Limestone is used in a power station to neutralise the sulphur dioxide that is emitted. Carbon dioxide and carbon sulphate are both made!

Why are waste gasses from coal-fired power stations passed through calcium carbonate?
In the main the gas released is Sulphur and Carbon monoxide and this is filtered out by the Calcium
What power stations produce CO2?
Coal fired power plants,Petroleum power plants,
Why is wet powdered calcium carbonate sprayed through the waste gasses in a chimney of a coal fired power station?
They do this to decontaminate the emissions (to some extent) that are released into the atmosphere. but answers are fake and so is wikepedia
How do you reduce sulfur dioxide in coal fired power stations?
Using a method called flue gas desulphurisation which involves the addition of a calcium oxide. The calcium oxide basically absorbs the sulphur dioxide on its way out of the flues; economically, useful products are produced such as gypsum which can be used as plaster.
What resources do coal fired power stations use?
The most significant resource that a coal fired power station uses is of course coal. Coal is a non renewable natural resource and mining of coal has significant negative effects. In many cases coal is mined in sensitive grassland and wetland habitats - causing significant water pollution. Power stations also rely on large amounts of freshwater in the cooling towers as part of the power production process.
How and why calcium carbonate is used to remove the acidic gases produced from coal- fired power stations?
Calcium carbonate easily react with acids and a neutralizing reaction occur.

How is Calcium carbonate used to neutralise acid emissions from power stations?
The calcium carbonate reacts with the acid as per any carbonate: Calcium Carbonate + Acid -> Calcium Salt + Water + Carbon Dioxide
Why is it preferable for power stations to use soft water?
it is preferable for power stations to use soft water in their boilers because there is calcium carbonate in it and it does not create scale or scum
How does calcium carbonate reduce harmful emissions from coal-fired power stations?
Coal contains sulphur and when this is burnt(heated) sulphur dioxide is produced, this is a greenhouse gas. To remove this greenhouse gas, this gas is passed a mechanism like a shower that is able to dissolve it and make it an acid. Then this acid sulphur is neutralized with calcium carbonate to form calcium sulphate, water and carbon dioxided
Which pollutants can be removed from the chimney gases of factories and power stations by treatment with calcium carbonate?
Sulphur dioxide
What kind of steam engines are used in power stations?
Coal fired steam driven power stations are still in use
What power stations produce CO2?
Coal fired power plants,Petroleum power plants,

Why is South Africa investing on gas-fired power stations?
South Africa is investing on gas-fired power stations because gas is a cheaper natural resource, it is efficient and does not produce a lot of pollution when it is burnt to generate electricity.

Calcium carbonates be used to remove acidic gases from power stations?
it sure has something to do with sulphur dioxide
