The lime (CaO) reacts with SO2:

2CaO (s) + 2SO2 (g) + O2(g) .........> 2 CaSO4 (s)

So the sulphur dioxide is removed and deposited as calcium sulphate.

How can sulphur dioxide be removed from flue gas by wet scrubbing?

Sulphur dioxide can be removed from flue gas by wet scrubbing using a scrubbing solution such as a slurry of limestone in water. The sulphur dioxide reacts with the alkaline solution to form calcium sulfite or sulfate, which can then be separated from the gas stream. The scrubbed gas is then released into the atmosphere with reduced sulphur dioxide levels.


Who were the first people to remove sulphur dioxide from power stations?

Why arnt limestone lakes affected by acid rain?

The 'acid' (sulphur dioxide or nitrogen oxides) dissolved in the rain water are acidic. Limestone is alkali. Therefore, the acid in the rain is neutralised by the limstone.


Limestone weathering does not remove carbon di oxide from the atomospher.why not?

Limestone weathering does not remove carbon dioxide from the atmosphere because the carbon dioxide released during the weathering process is eventually reabsorbed by other chemical reactions, such as the formation of bicarbonate ions in water. The overall effect of limestone weathering on atmospheric carbon dioxide levels is neutral.


Which chemical could be used to remove the acidic sulphur dioxide from flue gases?

Lime (calcium oxide or calcium hydroxide) is commonly used to remove acidic sulfur dioxide from flue gases. The sulfur dioxide reacts with lime to form calcium sulfite or calcium sulfate, which can then be removed from the gas stream.


Is sulphur dioxide a hydrocarbonprotienvitamen mineral or lipid?

It is a mineral. Sulphur dioxide certainly is not a lipid.


What is sulphur precipitator?

A sulphur precipitator is a device used to remove sulphur dioxide from industrial exhaust gases. By passing the gases through the precipitator, sulphur dioxide is converted into a solid particulate form that can be easily collected and disposed of. This helps reduce air pollution and its negative effects on the environment and human health.


Which energy sources produce carbon dioxide and sulphur dioxide?

Burning coal (a fossil fuel) releases carbon dioxide and sulphur dioxide.


Is sulphur dioxide an acid base or neutral?

Sulphur dioxide is an acidic compound. When dissolved in water, sulphur dioxide produces sulphurous acid, which gives it acidic properties.


What do you add to sulphur to make sulphur dioxide?

You add oxygen to sulfur to make sulfur dioxide.


Why is sulphur dioxide produced in petrol engines?

Sulphur dioxide is produced in petrol engines due to the combustion of sulphur-containing compounds present in the fuel. When these compounds are burned, they react with oxygen to form sulphur dioxide as a byproduct, which is then emitted through the exhaust. Reducing the sulphur content in petrol can help minimize the production of sulphur dioxide emissions.


How is the release of sulphur dioxide prevented in UK power stations?

Sulphur dioxide release in UK power stations is prevented through the use of desulfurization technologies, such as flue gas desulfurization systems that remove sulphur compounds before they are emitted into the atmosphere. Additionally, the UK has regulations in place that set limits on sulphur dioxide emissions from power stations, which are enforced through monitoring and compliance protocols.
