Research ArticleOpen accessIntegrating Renewable and Nonrenewable Energies in Power Plant PlanningHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiProblem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,804 accessesView PDF Cite

Research ArticleOpen accessHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,592 accessesView PDF Cite

Research ArticleOpen accessModeling of Activated Sludge Floc CharacteristicsIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem Statement: The activated sludge system needs to improve the operational performance and to achieve more effective control. To realize this, a better quantitative understanding of the biofloc characteristics is required. The objectives of this study were to: (i) Study the biofloc characteristics from kinetics-mass transfer interaction point of view by quantification of the weight of the aerobic portion of … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,422 accessesView PDF Cite

Research ArticleOpen accessAnalysis and Optimization of Carbon Dioxide Emission Mitigation Options in the Cement IndustryMohammed Ba-Shammakh, Hernane Caruso, Ali Elkamel et al.The cement industry is responsible for approximately 5% of global anthropogenic carbon dioxide emissions emitting nearly 900 kg of CO2 for every 1000 kg of cement produced. Effective control strategies to mitigate these emissions are discussed and a mathematical programming model able to suggest the best cost effective strategy is outlined. Control costs consisting of operating and investment costs along … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,387 accessesView PDF Cite

Research ArticleOpen accessOptimal Production Planning of Electricity from Coal-Fired Power Plant Networks under Environmental ConsiderationsHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiIn this study, electricity production from a network of coal power plants and under environmental constraints is considered. Several pollutants are incorporated into the decision planning process including nitrogen oxides (NOx), sulfur oxides (SOx) and mercury (Hg). A Nonconvex Mixed Integer Nonlinear Programming (MINLP) model was first developed to assist in the evaluation process. An exact linearization of the nonconvex … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 7,070 accessesView PDF Cite
