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.
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 separation of various components of crude oil is one of the very common examples of fractional distillation in the industry. Paraffin wax, diesel, lubricating oil, gasoline, kerosene and naphtha are the substances that crude oil contains. The separation of these components takes place productively with the help of the distillation process.
Destructive distillation of coal This is a process of heating coal in the absence of air. Coal have many elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. When coal is heated in the absence of air, many products are obtained. The main products obtained form coal are coke, coal tar and coal gas. It contains 98% carbon.
The process of evaporating a liquid and condensing the vapors to form a pure substance 2. Used to separate the various compounds of a liquid mixture 3. ... Fractional distillation 3. Volatile 4. Hydrocarbon. ... The residue of coal decomposition that is used in the manufacture of steel is called _____ . coke.
Destructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or is an application of pyrolysis.
