an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundw...

Petroleum refineries around the world have generated the solid wastes during the refining process and stocking of crude oil. Oily sludge leads to critical effects in the environment. The ecology of hydrocarbon degradation by microbial populations in the natural environment is reviewed, emphasizing the physical, chemical, and biological factors that contribute to the biodegradation of petroleum ...

The subject at hand is the technology of integrated use secondary combustible and thermal energy resources oil refining petrochemicals for power supply heat industrial residential urban areas. Currently, in through hydrocarbon gases are burned smokeless flares technological candles without practical electric industry. In production polyethylene, an average 230 t/h spent a flare altitude 105 m w...

Crude oil is a viscous dark liquid resource composed by mix of hydrocarbons which, after refining, used for the elaboration distinct products. A major concern that many petroleum components are highly toxic due to their teratogenic, hemotoxic, and carcinogenic effects, becoming an environmental on global scale, which must be solved through innovative, efficient, sustainable techniques. One most...

Cavitation, as a unique technology for influencing liquid substances, has attracted much attention in the oil refining industry. The capabilities of cavitation impact can initiate destruction molecular compounds liquid. At same time with large number successful experimental studies on treatment hydrocarbon raw materials, not been introduced Often impossibility implementation is based lack unifi...

The authors reviewed the statistics of winter diesel fuel consumption in Russian Federation for 2000–2017, revealed a positive growth rate. On this fact, relevance study was substantiated. complexity and importance refining process leads to need digitalization oil refineries. object is obtaining fuel, taking into account transport costs. subject on base constructing mathematical model delivery ...

this study sougth to the effect of occ pulp fractionation on produced paper strength properties improvement. using a pressure screen, occ pulp was devided to tow distinct fractions of accept ratio (short fibers) and reject ratio (long fibers) in accordance with optimum condition of fractionation based on the previous studies. in the next stage, long fiber stream was refined and recombined with ...

The article analyzes the factors that determine necessity of oil refinery construction in Kaliningrad region Russian Federation. assessment existing and prospective raw material base is performed. data for development feasibility study an are formed analyzed. Taking into account outdated on parameters hydrocarbon materials produced region, as well significant changes due to tendency develop off...
