Since then, the limits have been progressively tightened, with a new limit of 0.5% coming into force on January 1, which will significantly reduce the amount of sulphur oxides
emanating from ships.
Alfa Laval said that its PureSOx exhaust gas cleaning systems will be installed onboard two luxury cruise liners, where they will remove over 98% of the sulphur oxides
from the ship's exhaust gas.
This new comprehensive set of maps shows Europeans where pollutants are released, on a scale of five km by five km, and includes nitrogen oxides (NOX), sulphur oxides
(SOX), carbon monoxide (CO), ammonia (NH3) and particulate matter (PM10).
It is planned to generate electricity without any emissions of carbon oxide, nitrogen oxides, sulphur oxides
Researchers from MIT say that nitrogen oxides and sulphur oxides
emitted by aircraft at approximately 35,000 feat combine with other gases in the atmosphere to create noxious particulate matter.
The calculator was designed for urban transportation professionals to calculate transportation-related emissions, including greenhouse gases and air contaminants such as carbon, nitrous and sulphur oxides
. The tool calculates both direct and indirect emissions from passenger, commercial and urban transit vehicles.
Five Anglican parishes near the Chevron refinery in North Burnaby, B.C., diocese of New Westminster, are involved in a multi-church coalition opposing Chevron's plan to increase the emission of sulphur oxides
and fine particulates into the atmosphere.
The team's findings flew in the face of previous research on ULSD, which found it reduced the emissions of sulphur oxides
, which cause acid rain, by up to two-thirds.
Stack tests include determining particulate emissions and particle size distribution, sulphur oxides
, nitrogen oxides, volatiles organic compounds, metals, acid gases, air toxics and other pollutants.
The second project, obsAIRve, will provide real time air quality information and alerts on levels of pollutant emissions, primarily sulphur oxides
(SOx), nitrogen oxide (NOx), ozone (O3), carbon monoxide (CO), and particulate matter (PM) delivered directly to the user online, via smart phone platforms and SMS messages.
