simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Pulverized Coal Combustion: the Influence of Flame Temperature and Coal Composition on Thermal and Fuel
A laboratory combustor was used to investigate the factors that influence the conversion of fuel nitrogen in coal during coal combustion. Fuel NO was isolated by experimentation utilizing Argon/Oxygen/Carbon Dioxide mixtures as the oxidant, and care was taken to compare cases with air at matched conditions. For both well mixed and slowly mixed flame types, fuel NO contributed over 75% of the to...
متن کاملFormation of CoAl layered double hydroxide on the boehmite surface and its role in tungstate sorption.
Sorption of tungstate on boehmite (γ-AlOOH) is increased by co-sorption with Co2+ over the near-neutral pH range. Batch uptake experiments show up to a 3-fold increase in tungstate uptake over the range WO42-=50-1000μmol/L compared to boehmite not treated with Co2+. Desorption experiments reveal a corresponding decrease in sorption reversibility for tungstate co-sorbed with Co2+. Reaction of bo...
متن کاملNew Insights on Saturn’s Formation from Its Nitrogen Isotopic Composition
The recent derivation of a lower limit for the 14N/15N ratio in Saturn’s ammonia, which is found to be consistent with the Jovian value, prompted us to revise models of Saturn’s formation using as constraints the supersolar abundances of heavy elements measured in its atmosphere. Here we find that it is possible to account for both Saturn’s chemical and isotopic compositions if one assumes the ...
متن کاملFundamental Models of Coal Char Formation and Combustion
The overall objective of this project is to carry out the fundamental research needed to develop a first-generation, structure-based model of coal char formation and combustion. Current models of char combustion and carbon burnout estimate char behavior from empirical relations based on parent coal properties. With the wide range of fuels of interest to modern combustion systems (international ...
