Besides its great potential in controlling water pollution from different sources, waste water treatment system generates significant amount of greenhouse gases. Hence, reducing the emission of greenhouse gases from the wastewater treatment plants is the major concern. The correct understanding and estimation of the greenhouse gases emitted from different points of the plan is essential to tack...

The primary objective of this project is to develop an improved understanding of the factors affecting the toxicology of particulate exhaust emissions. Diesel particulate matter is a known carcinogen, and particulate exhaust emissions from both light-duty and heavy-duty vehicles are toxic. Particulate matter emissions from three light-duty vehicles in five different configurations [a Honda Acco...

In this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of Exhaust Gas Recirculation (EGR) temperature on destruction of the fuel’s availability due to combustion processes in IDI diesel engine cylinder. To serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...

the purpose of this paper is to investigate causality relationship between emission of carbon dioxide, the level of national income and energy consumption in iran consumption of fuel fossil as an input of production or as a final consumption which produces significant amount of pollution such as green house gases in the world. c02 emission is the most important green – house gases which has the...

Compressed biomethane gas (CBG) is an interesting alternative fuel that can be used to solve fossil crisis problems. Nevertheless, it concerned about engine performance and exhaust emission. In additions, CBG produced from agricultural harvesting residues the food industry a good opportunity for utilizing biogas as vehicle fuel. The aims of this research are comparative analysis emission on com...
