A Novel Technique for Removing Finely Dispersed Particles from Tailings

Ware W., Ashcraft N., Soane D., Soane Energy, US

Traditional oil, gas, and mining industries rely heavily on the use of water as a means to aid in the recovery of natural resources. Often times these activities, either through mechanical shear or chemical additives, [...]

Analysis the optimal damper angle for a furnace to reduce the energy cost and CO2 emission

Jou C.-J.G., Kaohsiung First University of Science and Technology, TW

Optimal values for conducting a full-scale plant operation are usually obtained based on experience without the support of theoretical quantitative analyses. In this research, the Grey Relational Analysis method is implemented to develop a model [...]

Rapid Hydrate Formation, A Process for Transport and Storage of Natural Gas

Taylor C.E., Brown T., Unione A., U.S. Department of Energy, US

Experimental results from the Na¬tional Energy Technology Laboratory (NETL) show that rapid and continu¬ous formation of methane hydrate, as well as other gas-derived hydrates is achievable. The goal of this technology is to pro¬vide a [...]

The Retention of Silica Nanoparticles at Oil/Water Interface

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

We investigate the retention of silica nanoparticles at water/crude oil interface. Silica nanoparticles with three different surfaces (unmodified, surface modified with anionic (sulfonate), or nonionic (PEG) surfactant) are used. Interfacial tension (IFT) measurements provide us [...]

Application of Salts Free of Chlorine as Inhibitors of Clays in Aqueous Drilling Fluids

Lucena D.V., Borges P.R., Amorim L.V., Lira H.L., UniversidadeFederal de Campina Grande, BR

At present, concern with the environment damage and the costs involved in the disposing of contaminated cuttings have led to find drilling fluids water based, but during the well drilling it is common the presence [...]

Modified Nanoclays: An Approach to Stabilizing Drilling Fluids Rheology at High Temperature

Abdo J., Haneef M.D., Sultan Qaboos University, OM

There is a lot heard about growing dearth of conventional oil reservoirs in recent times. The depletion of ‘easy oil’ is a major concern for the drilling industry that is urging the technologists to push [...]

Clean Coal by Oxyacidification

Gokturk H., Ecoken, US

US, China and many other industrialized economies rely heavily on coal for electricity generation. Unfortunately coal has become a controversial fuel due to various pollutants and carbon dioxide (CO2) generated during combustion. Regulated pollutants include [...]

Novel CNT-polymer Nanocomposites used in Oilfield for High Temperature, High Pressure Sealing

Ito M., Schlumberger, JP

A novel sealing system base on MWNT (multiwalletd carbon nanotubes) and polymer nanocomposites was developed for the use in the exploration and development of hotter, deeper reservoirs. Fully dispersed and better bonding are two critical [...]

Metal-doped Photocatalysts to Reduce Carbon Dioxide in Ethanolamine Solution for Methane Production

Wu H-Y, Wu J.C.S., Bai H., Wu H-Y, Wu J.C.S., National Chiao Tung University, TW

Photocatalytic reduction of carbon dioxide (CO2) to form valuable energy source of methane in the ethanolamine (MEA) solution is investigated in this study. The TiO2 photocatalysts were prepared by doping with nano-sized metals (Fe, Zn, [...]

Reducing Material Waste in Biodiesel Production through Multi-Energy Optimized Processing

Kropf M.M., The Pennsylvania State University, US

Multi-Energy Optimized Processing is a patented green chemical processing technique which substitutes focused energy for hazardous chemicals to achieve efficient fuel conversions. Applied to bio diesel production, this technology reduces material waste in the form [...]
