  • EU fuel quality monitoring — 2014

    Each year, under the requirements of the European Union (EU) Fuel Quality Directive (FQD) (1), EU Member States must report various types of information relating to the quality of petrol and diesel fuels sold in their territories. More specifically, Member States must sample fuels each year and analyse their technical characteristics to ensure that they are consistent with the requirements of the ...

  • Geochemical control processes and potential sediment toxicity in a mine‐impacted lake

    Geochemical parameters and major ion concentrations from sediments of a freshwater lake in the town of Åtvidaberg, south‐eastern, Sweden, were used to identify the geochemical processes that control the water chemistry. The lake sediments are anoxic, characterized by reduced sulphur and sulphidic minerals. The hypothesis tested is that in sulphidic‐anaerobic contaminated sediments, the ...

  • Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations

    Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...

  • Seabank Power Station, Great Britain

    The challenge was big: For the gas and steam power station in Bristol, Great Britain, that went on stream at the end of the year 2000, the waste water of a near-by sewage plant had to be used as cooling water. Siemens PLC, the designer of the 750 megawatt Seabank Power Station, engaged Grundfos Alldos for this complex and extensive task in chemical engineering. Start of the gigantic project was ...


  • Beyond Zero: Integrating behaviour-based safety at ORYX GTL - Case Study

    Situation Located in Ras Laffan Industrial City, the ORYX GTL plant is Qatar's first commercial producer to process natural gas into low-sulphur and environmentally friendly diesel, naphtha, and LPG. 32,000 barrels of diesel and 8,000 barrels of naphtha are produced every day at the site. Using a gas-to-liquids refining process, ORYX GTL is able to produce fuel low in sulphur and aromatic ...

  • CHP efficiency for biogas

    Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to ...

  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...


  • Removal of Lead from Gasoline

    On 12th March 1997, the European Commission adopted a proposal from the Environment Commissioner Ritt Bjerregaard on a European Union strategy to combat acidification. The strategy will, by 2010, reduce significantly the extent of the areas in the European Union where the tolerance of sensitive ecosystems to acidity is exceeded. Main elements of the strategy include establishment of national ...

  • Chromium detection in water and soil...

    What is chromium? Chromium is a metal that is widely distributed in the earth’s crust (soil and rocks), air and water. Naturally occurring chromium occurs mainly in the chromium (III) form as chromite ore, which contains oxygen, chromium (III) and other metals such as iron. Chromium (VI) compounds are produced commercially from chromite ore for a wide variety of uses. ...

  • EMEP/EEA air pollutant emission inventory guidebook 2016

    1 Guidebook Introduction 1.1 Introduction The joint EMEP (1)/EEA Air Pollutant Emission Inventory Guidebook (the 'Guidebook'), following the 'Guidelines for Reporting Emissions and Projections Data' under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP) (2), provides concise guidance on how ...

  • A matter of refinement

    With over 1.2-billion litres of finished lubricants sold in Canada each year, the environmental importance of managing the associated waste stream is significant. Used oil, if not handled properly, can result in contamination and major environmental damage. In fact, according to Alice Chung, regional manager in charge of Newalta's North Vancouver facility (one of only two used oil re-refineries ...

  • Generation using gas-fuelled engines in South Africa – an overview

    Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
