Petroleum substances are the main source of pollutants stored in old waste pits. They cause degradation of biological life in the area of storage. The aim of this article is to present laboratory research on petroleum pollutant biodegradation. The hydrocarbon contaminants in old drilling wastes came from the Graby-19 waste pit. The tests included basic bioremediation and inoculation with a biop...
The present study was aimed at evaluation of the anti-inflammatory, analgesic and antipyretic activities of petroleum ether and ethanolic extract of aerial parts of Mollugo pentaphylla Linn. In experimental standard models. The results showed that the ethanolic extract significantly reduce the edema induced by carrageenan within 1 to 3 hrs. post dosing and Cotton-pellet induced granuloma models...
The efficiency of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains isolated from a petroleum contaminated soil sample from North-East India was compared for the biodegradation of crude petroleum-oil hydrocarbons in soil and shake flask study. These bacterial strains could utilize crude petroleum-oil hydrocarbons as sole source of carbon and energy. Bioaugmentation of TPH cont...
Near-infrared (NIR) spectroscopy has been successfully utilized for the rapid identification of six typical petroleum products such as light straight-run (LSR), naphtha, kerosine, light gas oil (LGO), gasoline, and diesel. The spectral features of each product were reasonably differentiated in the NIR region, and the spectral differences provided enough qualitative spectral information for disc...
Efforts are being made throughout the World to reduce the consumption of liquid petroleum fuels wherever is possible. Biodiesel is recently gaining prominence as a substitute for petroleum based diesel mainly due to environmental considerations and depletion of vital resources like petroleum and coal. According to Indian scenario, the demand for petroleum diesel is increasing day by day hence t...
Road vehicles are a key part of the climate change challenge, representing both an important source of petroleum demand and greenhouse gas (GHG) emissions worldwide. In the United States, light-duty vehicles (LDVs, i.e., cars and light trucks) alone account for 43% of petroleum demand and 23% of GHG emissions, when fuel production is considered [MacKenzie, 2013]. The United States, Europe, Chin...
Petroleum oil is a complex mixture of substances, the majority of which are hydrocarbons; the latter represent an extremely important and heterogeneous group of compounds that find their way into water resources by anthropogenic or natural ways. The majority of toxic hydrocarbon components of petroleum are biodegradable, where bioremediation using microbial species has become an integral proces...
the analyze of the petroleum contract determines that the ownership of the oil and gas filed is one of the very fundamental issues in the petroleum contract not only for the host country in the middle east but also for the petroleum companies. but the analyze of the petroleum contracts from the ownership perspective may show that the hybrid nature of this ownership rights, one from private law ...
