  • Solid waste management in Patna – analyses of ambient air and ground water pollution

    Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...

  • A positive association between cryptosporidiosis notifications and ambient temperature, Victoria, Australia, 2001–2009

    Increased temperatures provide optimal conditions for pathogen survival, virulence and replication as well as increased opportunities for human–pathogen interaction. This paper examined the relationship between notifications of cryptosporidiosis and temperature in metropolitan and rural areas of Victoria, Australia between 2001 and 2009. A negative binomial regression model was used to analyse ...

  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

  • Energy and exergy analyses of a supercritical power plant

    Energy and exergy efficiencies of a supercritical power plant have been studied in this paper. The effect of ambient weather condition was considered on the condenser pressure. It was shown that high ambient temperature has more adverse effect on the exergy efficiency than the energy efficiency. As ambient temperature increases, the exergy efficiency of the boiler, condenser, heaters and feed ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Exergy analysis of gas turbine – solid oxide fuel cell–based combined cycle power plant

    Fuel cell technology is one of the promising systems for cleaner and competitive alternate power generation systems. When the high temperature fuel cells like solid oxide fuel cell and molten carbon fuel cell are integrated with the gas turbines, the total thermal efficiency of the combined cycle can be obtained greater than 60%. In the present work, thermodynamic analysis of SOFC–GT combined ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Cost allocation in cogeneration power–desalination plant utilising gas/steam combined cycle (GTCC) in Kuwait

    Gas turbine combined cycle (GTCC) plants have high overall thermal efficiency, and are used for large base–load power plants (PPs) to produce electric power (EP) and desalted seawater (DW) at the lowest cost per units of EP and DW. Allocating the cost of each product (EP and DW) is the subject of this paper. Energy and exergy analyses as well as the power loss due to supplying steam to desalting ...

  • The CO2 and SO2 capture capability of two Greek limestones during repeated thermal cycles

    In the present study, two Greek limestones from the Megalopolis and Florina areas were used to capture CO2 and SO2. The regeneration ability and decay of the limestone samples were investigated through sorption-calcination cycles in a thermogravimetric analyser operated at ambient pressure. The effects of the sorption time (3, 8 and 30 min), reaction temperature (750°C and 850°C) and particle ...
