Objectives. Recently, there has been a tendency to increase the volume of high-viscosity heavy oils in total oil produced. The processing these requires new technological approaches. This task is closely related need depth refining. Among approaches proposed solve problems, mechanochemical activation, which based on cavitation effect produced by ultrasonic or hydrodynamic methods, suggested. st...
The growth of the fleet rolling stock motor transport increases requirements for road safety, which is largely determined by operational reliability and technical condition components mechanisms chassis. In many countries, large-scale studies are being conducted related to problems improving quality, durability vehicles technological equipment based on repair kits, as well manufacturing assembl...
We present a coherent and unified group of general explanations for the various phase transitions, which may occur in the seven naturally occurring petroleum fluids with emphasis on their heavy organics. The seven petroleum fluids include, in the order of their fluidity, natural gas, near-critical gas-condensate, light crude, intermediate crude, heavy oil, tar sand and oil shale. At first the n...
After the World War II, the world economy was disrupted and changed due to oil and its prices. The research in this paper presents the basic statistical features and economic characteristics of the Gulf economy. The main features of the Gulf economies and its heavy dependence on oil exports, its dualism between modern and traditional sectors and its rapidly increasing affluences are particularl...
A destoner fractionation process was used to separate distillers dried grains with solubles (DDGS) into streams with various compositions. Results showed that destoner fractionation was somewhat efficient and effective. Runs with 8° angle and 27.5 percent air flow resulted in the highest value of protein and oil, which the light fraction had 28.15% protein, 10.50% oil, while the heavy fraction...
From the mid-1980s until 1994, U.S. oil and gas exploration and production steadily declined, forcing a significant increase in U.S. imports of crude oil. For example, in 1994, the United States imported more than 50 percent of the nation's total demand, which was the highest level since 1990. To economically develop U.S. oil production in deep-water locations, the industry needed strong, light...
This study focused on the determination of detailed grain morphology using SEM technology on some Athabasca oil sands samples obtained from the Upper McMurray Formation in the Manville Group which occurs in the Western Canada Sedimentary Basin. The research was carried out using scientific techniques to understand grain morphology—being a major effect in discerning reservoir quality—a factor wh...
