What is Sulphur dioxide GCSE?
Fossil fuels naturally contain sulfur compounds. These produce sulfur dioxide, a gas with a sharp, choking smell, when the fuel is burned. When sulfur dioxide dissolves in water droplets in clouds, it makes the rain more acidic than normal.
What is Flue Gas Desulfurization GCSE?
Flue-gas desulfurization involves spraying acidic sulfur dioxide emissions with jets of slaked lime to reduce pollution by neutralising these gases before they leave the factory chimneys. It is also used in treating excess acidity in soils and lakes.
Is wood renewable GCSE?

How long will non-renewable energy last?
Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years. Yet, renewable energy is not popular enough, so emptying our reserves can speed up.
How do you remove sulfur dioxide?
Scale is formed in a closed system wherein an exhaust gas containing sulfur dioxide is treated with an aqueous solution containing an organic acid alkali salt to remove the sulfur dioxide in the form of gypsum from the exhaust gas.
What is global dimming GCSE?
Global dimming: A gradual reduction in the amount of light reaching the Earth’s surface. This can be caused by carbon particulates.
How do you remove SO2 from flue gas?
For the removal of SO2 from flue gas, a wet process using calcium carbonate as an absorbent is most commonly adopted in commercial plants. The wet process shows a high efficiency but needs a large amount of water. SO2 is fixed in the form of calcium sulfate.
