Distilation Column

Distillation column is one of the unit operations, Distillation columns are widely used in chemical process industries where large quantities of liquids have to be distilled.[3][4][5] Such industries are petroleum processing, petrochemical production, natural gas processing, coal tar processing, brewing, liquefied air separation, and hydrocarbon solvents production.
Distillation finds its widest application in petroleum refineries. In such refineries, the crude oil feedstock is a complex, multicomponent mixture that must be separated.
Yields of pure chemical compounds are generally not expected, however, yields of groups of compounds within a relatively small range of boiling. points, also called fractions, are expected. This process is the origin of the name fractional distillation or fractionation.
