How do i reduce nox emissions

It nice and informative sir, I want to know about Ammonia effect in reduction of NOx, because some Industries are using this technique in Boilers and furnaces. It is important to highlight that cylinder lubrication does not neutralise the sulphur in the fuel and reduce SOx emissions from the engine. The purpose of cylinder lubrication besides reducing the abrasive wear is to minimize the corrosive wear from sulphuric acids formed during combustion of heavy fuel oil.

The acids are neutralised by the basic additives incorporated in the lubrication oils the level of basicity is known as TBN. Dear all, I am in search for a topic related to the research on scrubber in ship. Can anyone suggest me one topic. Because I am planning to do a project on this topic.

Reducing SOx Emission SOx or sulphur oxides are formed during combustion process in the engine because of presence of sulphur content in the fuel. Following are the methods and technologies used to reduce sulphur emission from marine engines. Report an Error. Want to share your tips and advice?

Got questions? Heat engines can generate more useful work if they operate at higher temperatures. How do you reduce NOx emissions from diesel engines? Some exhaust gas is cooled and injected back into the combustion chamber. There is less oxygen in the exhaust gas because some has been consumed by previous combustion, so there is not as much to feed the flame. The exhaust gas also has a higher heat capacity than air, so it takes longer to heat up.

Are there any other consequences of using EGR? Yes, there is a downside. As the combustion temperature drops, so does the power, and the fuel economy. How can you remove NOx from exhaust gases? There are various techniques, depending on the applications, although a lot of effort goes into designing burners which reduce NOx emissions in the first place. What are SOx emissions? When fuel is burnt in an engine, any sulphur will be converted into sulphur dioxide SO 2 gas.

This readily dissolves in water to produce an acid, which accounts for the irritation to your respiratory tract if you inhale it. It also affects the ecology. Oil and gas in the ground can contain large quantities of sulphur, which have to be removed in the refinery. Some countries have lax regulations on sulphur content in fuel, with resulting high pollution levels. What is smog?

Fog or haze intensified by smoke or other pollutants. Once at temperature, the reactions are self-sustaining. Huge amounts of hydrogen are made by the 'grey' hydrogen route, which emits CO 2. Anaerobic digesters convert organic matter into a mixture of methane and CO 2.

For an explanation. Methane is everywhere because it is released by decaying organic matter. By signing the MOU, the states committed to develop and adopt regulations that will reduce region-wide NOx emissions by more than , tons per year by through a NOx cap and allowance trading program. The , and NOx emissions from utilities in New England are graphed in a bar chart for comparison. The emissions are also represented geographically on the map link below.

They will only become effective upon adoption of regulations by each state. Through a 2-year effort known as the Ozone Transport Assessment Group OTAG , EPA worked in partnership with the 37 eastern-most states and the District of Columbia, industry representatives, and environmental groups to address ozone transport. OTAG identified and evaluated flexible and cost-effective strategies for reducing long-range transport of ozone and ozone precursors.

By reducing emissions of NOx, the actions directed by these plans will decrease the transport of ozone across state boundaries in the eastern half of the United States. On March 3, , the D. Phase I includes implementation of the major elements upheld by the court whereas Phase II will include implementation of those issues the court remanded back to EPA.

The link below connects you to the proposal which was published in the Federal Register on February 22, 67 FR Based on the emission limit for utility sources, controls such as selective catalytic reduction SCR and selective non-catalytic reduction SNCR will likely be required on a number of units in the OTAG region.
