In the rubber industry, plasticizers for rubber compounds mainly consist of petroleum derivatives. Consequently, the rubber industry is in constant competition with many petroleum consumers. This competition places an economic strain on rubber companies such as HEXPOL RUBBER COMPOUNDING L.L.C. In order to alleviate this strain, natural oil alternatives to petroleum plasticizers are of novel res...

Bioremoval and bioreduction activities of hydrocarbon (diesel) isolation from environmental samples were studied by the activity of biosurfactant production, and calculating emulsification index, gravimetric, and FTIR analysis along with the estimation of bacterial biomass. Sample from soil near petrol, diesel pumps and water sample from Thesjaswini River near Padannakad, Kasaragod, Kerala, Ind...

A rapid, reliable method for the routine detection and quantification of biomarkers in petroleum was developed using the Agilent 7890A/7000A Series Triple Quadrupole GC/MS with backflushing using a Pressure Controlled Tee configuration. In a single run, diverse biomarkers from several transitions can be detected, confirmed, and quantified at levels as low as 2 ppm, with RSDs well below 5%. This...

Results: The findings revealed that petroleum ether extracts possess excellent anti-lice activity .In 15 % concentration seed oil is able to kill 100% lice and 10 and 15 % concentration of seed oil makes nits unable to survive, results were well comparable with standard i.e benzoyl benzoate (25% w/v) as its 10% and 20% concentrations are able to kill 100% lice and deactivated nits. These result...

Petroleum-oil sprays and fogs are used increasingly to control insect pests of economic plants. These oils are useful in controlling the aphid vectors of potato virus, but it is first necessary to learn which oils are tolerated by potato leaves. Hence, undiluted oils and cresoap emulsions of petroleum oils were tested on potato leaves to determine: (1) The rates of oil penetration into leaves; ...

various adjuvants carry out different functions depending on the herbicides types and the target species. outdoor pot experiments were conducted to evaluate the effects of three post-emergence herbicides, namely, clodinafop-propargyl, haloxyfop-p-methyl, and difenzoquat-methyl-sulfate, as influenced by two adjuvants, on wild oat (avena ludoviciana durieu.) control. the study was carried out at ...

Nutrient addition has been proved to be an effective strategy to enhance oil biodegradation in marine shorelines. To determine the optimal range of nutrient concentrations in the bioremediation of oil-polluted beaches, nitrate was added to the simulated shoreline models in the initial concentration of 1, 5 and 10 mg/L. Whenever the NO3-N concentration declined to 70% of its original value, addi...

For several decades, petroleum has been a commodity of vital impor-tance to the global economy, in which a number of interesting marketphenomena has occurred. This monograph represents my efforts todescribe several of these phenomenon, along with a few other elementsof the oil market. My focus is on elements related to the extractionof petroleum, and the interactions between...

Absorption and fluorescence properties of 4 hydraulic oils (3 biological and 1 petroleum-based) were investigated. In-situ LIF (laser-induced fluorescence) analysis of the oils on a brown sandy loam soil was performed. With calibration, quantitative detection was achieved. Estimated limits of detection were below ca. 500 mg/kg for the petroleum-based oil and ca. 2000 mg/kg for one biological oi...
