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 do you neutralize sulferdioxide gas in power stations?
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.
Is sulfur dioxide a pure substance?
It can be, as long as no other substances are present.
Which has the higher melting point sulfur dioxide or carbon dioxide?
Sulfur dioxide has a higher melting point than carbon dioxide. This is because sulfur dioxide is a smaller molecule with stronger intermolecular forces, making it more difficult to break the bonds in order to melt the substance.
Which substance gives sulphur dioxide when heated in air?
Burning sulfur-containing materials, such as coal, oil, or natural gas, releases sulfur dioxide when heated in air.

These processes help to capture and neutralize sulfur dioxide before it is released into the atmosphere.
What substance can be used to get rid of sulphur dioxide?
Substances like activated carbon, hydrogen peroxide, or sodium hydroxide can be used to remove sulfur dioxide. These substances react with sulfur dioxide to form less harmful compounds or to neutralize its effects.
Is sulfur dioxide a mixture?
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.

This reaction removes sulfur dioxide from the gas stream, reducing its harmful effects on the environment.
Substance that will remove sulfur dioxide?
Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
Is sulfur dioxide a pure substance?
It can be, as long as no other substances are present.
What type of solution is used to remove sulfur dioxide?
One common solution to remove sulfur dioxide is to use a wet scrubber system. This technology involves spraying a solution (such as a lime or limestone slurry) onto the flue gas containing sulfur dioxide to neutralize and remove it. The sulfur dioxide reacts with the solution to form a solid byproduct that can be easily separated.
Which has the higher melting point sulfur dioxide or carbon dioxide?
Sulfur dioxide has a higher melting point than carbon dioxide. This is because sulfur dioxide is a smaller molecule with stronger intermolecular forces, making it more difficult to break the bonds in order to melt the substance.
What is the other substance in the air that combines with sulfur dioxide and nitrogen dioxide to form acid precipitation?
Carbon combines with sulfur and nitrogen in order to form acid precipitation.
Which substance gives sulphur dioxide when heated in air?
Burning sulfur-containing materials, such as coal, oil, or natural gas, releases sulfur dioxide when heated in air.
What substance makes up the haze on Venus?
Sulfur Dioxide & Sulfuric Acid SULPHUR
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.
