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.
What else can I help you with?
Why do you need to test the levels of sulphur dioxide in flue gas?
Testing the levels of sulphur dioxide in flue gas is important because it is a harmful pollutant that can lead to acid rain, respiratory issues, and environmental damage. Monitoring these levels helps to ensure compliance with regulations, assess environmental impact, and protect human health.
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.
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.
How is sulfur removed in power stations?
Sulfur can be removed from emissions at power stations through a process called flue gas desulfurization, which involves injecting a substance like limestone or lime into the exhaust gases. This reacts with the sulfur dioxide to form compounds like calcium sulfite or sulfate, which are then removed from the gases before being released into the atmosphere. Another method is called dry sorbent injection, where a powdered sorbent such as calcium hydroxide is injected into the flue gas to react with sulfur dioxide.
What happens when an oxide reacts with sulphur dioxide?
When an oxide reacts with sulfur dioxide, it can form a sulfate. The sulfur dioxide can oxidize the metal in the oxide, resulting in the formation of a metal sulfate compound. This reaction is often used in industrial processes to remove sulfur dioxide emissions from flue gases.
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.
What does a flue gas desulphurisation plant do?
A flue gas Desulphurisation (FGD) plant removes Sulphur Dioxide from the flue gas before it is released into the atmosphere and hence reduces our impact on the environment.
Why do you need to test the levels of sulphur dioxide in flue gas?
Testing the levels of sulphur dioxide in flue gas is important because it is a harmful pollutant that can lead to acid rain, respiratory issues, and environmental damage. Monitoring these levels helps to ensure compliance with regulations, assess environmental impact, and protect human health.

What can be done to reduce the amount of sulphur dioxide produced?
The most common process is 2 steps:Run the flue gasses through a catalyst with excess oxygen to convert the SO2 to SO3.Bubble that through a tank of crushed limestone and water slurry to produce gypsum CaSO4.Another process is also 2 steps:Run the flue gasses through a catalyst with excess oxygen to convert the SO2 to SO3.Bubble that through a tank of water to produce sulfuric acid H2SO4.In either process, the gypsum or sulfuric acid can be sold.
What happens when an oxide reacts with sulphur dioxide?
When an oxide reacts with sulfur dioxide, it can form a sulfate. The sulfur dioxide can oxidize the metal in the oxide, resulting in the formation of a metal sulfate compound. This reaction is often used in industrial processes to remove sulfur dioxide emissions from flue gases.
How is sulfur dioxide removed from coal in power station emissions?
Sulfur dioxide is typically removed from coal emissions using a process called flue gas desulfurization (FGD), which utilizes either wet scrubbers or dry scrubbers. Wet scrubbers use a liquid solution to absorb sulfur dioxide from the flue gas, while dry scrubbers typically use a powdered sorbent. These methods help to reduce sulfur dioxide emissions and comply with environmental regulations.
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.
How can you reduce the amount of sulfur dioxide released?
Some types of coal contain sulphur, and when burned, release sulphur dioxide; this is the major source of sulphur dioxide emissions. There are ways to scrub pollutants out of the smoke emitted by coal-burning power plants, however, I personally think that it makes more sense to stop burning coal and switch to other methods of power generation.
