Research ArticleOpen accessIn the abstractSolid 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
Research ArticleOpen accessIn the abstractRole of Evaporation in Degrading the "Oil Lakes"Al Rashed Ahamad, Colin BarkerProblem statement: Oil Spills are degraded by aerobic bacteria, water washing, evaporation and oxidation. In the absence of water the first two of these processes cannot operate. This is the situation in the low rainfall environment of the Kuwaiti desert where oil lakes still persist 20 years after the initial spills. The oils contain longer chain n-alkanes but have lost … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,747 accessesView PDFCite
