Research ArticleOpen accessEvery word in the titleUsing a Simulation Tool to Model the Ground Level Concentrations of Green House Gases Emitted by Flaring in Petroleum Production in Kuwait OilfieldsKhaireyah Kh. AL-Hamad, V. Nassehi, A.R. KhanAir pollution and its effects on the ecosystem has been a source of concern for many environmental pollution organizations in the world. In particular climatologists who are not directly involved in petroleum industry sometimes express concerns about the environmental impacts of gas emissions from flaring at well heads. For environmental and resource conservation reasons, flaring should always be minimized as … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,667 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSolid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanWaste management became focus of attention of many researchers and scientists in the last half century due to its vital importance. Waste management covered waste source reduction in general, by recycling, reusing, composting, incineration with or without energy recovery, fuel production and land filling. A common approach of waste management models were for specific problems with a limited scope (like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,939 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleEnvironmental Degradation in the Niger Delta Area Due to Petroleum Exploration: Are we Combating the Problems?Agnes Edet Asuquo Offiong, Onnogen Usang Nkanu, Etim Nkanu Efut, Uba James UbaNative settlements where oil and gas are produced in Africa are frequently challenged by environmental pollution. This challenge usually causes conflicts within the exploitation arena. Little effort is deceptively portrayed by the government and private organizations to ameliorate the impact of pollution on environmental media and human health risks due to exposure. A critical attribute of these worries has been … …American Journal of Environmental Sciences, Vol. 14, Issue 6 · 27 Dec 2018 · 8,332 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssisted History Matching for Petroleum Reservoirs in the Social Computing EraMichel Cancelliere, Dario Viberti, Francesca VergaThe exploitation strategy of hydrocarbon reservoirs can be technically and economically optimized only if a reliable numerical model of the reservoir under investigation is available to predict the system response for different production scenarios. A numerical model can be reasonably trustworthy after calibration only, which means the model has at least proved its ability to reproduce the historical behavior of … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,083 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiosurfactan Production by Bacillus sp. Isolated from Petroleum Contaminated Soils of Sirri IslandM. Ghayyomi Jazeh, F. Forghani, Deog-Hwan OhProblem statement: Biosurfactants are active surface components produced by some bacteria and fungi. These molecules reduce surface and interfacial tension in aqueous solutions and hydrocarbon mixtures. The most important application of biosurfactants is in oil industry to enhance oil quality and facilitate oil extraction. The aim of this study was to isolate biosurfactant producing bacteria and optimize the conditions like … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 13 Jan 2012 · 8,552 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Contribution of Lube Additives to the Life Cycle Impacts of Fully Formulated Petroleum-Based LubricantsGiorgia Girotti, Andrea Raimondi, Gian Andrea Blengini, Debora FinoProblem statement: Previous applications of the Life Cycle Assessment (LCA) methodology to lubricants are not sufficiently detailed and comprehensive for R and D purposes and there are no LCAs of lube additives and fully formulated lubricants. The aim of this study is to integrate and expand previous LCAs of lubricants and to investigate on the contribution of lube additives to … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 9,359 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Three Bacteria Consortium for the Bioremediation of Crude Petroleum-oil in Contaminated WaterAbdualdaim Mohammed Mukred, Aidil Abd Hamid, Ainon Hamzah, Wan Mohtar Wan YusoffWe have to developed active microbial consortium that could be of higher degradation of crude oil contaminated groundwater, wastewater aeration pond and biopond at the oil refinery Terengganu Malaysia. Among four isolates that showed good growth only three different isolates (Acinetobacter faecalis WD2, Staphylococcus. sp DD3 and Neisseria elongate TDA4.) were selected based on the growth ability and degradation. Significant … …OnLine Journal of Biological Sciences, Vol. 8, Issue 4 · 31 Dec 2008 · 10,133 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRutting and Fatigue Cracking Susceptibility of Polystyrene Modified AsphaltNazim Mohamed, Demitri Ramlochan, Rean MaharajThe absence of studies investigating the influence of waste Polystyrene (PS) on the performance characteristics of rutting resistance and fatigue cracking resistance of the indigenous asphaltic materials Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB), has hindered the possible use of PS as a performance enhancer as observed with other asphalts from different sources thus also developing a sustainable … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 1 Jun 2017 · 7,666 accessesView PDFCite
