Sulfur dioxide gas in power stations can be neutralized by using a process called flue-gas desulfurization (FGD), which involves reacting the gas with an alkaline solution, commonly limestone slurry, to form calcium sulfite or sulfate. This reaction removes sulfur dioxide from the gas stream, reducing its harmful effects on the environment.

Which substance is used to neutralize sulfur dioxide in fue gases from power stations?
Limestone (calcium carbonate) is commonly used to neutralize sulfur dioxide in flue gases from power stations through a process called flue gas desulfurization (FGD). When sulfur dioxide reacts with limestone, it forms calcium sulfite, which can then be further oxidized to form gypsum (calcium sulfate), a less harmful solid waste product.
Are nuclear power stations more efficient than coal power stations?
Yes, nuclear power stations are generally more efficient than coal power stations, as they can generate more electricity with the same amount of fuel. Nuclear power produces less waste and greenhouse gas emissions compared to coal power.
How is sulfur dioxide removed from coal fired power stations?
Sulfur dioxide in coal-fired power stations is typically removed using a process called flue gas desulfurization (FGD). This can be done through methods such as scrubbing with a limestone slurry or using specialized equipment like dry sorbent injection systems. These processes help to capture and neutralize sulfur dioxide before it is released into the atmosphere.
What power stations produce CO2?
Most power stations that burn fossil fuels such as coal, oil, and natural gas produce CO2 as a byproduct of combustion. These fossil fuel power stations are major contributors to CO2 emissions and climate change.
How is limestone used in power station?
Limestone is used in power stations to remove sulfur dioxide gas emissions from the burning of coal. This process, known as flue gas desulfurization, involves spraying a slurry of limestone in water into the flue gas to neutralize and capture sulfur dioxide, reducing air pollution.
Where does sulferdioxide come from?
comes from the burning of coal gas, oil..

What percentage of power stations in the UK are gas powered?
39%
How do gas power stations work?
the power station works in different processes of electricity
What are some different configurations of power stations?
Power Stations have the same principle of working and that is the use of combined cycles for several heating systems. The power stations can use a gas combined cycle or a solar cycle.
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.
Which type of fossil fuel power station has the shortest start-up time?
Natural gas power stations typically have the shortest start-up time among fossil fuel power stations. This is because natural gas power plants can ramp up to full capacity quickly compared to coal or nuclear power plants.
Are nuclear power stations more efficient than coal power stations?
Yes, nuclear power stations are generally more efficient than coal power stations, as they can generate more electricity with the same amount of fuel. Nuclear power produces less waste and greenhouse gas emissions compared to coal power.

How do people in Antarctica get their source of power?
Research stations generate their own power, usually from gas-generated motors.
What are the problems of power stations?
The stations letting CO2 gas out to the atmosphere to act as a blanket or a green house so this makes our earth warmer and this stations damage our plants and animals.
Is it true that coal and natural gas are the main fossil fuels used in nuclear power stations?
Fossil fuels are not used in nuclear power stations. Nuclear fuel is used (uranium)
