  • Removal of Particulate Matter (PM) and NOx from marine exhaust gas by combining electrostatic water-spraying scrubber and emulsion oil

    In this study, experiments were performed with combination using emulsion oil and an electrostatic water spraying scrubber to evaluate effectiveness for simultaneous removal of NOx and Particulate Matter (PM) emissions in marine exhaust gas. The effects of several parameters, such corona power, gas flow rate, on the contaminant removals have been investigated intensively. Total PM removal ...

  • Trelleborg Harbour Marine helps moor vessels safely at LNG terminals

    Trelleborg Harbour Marine helps moor vessels safely at LNG terminalsSafety is the priority at LNG terminals, which are growing in number inline with an increased demand for the fuel. Like many fuels, LNG is potentially hazardous and to help reduce the possibility of an incident during berthing or when a vessel is alongside a jetty, integrated mooring systems are becoming standard specification. ...


  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Can a gas engine use diesel fuel with less pollution?

    Anyone concerned with rising oil prices and pollution from fossil fuel might like to know about a new technology, which addresses both problems. Its application will put an end to the days of sooty smoke seen from accelerating diesel trucks and buses. The ...


  • More to Scrubber Pumps than Meets the Eye

    One component, in particular, needs to be carefully selected to ensure safe and efficient sulphur removal. The time is now Shipowners are having to move fast to change fuel type to distillate fuel or LNG, or to install the exhaust gas cleaning systems (EGC systems) known as scrubbers. They’re reacting to new sulphur emission legislation set to come into force in designated ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • EEA Signals 2015 - Living in a changing climate

    Our climate is changing. Scientific evidence shows that the global average temperature is rising, and rainfall patterns are shifting. It also shows that glaciers, Arctic sea ice and the Greenland ice sheet are melting. The Intergovernmental Panel on Climate Change′s Fifth Assessment Report shows that the warming since the mid-20th century is predominantly due to an increase in ...

  • DESMI Lifts Green Ship Business Case

    New rules call for fresh approach It’s hardly news that the shipping industry is mobilising to meet the demands of wave after wave of new environmental regulations. From the IMO’s ballast water management legislation to EEDI (the Energy Efficiency Design Index for new ships) and SEEMP (Ship Energy Efficiency Management Plan), shipowners need to be ready to drastically cut ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...


  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
