theory of boundary layer turbulence combined with the MEP model of surface heat fluxes. Test of the new model using in-situ data of CO2 concentration and fluxes at several locations with diverse vegetation cover, geographic an

Résumé :

Currently, almost all new vehicles are equipped with airbags. A common type of airbag inflator is the Heated Gas Inflator (HGI). These inflators are cylindrical shaped canisters that are filled to very high pressures with a gaseous mixture of fuel and air. The mixture is ignited from one or both ends of the cylinder. The resulting high temperatures from combustion heats the excess air, which is then used to inflate the airbag. Once the mixture is ignited, large pressure waves form, traveling along the length of the tube. These waves, inherent to the design of the inflator, do not allow the use

Résumé :

Gas lift is one of the most common forms of artificial lift, particularly for offshore wells. This is due to its relative downhole simplicity, flexibility, reliability, and ability in operating over a wide range of flow rates with the limited well head space. Generally, Gas lift optimization can reduce the operating cost with increase in the Net Present Value (NPV) and maximization of the recovery from the asset. All of the previous researches have reported that conventional gas lift technologies’ designs have limitations on gas lift valve. Nonetheless, traditional gas lift technologies that w

Résumé :

In the last decade, shale reservoirs emerged as one of the fast growing hydrocarbon resources in the world unlocking vast reserves and reshaping the landscape of the oil and gas global market. Gas-condensate reservoirs represent an important part of these resources. The key feature of these reservoirs is the condensate banking which reduces significantly the well deliverability when the condensate forms in the reservoir below the dew point pressure. Although the condensate banking is a well-known problem in conventional reservoirs, the very low permeability of shale matrix and unavailability o

Résumé :

The reliabilities of the gas-path components (compressor, burners and turbines) of a gas turbine (GT) are usually high when compared with those of other GT systems such as fuel supply and control. However, in the event of forced outage, downtimes are normally high, giving a relatively low availability. The purpose of condition monitoring and fault diagnostics is to detect, isolate and assess (i.e. estimate quantitatively the magnitude of) the faults within a system, which in this case is the gas turbine.

The reaction of Water Gas Shift (WGS) plays a key role in the production of H2 or syngas, widely employed in the chemical industry. More than 90% of the H2 is currently produced by Steam Reforming (SR) of the natural gas or low molecular weight hydrocarbons, with an increasing role of its production from alternative sources such as the clean biogas (CBG), mixture of CH4 and CO2 obtained by elimination of S- and N-containing compounds from the gas mixture obtained by anaerobic fermentation of biomass.

Natural gas hydrates are solid crystalline substances found in the subsurface.

This work addresses the important issue of geomechanical stability in hydrate bearing sediments during different perturbations.

Elevated concentrations of ground-gases (CH4 and CO2) and VOCs in contaminated soil and water around the world pose significant risk both to human health and the environment.

Current ground-gas monitoring is often ineffective for determining their representative concentrations and fluxes – the two most important parameters necessary for ground-gas risk assessment. These failures of current monitoring may arise from its low temporal resolution. The recent ability to monitor at high temporal resolut

However, industry's understanding of wet gas flow phenomena in such a meter is limited and is therefore forced to accept large metering errors when existing correlations are used to take account of the liquid presence. Furthermore, these correlations all require an input value for the liquid flowrate. This information i

Résumé :

More than 120 depleted natural gas reservoirs in Alberta, Canada have been identified as potential sites for CO₂ storage at temperature and pressure conditions at which CO₂ may form gas hydrate. Reservoir simulations presented in the literature have demonstrated the feasibility of storing CO₂ in such reservoirs. In this thesis, the injection of CO₂ in a laboratory size reservoir (packed bed of silica particles) serving as a physical model for a depleted reservoir was studied. The hypothesis was that injecting CO₂ into the reservoir at gas hydrate formation conditions will be beneficial in term

Résumé :

This paper provides an update of our previous scaling relations between galaxy-integrated molecular gas masses, stellar masses, and star formation rates (SFRs), in the framework of the star formation main sequence (MS), with the main goal of testing for possible systematic effects. For this purpose our new study combines three independent methods of determining molecular gas masses from CO line fluxes, far-infrared dust spectral energy distributions, and similar to 1 mm dust photometry, in a large sample of 1444 star-forming galaxies between z = 0 and 4. The sample covers the stellar mass rang

Résumé :

There is an ongoing interest in the use of metal oxides as regenerable sorbents for the removal of sulphur dioxide from flue gases. Cerium oxide on alumina has been suggested but few experimental data are available, particularly for the regeneration process. It has been shown that the overall stoichiometry of regeneration with hydrogen can be split into twelve reaction steps. These were deduced from an inspection of rate data and analysis of partially reduced samples by volumetric methods and using Fourier transform infra red spectroscopy. Below about 828 K, the hydrolysis of intermediate sulp
