In order to help one judge the friction properties of lubricating oils without tests, this paper intends establish correlation between characteristic parameters and properties. The elastohydrodynamic boundary poly alpha olefin (PAO) synthetic oil, polyol ester oil paraffin-based mineral were tested using a Mini-Traction Machine. Fourier transform infrared microscopy is used identify material ch...

Miscible gas injection, as an Enhanced Oil Recovery (EOR) method, can improve the recovery factor by swelling the residual oil and phasing out the interfacial tension [1]. However, the sweep efficiency of miscible gas injection is not satisfactory because of conformance problems, such as viscous fingering, channelling and gravity override [2]. Foam can solve the problems associated with gas inj...

Materials. Alkali-refined soybean oil was obtained from Riceland Foods (Stuttgart, AR) and Archer Daniels Midland (Decatur, IL). Alkali-refined canola and cottonseed oils were purchased from Bunge Oil (Bradley. IL). Alkalirefined sunflower oil was obtained from Archer Daniels Midland. Alkali-refined safflower oil was obtained from Pacific Anchor Chemical Co. (Cumberland, RI). Polystyrene standa...

The rapid expansion of oil sands production in northern Alberta is under scrutiny worldwide due to concerns about its environmental, social, and economic impacts. Environmental concerns include climate change impacts from CO2 emissionsalongwithmore local environmental impacts such as dead birds, cancer clusters, and destruction of boreal forests.Within Canada, oil sands have become an important...

This paper reports on the assessment of the quality and quantity of castor oil from castor seeds collected from different regions in Tanzania. The castor seeds from Arusha, Dar es Salaam, Dodoma, Iringa, Kagera and Morogoro regions in Tanzania were extracted by Soxhlet method using n-hexane and the oil yields were determined. The yields were 52.78%, 49.95%, 47.89%, 44.23%, 43.71% and 43.69% for...

The ability to prepare solid surfaces with well-controlled superhydrophobic and superoleophilic properties is of paramount importance to water-oil separation technology. Herein, we successfully prepared superhydrophobic-superoleophilic membranes by single-step deposition of polystyrene (PS) nanofibers onto a stainless steel mesh via electrospinning. The contact angles of diesel and water on the...
