Abstract: The invention relates to agents reducing the hydrodynamic drag of a turbulent flow of petroleum products in the process of transportation in pipelines. The technical result of the solution involves the preservation of the polymer structure so that the polymer is more effective in reducing the hydrodynamic drag, grinding costs in the production of the DRA, the aggregation of the DRA while reducing the amount of the separating agent and the need to inject a smaller amount of the reagent to reduce the hydrodynamic drag. The specified technical result is produced due to the development of a reagent for reducing the hydrodynamic drag of hydrocarbon liquids in pipelines, which consists of the first and the second component, in which case the first component comprises the particles of polyalphaolefin or polyacrylate, the second component is an anti-agglomerating agent.

Abstract: An experimental method for coal desulfurization and deashing using permeation and solvating power of a supercritical fluid includes the following steps. The coal sample is ground and loaded into an extraction kettle with a cover. An inlet valve and an outlet valve of the extraction kettle are opened to circulate the supercritical CO2 fluid in the extraction kettle. The extraction kettle is sealed. By adjusting a temperature and a pressure in the extraction kettle, the supercritical CO2 fluid is kept at its critical point and permeates the coal sample to dissolve organic sulfur, inorganic sulfur and ash in the coal sample. The extraction kettle is depressurized, and the temperature in the extraction kettle is adjusted to gasify the supercritical CO2 fluid. The organic sulfur, the inorganic sulfur and part of the ash are separated from the supercritical CO2 fluid and precipitated at a bottom of the extraction kettle.

Abstract: For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. Marine shipping use of high sulfur bunker oils is reported as largest source of worldwide transportation SOx emissions. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can use these fuels to generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.

Specifically, the subject invention provides cultivated yeast products, which can be applied to oil and/or oil and gas production equipment to improve production and increase the economic value of heavy crude oil by, for example, upgrading heavy oils and/or converting heavy hydrocarbon substances, such as asphalts, asphaltenes, tars, bitumens and/or petcokes into lighter hydrocarbon substances.

Abstract: For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. Marine shipping use of high sulfur bunker oils is reported as largest source of world-wide transportation SOx emissions.
