Crude oil fouling of the equipment surfaces is a troublesome issue which leads to operating difficulties, economic penalties, increased environmental impacts, and health and safety hazards in petroleum industry. With a rough estimation, a minimum cost of equal to 4 million barrels of oil/year is required to be invested to offset the costs of crude oil fouling in Pre-heat Trains of Iranian oil r...

Abstract Mayonnaise is semi-solid stable emulsion of vegetable oil, egg yolk or whole egg, vinegar or lemon juice, salt seasonings and sugars and dextrose. Oil is used in mayonnaise as energy source and for smooth texture. Mayonnaise was prepared by using different concentrations of corn oil (235 ml, 240ml, 245 ml, 250 ml and 255 ml).Firstly all the ingredients were weighed by using the electri...

Oil spills from tanker or oil well have detrimental effects on environment and economy. One of the most economical and efficient methods for oil spill clean-up is mechanical extraction by sorbents which are not only the safest methods but also the least expensive of spill control. The potential use of agricultural by-products such as corn silk for adsorbent of crude oil from water systems was p...

Dispersants are a preapproved chemical response agent for oil spills off portions of the U.S. coastline, including the Texas-Louisiana coast. However, questions persist regarding potential environmental risks of dispersant applications in nearshore regions (within three nautical miles of the shoreline) that support dense populations of marine organisms and are prone to spills resulting from hum...

Environmental contamination by petroleum hydrocarbons, mainly crude oil waste from refineries, is becoming prevalent worldwide. This study investigates the bioremediation of water contaminated with crude oil waste. Bacillus salamalaya 139SI, a bacterium isolated from a private farm soil in the Kuala Selangor in Malaysia, was found to be a potential degrader of crude oil waste. When a microbial ...

Oil spills from pipeline ruptures are a major source of terrestrial petroleum pollution in cold regions. However, our knowledge of the bacterial response to crude oil contamination in cold regions remains to be further expanded, especially in terms of community shifts and potential development of hydrocarbon degraders. In this study we investigated changes of microbial diversity, population siz...

a r t i c l e i n f o A large part of government revenues in Russia comes from royalties and export taxes on crude oil, oil products, and gas. Recently, the Russian government has considered reducing export taxes on crude oil and oil products compensated by an increase in the royalty on crude oil. The objective of the paper is to analyse the economy-wide effects of this proposal. Moreover, a hy...

Microbial Enhanced Oil Recovery (MEOR) is a potential technology for residual heavy oil recovery. Many heavy oil fields in Oman and elsewhere have difficulty in crude oil recovery because it is expensive due to its high viscosity. Indigenous microbes are capable of improving the fluidity of heavy oil, by changing its high viscosity and producing lighter oil fractions. Many spore-forming bacteri...
