    摘要: A method of improving hydrocarbon recovery from oil sands, oil shale, and petroleum residues includes adding a polymeric or nonpolymeric processing aid capable of sequestering cations, such as the multivalent calcium, magnesium and iron cations. The hydrocarbons are preferably contacted with the processing aid before a primary separation of the hydrocarbons in order to increase bitumen recovery. A processing aid is provided in an effective amount to increase the liberation of the hydrocarbons from inorganic solids, particularly when the source is a poor processing ore. Preferred processing aids include citric acid or a polymeric acid selected from polyacrylic acid, polymethacrylic acid, salts of these acids, partial salts of these acids, and combinations thereof. The processing aids significantly increase the hydrocarbon recovery typically with concentrations less than 50 ppm and the polymeric processing aids can also provide beneficial flocculation of solids in tailings slurry.

    摘要: A novel microfluidic device has been developed to measure stability of thin liquid films of water in oil emulsions using electrochemical perturbation of interfaces. This new device can be utilized in rapid classification of de-emulsifiers used in petroleum industries. Although water/crude oil emulsions have been the primary focus of this research, this measurement platform can be used in other industries such as food, cosmetics and bio-engineering (bilayer lipid membranes) as well as environmental remediation of oil spills. The compact design of the device and replacement of the mechanical measurements such as pressure with electrical signal measurements contributes in substantial size reduction of the experimental platform so that it can be employed for onsite measurements in remote areas.
