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 manufacturers have been forced to ...

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 point and area sources. Emission maps were used in fine ...

Emissions monitoring on ships and an insight into the maritime directive
Shipping continues to grow for the purposes of trade and transportation. This growth is often close to densely populated shores, for example the port of Antwerp in Belgium, Hamburg in Germany and the Bosphorus in Turkey. Air emissions from the marine industry therefore are becoming more important and are increasingly subject to strict targets for reduction of oxides of sulphur (SOx) and nitrogen ...

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 ...

Marine Monitoring of Emissions of Air Pollutants
Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships, a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution. The environmental aspects of ...

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 ...

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 these ...

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 ...

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 in the combustion ...

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 ...

What are the CO2 Emission Levels by Country?
Carbon dioxide emissions are one of the leading causes of climate change. It is generally perceived that to avoid the adverse effects of global warming. The world requires urgently decreasing the amount of carbon dioxide emitted into the atmosphere. In 2018, China was the biggest producer of carbon dioxide on the planet, with approximately 9.2 GT of CO2 emissions. This is around 28 per cent of ...

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 order ...

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 ...

How Refiners Use Monitoring Tools to Support Community Health and Safety
Nothing is more important than the health and safety of our people and our communities—the communities where our employees live, work and go to school. Fenceline monitoring is used at our facilities to aid in the early detection of emissions, including benzene. The data helps us immediately correct problems and nearly all refining facilities quickly return to below action levels after ...

Understanding and Monitoring Hydrocarbons in Water
Untitled Document 1. Introduction Oil contamination continues to be a very hot topic, due largely in part to recent catastrophic events with shipping tankers in open waters. The coastal contamination off Spain, the Valdez in Alaska, accidents off California, refinery spills in Brazil (11), and dozens of other countries have all provided much insight into the damage ...
