Coal and petroleum are formed from the dead remains of living organisms that is why they are called fossils fuels. Question 5. Give two characteristics of coal. Answer: Coal is hard and is of black in colour. Question 6. Define destructive distillation. Name the residue formed by destructive distillation of coal.
Coal is classified according to: (a) its carbon content. (b) time taken in its formation. (c) layer of earth surface it is found. (d) its non carbon content. (a) its carbon content. 21. In fractional distillation of petroleum, where do the vapours with highest boiling point condense? (a) In the uppermost portion.
5. PRINCIPLE From the operational point of view, fractional distillation is a mass transfer process involving countercurrent diffusion of the components at each equilibrium stage. When a liquid mixture is distilled, the partial condensation of the vapour is allowed to occur in a fractionating column.

Hydrocarbon. ... The residue of coal decomposition that is used in the manufacture of steel is called _____ . coke.
The distillation column process can be carried out in continuous, batch or in semibatch (or semicontinuous) mode. Largescale industrial distillation applications include both batch and continuous fractional, vacuum, azeotropic, extractive, and steam distillation. The most widely used industrial applications of continuous, steadystate ...
There are three major parts of fossil fuels coal, petroleum and natural gas. (iv)The process of heating complex substances in a limited amount of air to produce simple components is called destructive distillation. Coal tar and coal gas are prepared by this method. (v)We can extract petroleum gas by the process of fractional distillation.
It is assumed that readers have previously performed a simple distillation, so in this section are described differences between simple and fractional distillation. Figure : Fractional distillation apparatus. Figure : a) Removal of glass wool plug on a beaded fractionating column, b) Insulating the column with foil, c+d) Condensation on ...
Distillation is an effective and traditional method of desalination. In the petroleum industry, oil stabilization is a form of partial distillation that reduces the vapor pressure of crude oil, thereby making it safe for storage and transport as well as reducing the atmospheric emissions of volatile hydrocarbons.
Relating what happens in the fractionating column to the phase diagram. Suppose you boil a mixture with composition C 1. The vapor over the top of the boiling liquid will be richer in the more volatile component, and will have the composition C 2. That vapor now starts to travel up the fractionating column.

An online condensation system was designed to separate coal tar during cooling process. Traditional method use room temperature ammonia water to cool hot pyrolysis gas by quenching for tar collection, and then follow by dehydration and distillation process for tar separation. This method will cause a lot of wastewater, repetitive energy cost and make system far more complex.
The middle oil (180260°C) fraction was distilled through fractional vacuum distillation using Vigroux column fraction and analyzed using gas chromatographymass spectroscopy (GCMS).
Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.
The uses of fractional distillation are that it enables component separation into different phases and purification of organic compounds. In coal and petroleum class 8 notes, the classification of natural resources, the formation of petroleum and coal and the refining of petroleum along with class 8 Science chapter 5 MCQs are discussed.
The process is similar to oil fractional distillation, but not the same. As of now, this is currently the cleanest coal combustion technique. Plant efficiencies can reach 50% and emissions can be reduced by about 20%, but it is still a long way off from zero emissions.
