Why is sulphur removed from petrol before it is used as a fuel for motor vehicles?
Sulphur is removed from petrol in some countries because burning petroleum releases sulphur dioxide. This mixes with water vapour and rain in the atmosphere to cause acid rain.
What happen when petrol is in taken?
stupids i asked the question, then why should i answer it
What is sulfurs ionization energy?
The ionization energy of sulfur is the energy required to remove an electron from a sulfur atom in its gaseous state. The first ionization energy of sulfur is about 10.4 electron volts (eV), while subsequent ionization energies increase as more electrons are removed.
What are the products formed when fuel such as petrol burns completely?
When petrol burns completely, it reacts with oxygen to produce carbon dioxide, water vapor, and heat energy. This combustion process is essential for powering engines and generating energy for various applications.
How is petrol separated from the mixture of hydrocarbons?
Petrol is obtained from crude oil by fractional distillation and subsequent mixing of some of the fractions to obtain the desired properties. There are seasonal differences in petrol to facilitate vehicle operation under different climactic conditions. Some of the fractions for the petrol may be obtained by "cracking" higher molecular weight fractions to lower molecular weights. Some impurities, like sulfur, and some unsaturation of the fraction may be removed by treatment with hydrogen which replaces the impurity on the hydrocarbon molecule or adds hydrogen to the molecule to make it more stable. Some of the fractions may be treated to rearrange some of the molecules to make a more desireable product. It is a complex process that is highly dependant on the crude source, desired products, time of year, and the configuration of the refinery. From the same crude may come: fractions for making plastics, rubber, heating oil, diesel and gasoline fuels, lpg fuel, lubricants, solvents, petroleum coke, elemental sulfur, asphalt, bunker fuel oil, etc.
Why does sulfur have to be removed out of petrol and diesel before they are burnt?
Sulfur in petrol and diesel can form sulfur dioxide when burned, which contributes to air pollution and causes respiratory problems. Removing sulfur reduces harmful emissions and helps protect public health and the environment.
Why is sulfur dioxide produced in a petrol engine?
Sulfur dioxide is produced in a petrol engine when the fuel being burned contains sulfur impurities. As the fuel combusts, sulfur in the fuel reacts with oxygen in the air to form sulfur dioxide, which is then emitted as a pollutant in the exhaust gases of the engine.
Why should the sulfur dioxide be removed from the waste gases?
Sulfur dioxide should be removed from waste gases because it is a major air pollutant that can contribute to acid rain, respiratory problems, and environmental damage. By removing sulfur dioxide, we can reduce these negative effects and improve air quality.
Why should petrol be saved?
Petrol should be saved. It is a limited resource.
What is removed when putting out a forest fire?
fire is removed and small pieces of fire petrol are covered with the fire extinguisher.
What happens if petrol burns with small amounts of sulfur?
Burning petrol with small amounts of sulfur can release sulfur dioxide gas into the air. This can contribute to air pollution and cause respiratory issues for humans, as well as harm the environment by contributing to acid rain formation. It can also lead to the degradation of engine components over time.
How sulfur is removed from fossil fuel?
Sulfur is removed from fossil fuels through a process called desulfurization. This can involve methods like hydrodesulfurization, which uses hydrogen to convert sulfur compounds into hydrogen sulfide, which can then be captured and removed. Alternatively, flue gas desulfurization can be used to remove sulfur dioxide from the emissions produced when fossil fuels are burned.
How can sulfur dioxide be removed using calcium oxide?
Sulfur dioxide can be removed by scrubbing the gas with a solution of calcium oxide. The calcium oxide reacts with sulfur dioxide to form calcium sulfite, which can then be further oxidized to calcium sulfate. This process helps to reduce the concentration of sulfur dioxide in the gas stream.
Why is sulfur removed from the petroleum products?
Sulfur is removed from petroleum products to reduce air pollution when these products are burned. Sulfur dioxide emissions contribute to acid rain and other negative environmental impacts. Removing sulfur also helps prevent damage to vehicles and machinery that can be caused by sulfur-containing compounds.
Was lead removed from petrol because it was dangerous or it was cheaper to produce with out it?
dangerous.....
Should you drink petrol?
No, you should not.
Why should you conserve petrol?
So that in the future, petrol will be there for us to use.
