  • 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 ...

  • Energy and exergy analysis of a 16–MW combined cycle district heating system with performance improvements

    Results of an energy and exergy analyses performed on a 16–MW University district heating plant located in the Northeast USA are presented in this paper. Unlike past studies, this paper uses actual data to assess CHP plant performance for all the 8760 h in a year (2011). A system of such complexity, considering the large volume of data available and large variations in system load, has not been ...

  • Calculating Accidental Release Flow Rates From Pressurized Gas Systems

    When determining the consequences of accidental release flow rates from pressurized gas systems, it is important to select the appropriate type of air pollution dispersion model. For released gases which are lighter than or equal to the ambient air density, Gaussian dispersion models as described in Beychok's text1 should be used. For released gases which are heavier than air, a dense gas model ...

  • A novel super-cooled humidification?dehumidification system driven by thermal vapour compression unit for seawater desalination

    The current study presents the concept of a novel seawater desalination system that is configured by a humidification?dehumidification unit based on the vapour-compression process (HDDTVC). The coupled refrigeration unit employs the thermal compression of vapour by a jet-ejector. The new technical idea of proposed desalination system depends mainly upon the creation of a super-cooled temperature ...

  • Results from the latest MPPE Field Trails at NAM and Total installations

    Abstract Within the framework of the Oslo Paris Convention (OSPAR) for the protection of the marine environment of the North East Atlantic, the Danish Environmental Protection Agency (DEPA) was canying out a Project Plan Setting performance standards for aromatic hydrocarbons in produced water'. As part of this plan Akzo Nobel MPP Systems was requested by DEPA to test and evaluate the MPPE ...

  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

  • BREEZE Met Data Facilitates Long Range Dispersion Modeling

    U.S. EPA requires that facilities located within 200 km of Class I areas or others with visibility degradation issues conduct long-range dispersion modeling studies. CALPUFF, an EPA-approved model for long-range transport modeling, is a non-Gaussian, non-steady state, puff model that operates in a Lagrangian framework, unlike the Eulerian approach used by Gaussian dispersion models. The extensive ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • o-Phthalaldehyde Reagent

    Introduction Primary amines form highly fluorescent adducts when reacted with o-Phthalaldehyde (OPA) and a mercaptan under basic conditions. At a pH>9 and ambient temperature, reaction is generally complete within 30 seconds. The products of this reaction, 1-alkyl-2-alkylthio-substituted isoindoles, exhibit optimal excitation at 330 nm and maximal emission at 465 nm. The reagents ...
