Fractional distillation is useful for separating a mixture of substances with minor differences in boiling points. The minor difference means the gap between the boiling points should be less than 25 Kelvin.It is used for the distillation of crude oil in the petroleum industry thereby resulting in the manufacturing of gasoline, lubricating oil, diesel, and plastics.What is Petroleum Refining?Petroleum refining is defined as the process of converting crude oil into useful products. The process involves separation, conversion, and treatment. Crude oil is heated in a furnace so that hydrocarbons can be separated by fractional distillation since there is not much ... Read More

CNG is nothing but Compressed Natural Gas. It is made by compressing natural gas, to less than 1 percent of the volume, it occupies at Standard Atmospheric pressure. Natural gas is mainly composed of Methane.CNG is formed of Natural Gas, as we discussed earlier and the later is formed by the decay of organic matter. Now, when hydrogen is burnt, it releases energy and the only product left as a residue is a water. Since water is clean and not a pollutant, CNG is a clean and safe energy source with a plethora of commercial applications such as electricity generation, ... Read More

Before knowing how to separate crude oil, we must know what actually is crude oil composed of. It is a mixture of comparatively volatile liquid hydrocarbons, though it even contains some nitrogen, sulfur, and oxygen. It occurs underground and can contain natural gas, kept in solution by the pressure at varying depths.SeparationSeparating the mixture of substances in crude oil into fractions by evaporation and condensation is called fractional distillation. There may be light distillates like Naptha and middle distillates like petrol, Tar, oil, and kerosene. In the end, residues such as heavy fuel oil, waxes, grease, or asphalt are obtained.Steps ...
