  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...

  • Meeting emission control through improved actuation

    Introduction Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren't designed using the latest materials and technologies. New technologies can ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Controlling Fugitive Emissions, Part 2: Permanent Total Enclosure

    Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an ...

  • Zero Emissions through State-of-the-Art SF6 Gas Handling

    Introduction This article gives an overview on current international regulations, state-of-the-art SF6 gas handling equipment and SF6 re-use based on DILO’s “zero emission” philosophy. Pros and cons SF6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability and has been successfully used ...

  • Trends and projections in the EU ETS in 2017

    About this report This 2017 report of the European Environment Agency (EEA) provides an analysis of past, present and future emissions trends under the European Union (EU) Emissions Trading System (ETS), based on the latest data and information available from the European Commission (July 2017 data on verified emissions and compliance by operators under the EU ETS for the years up ...

  • Life cycle assessment of sludge management with phosphorus utilisation and improved hygienisation in Sweden

    To provide input to sewage sludge management strategies that address expected new regulations in terms of hygienisation and phosphorus recovery in Sweden, an environmental life cycle assessment (LCA) was made. The LCA identified environmental hot spots for methods that may permit sludge or phosphorus from sludge to be applied on agricultural land. In particular, thermophilic digestion, ...

    Over the last decades, considerable progress has been made in the understanding of the sulfur cycle in sewer systems. In spite of a wealth of experimental and field studies that have addressed the release of hydrogen sulfide from free surface flows in gravity sewers and the corresponding air-water mass transfer, little is known about hydrogen sulfide emission under highly turbulent conditions ...

  • Waste materials are an underused resource the construction of Europe`s roads

    Recycled waste material could play a major role in the construction of roads in Europe, bringing both environmental and economic benefits. A new study proposes a scenario where 50% of the asphalt for Europe's roads consists of recycled materials, leading to significant reductions in costs, energy use and greenhouse gas emissions. According to the European Waste Framework Directive, there is a ...

  • Dredging Up Power

    Caterpillar Marine was selected to power three 3500 m³ trailing suction hopper dredgers for the Jan De Nul Group with Cat 3500E IMO III and EPA Tier 4 certified engines. Cat said the 3500E incorporates selective catalyst reduction (SCR) after-treatment technology with closed-loop NOx sensing and application optimized performance for minimized owning and operating costs. “Embedded ...

  • Glass and UV-Passing Acrylic Lens in UV Light Applications

    Glass and UV-passing acrylic lenses play an important role in ultraviolet (UV) lighting. Both are applied to control the transmission of specific wavelengths from the fixture to the target area. When used for windows, the panels offer protection from harmful UV bands. Below highlights the advantages of the materials and their applications in UV light mitigation. Glass and UV ...

  • How California’s greenhouse gas laws can better serve disadvantaged communities

    Environmental justice advocates are working to ensure the state’s efforts to combat climate change benefit everyone — and the lessons can be applied nationwide. It was a time of year that should have been perfect. Warming temperatures marked Southern California’s gentle return to spring. The grass had shifted from drab to glowing green. The sky, which can be pale and ...

  • Use of process analyzers in cement plants solutions from Siemens – Case Study

    Cement is a hydraulic binding agent to produce concrete. Due in part to the fast growth of the Asian economies, world consumption of cement is currently growing at an annual rate of 8%. Therefore, cement production is expanding and, at the same time, production processes need to be optimized to ensure maximum efficiency. In this context, process analytics plays an important role: It determines ...

  • Environmental monitoring solutions - Total solution for measuring benzene in gasoline – Case Study

    EPA rule 40 CFR Parts 59, 80, 85, 86 (Control of Hazardous Air Pollutants From Mobile Sources) is about to reduce allowable emissions of benzene and other mobile source air toxics. It originally went into effect on April 27, 2007, with a recent Final Release on October 8, 2008. On January 1, 2011, the rule limits the benzene content of reformulated gasoline (RFG) and conventional gasoline (CG) ...

  • Water management solutions minimize flood damage

    Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

  • Climate change is more than a tech problem, so we need more than a tech solution

    At the COP 21 climate convention in Paris at the end of 2015, leaders from 194 nations agreed to pursue actions that will cut greenhouse gas emissions enough to keep global warming within 1.5 °C (2.7 °F) above pre-industrial conditions. Meeting this goal will avoid continued and increasing harm to people and ecosystems around the world caused by a changing climate, and it is also a great ...
