  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • 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 ...

  • Air pollution from ships

    Emissions from shipping contribute significantly to the concentrations and fallout of harmful air pollutants in Europe. There are however technical means by which these pollutants could be cut by as much as 80-90 per cent, and very cost-effectively compared with what would have to be done to achieve similar results by taking further measures on land-based sources. Such reductions are needed for ...

  • Experimental method for marine engine’s emissions analysis

    Abstract The world is considering various solutions to reduce exhaust emissions, the use of alternative fuels and the development of more efficient marine engines. IMO the company gave guidance for future borders of individual exhaust components, taking into account a variety of applications and conditions for the operation of marine engines. Engine ...

  • Best practices in marine sample preparation with the Precellys® range

    Green house gas emissions might lead to a "collapse" of marine species and thus of the food chain. 10 to 12% of the species might disappear if the temperature increases by 2°C compared to thepre-industrialera. Advances in  research regarding the behavior of the marine world using protein markers, genetics and direct observations allow researchers to better apprehend the biodiversity and ...

  • Modelling emission, concentration and deposition of sodium for Poland

    The aim of this paper was to calculate natural and anthropogenic emission of Na+ and to estimate, with the FRAME model, annual air concentration and deposition of Na+ for the domain covering Poland. Calculations of natural emissions included marine emission and wind blown dust from land. Anthropogenic emission was calculated for both ...

  • Modelling the influence of dimethyl sulphide on aerosol production in the marine boundary layer

    It has been postulated that dimethyl sulphide (DMS) emissions from the oceans can produce new condensation nuclei and eventually cloud condensation nuclei. Thus, DMS may have a significant influence on the Earth's radiation budget. A study of this postulate has been conducted for marine boundary layer conditions using a newly developed chemistry–aerosol–cloud (CAC) modelling system. The CAC ...

  • Emission reduction methods and split fuel injection in a marine four-stroke engine

    Abstract The new emission legislation for sea-going vessels issued by the International Maritime Organization (IMO) requires drastic reduction in exhaust gas nitrogen oxides (NOX), and the combination of different primary methods can be an interesting solution without increasing remarkably the machinery. In this paper, the Miller cycle and the dilution with exhaust gas ...

  • CO2 Emissions From Fuel Combustion Highlights 2014

    In the lead-up to the UN climate negotiations in Lima, the latest information on the level and growth of CO2 emissions, their source and geographic distribution will be essential to lay the foundation for a global agreement. To provide input to and support for the UN process, the IEA is making available for free download the "Highlights" version of  ...

  • Biological monitoring system, iTOXcontrol, continues in Scarlino - Case Study

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

  • Mater-bi starch-based materials : present situation and future perspectives

    The environmental impact related to the emissions of gases with green-house effect and the management of solid waste disposal with regard to the decreasing availability of landfills, the litter problem and the pollution of the marine environment became very urgent in the last decade. An obliged approach to solve the problem is: the valorisation of waste as a resource through its separation into ...

  • Sustainable desalination: environmental approaches

    Abstract The environmental issues of possible concern during construction and operation of desalination plants (mainly large-scale facilities) include impacts that are common to many coastal development projects (e.g. land use and aesthetic impacts), as well as specific impacts associated with the elements of the desalination system and auxiliary infrastructure. In the latter category ...

  • MARPOL ANNEX VI Compliance Using a Portable Emissions Analyzer - Case study

    Marine vessels can emit air pollution such as CO, CO2, NOx (NO+NO2), and SO2 from their diesel engines and onboard incinerators. MARPOL Annex VI and the technical code for control of emissions of nitrogen oxides (NOx Technical Code) issued by IMO are internationally recognized regulations for the prevention of air pollution and emissions from marine ...

  • Prevent biofouling and reduce fuel costs in sea chests, hulls and cooling basins

    Biofouling growth increases the drag on a hull which results in a ship that uses up to 40% more fuel and correspondingly produces 40% more CO2 emissions. The marine industry globally spends billions of dollars in addressing fouling, using a variety of protection methods such as coatings. LG Sonic, a Dutch algae and biofouling control solutions provider, has introduced an Industrial Line which ...

  • Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)

    The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid  waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in ...

  • The impact of international shipping on European air quality and climate forcing

    Due to its dependence on fossil fuel combustion and the fact that it is one of the least regulated anthropogenic emission sources, emissions from the marine transport sector contribute significantly to air pollution and climate change. The main objective of this report is to provide a comprehensive review of recent literature and reports, taking into account expert knowledge, on the maritime ...

  • Cobalt and its compounds

    Abstract Cobalt is a compound that occurs in nature. It occurs in many different chemical forms. Pure cobalt is a steel-gray, shiny, hard metal. Cobalt used in industry is imported or obtained by recycling scrap metal that contains cobalt.
