  • Accuracy and precision analysis of chamber-based nitrous oxide gas flux estimates

    Chamber-based estimates of soil-to-atmosphere nitrous oxide (N2O) gas flux tend to underestimate actual emission rates due to inherently nonlinear time series data. In theory, this limitation can be minimized by adjusting measurement conditions to reduce nonlinearity and/or by using flux-calculation (FC) schemes that account for the so-called 'chamber effect.' The current study utilizes gas ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Comprehensive analysis of greenhouse gas emissions in Hungary

    This paper overviews the anthropogenic greenhouse gas emissions in Hungary in the period 1985–95. The emissions have been determined and reported according to the IPCC methodologies. The emissions of greenhouse gases decreased until 1994, basically as a result of the economic recession. Hungary has chosen the yearly average emission level of 1985–87 as the base level. In 1994, greenhouse gas ...

  • `Econometric Analysis on Environmental Sustainability of Gas Based Carbon Economy in 21st Century - - Strategies for Managing Environmental Risks for Sustainable Development of Gas Markets”

    Abstract:On account of growing economies world over and population explosions among Asian / South East Asian Nations, global energy consumptions are expected to increase by 59 - 63 per cent, over a period of 30 years, growing from 382 quadrillion British thermal units (Btu) in 2000 to 607 quadrillion Btu – 620 quadrillion Btu in 2030, representing an average annual growth rate of 2.2 per ...

  • Optimising Compressed Natural Gas filling stations reservoir pressure based on thermodynamic analysis

    A theoretical analysis has been developed to study the effects various parameters on the Compressed Natural Gas (CNG) filling process and the conditions. The analysis is based on first and second laws of thermodynamics, conservation of mass and the AGA8 Equation of State (EOS). Based on AGA8 EOS and thermodynamics relationships, the required properties of natural gas mixtures have been ...

  • 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 ...
