The lime (CaO) reacts with SO2:
2CaO (s) + 2SO2 (g) + O2(g) .........> 2 CaSO4 (s)
So the sulphur dioxide is removed and deposited as calcium sulphate.
how dose limestone remove sulphur in fuel oils
our pyrolysis oil after distillation is 0.045
Coal and oli contain sulphur. When either one burns, it produces sulphur dioxide. The sulphur dioxide gradually turns into sulphur trioxide which mixes with rain and becomes acid rain. It is easy to remove the sulphur in refineries or power plants.
The difference between sulphur dioxide and sulphur trioxide is that there are 2 molecules of oxygen present in sulphur dioxide (SO2) and there are 3 molecules of oxygen are present in sulphur trioxide (SO3).
it sure has something to do with sulphur dioxide
volcanoes usually release sulphur dioxide, after an eruption.
Sulphur dioxide is a reducing agent and is used for bleaching and as a fumigant and food preservative. Large quantities of sulphur dioxide are used in the contact process for the manufacture of sulphuric acid. Sulphur dioxide is used in bleaching wool or straw, and as a disinfectant. Liquid sulphur dioxide has been used in purifying petroleum products
what kind of chemical could be used to remove the acidic sulphur dioxide from flue gases

Coal and oli contain sulphur. When either one burns, it produces sulphur dioxide. The sulphur dioxide gradually turns into sulphur trioxide which mixes with rain and becomes acid rain. It is easy to remove the sulphur in refineries or power plants.
The 'acid' (sulphur dioxide or nitrogen oxides) dissolved in the rain water are acidic. Limestone is alkali. Therefore, the acid in the rain is neutralised by the limstone.
Limestone is used in a power station to neutralise the sulphur dioxide that is emitted. Carbon dioxide and carbon sulphate are both made!
The difference between sulphur dioxide and sulphur trioxide is that there are 2 molecules of oxygen present in sulphur dioxide (SO2) and there are 3 molecules of oxygen are present in sulphur trioxide (SO3).
One reason why limestone is susceptible to chemical weathering because when acid acts on the calcium carbonate in the limestone to form calcium bicarbonate which is dissolved by water, which results in pits and holes found in the limestone. Equations to represent: CaCO3 + H2O + CO2 results in Ca(HCO3)2
The limestone decomposes to quicklime and carbon dioxide, and the quicklime removes acidic impurities (eg SiO2). So basically limestone is to remove impurities
It is a mineral. Sulphur dioxide certainly is not a lipid.

Burning coal (a fossil fuel) releases carbon dioxide and sulphur dioxide.
