Research ArticleOpen accessIn the abstractEmission and Combustion Characteristics of Si Engine Working Under Gasoline Blended with Ethanol Oxygenated Organic CompoundsDhanapal Balaji, Periyasamy Govindarajan, Jayaraj VenkatesanProblem statement: The objective of this study is to investigate the effect of using unleaded gasoline and additives blends on Spark Ignition engine (SI engine) combustion and exhaust emission. Approach: A four stroke, single cylinder SI engine was used for conducting this study. Exhaust emissions were analysed for Carbon Monoxide (CO), Hydrocarbon (HC) and Oxides of Nitrogen (NOx) and carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractCapturing Biogas: A Means to Reduce Green House Gas Emissions for the Production of Crude Palm OilS. Vijaya, A.N. Ma, Y. M. ChooProblem statement: The Malaysian oil palm industry is an important industry to the nation. In 2009 alone the total export earnings reached RM 49.6 billion. The industry is under constant attack of its performance from the perspective of the environment, especially with regard to its Green House Gas (GHG) Emissions. Being an export orientated industry; this issue has to be … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 14,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuel and Greenhouse Gas Emission Reduction Potentials by Appropriate Fuel Switching and Technology Improvement in the Canadian Electricity Generation SectorFarshid Zabihian, Alan S. FungProblem statement: In recent years, Greenhouse Gas (GHG) emissions and their potential effects on global climate change have been a worldwide concern. According to International Energy Agency (IEA), power generation contributes more than half of the global GHG emissions. Approach: Purpose of this study is to examine GHG emission reduction potentials in the Canadian electricity generation sector through fuel switching … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Excess Oxygen to Mixture on the Gasses Emissions of a Gasoline EngineWaleed MomaniProblem statement: The effects of excess feeding oxygen to the fuel-air mixture on the exhausts gasses emissions concentrations are investigated here. It is known that spark-ignition and diesel engines are considered as major sources of urban air pollution; such pollutants are CO2, CO, HC. Hence, many techniques have been used to decrease such emissions such as: Catalytic converters, oxidizers, traps … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis 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 PDFCite
Research ArticleOpen accessIn the abstractManaging Air in Olympic CitiesQing Wen Tian, Peter BrimblecombeThe 21st century Olympic Agenda aims to align itself with the concept of sustainable development and has driven improved environmental quality in host cities, such as the Green Games in Sydney 2000 and the planned Beijing 2008 Games and in London 2012 as the Low Carbon Games. Air quality has long been a concern of Olympic mega-cities, although the air … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodiesel Fuel Production from Algae as Renewable EnergyA.B.M. Sharif Hossain, Aishah Salleh, Amru Nasrulhaq Boyce et al.Biodiesel is biodegradable, less CO2 and NOx emissions. Continuous use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Algae have emerged as one of the most promising … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 32,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Emissions from Flaring in Kuwait OilfieldsKhaireyah Kh. AL-Hamad, A. R. KhanKuwait is a major oil producing country and its economy directly depends on its export of crude and refined products. Kuwait Oil Company (KOC) is responsible for all exploration and production of crude oil in Kuwait. These activities result in the emission of gaseous pollutants to the atmosphere, particularly from the flaring of undesirable product and excess gases. For environmental … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 8,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Management Systems in Local Authorities: The Case Study of the Cesana Torinese Municipality, a Turin 2006 Olympic SiteSerena Botta, Claudio ComoglioEnvironmental certification according to the ISO 14001 standard and EMAS regulation represents an efficient tool for those organizations who want to continuously improve their environmental performances. Even though first thought up for application to the industrial section, in recent years these schemes have also proved to be valid in organizations with territorial competences, such as local authorities.
