Draw a diagram of bubble plate type fractionating column. When do we require such type of a column for separating two liquids. Explain the principle involved in the separation of components of a mixture of liquids by using fractionating column. What industrial applications does this process have?
The diagram of bubble plate type fractionating column:
The bubble plate type fractionating column can be used for the continuous separation of bulk quantities of liquids, its industrial application are in separation of oil, diesel oil, lubricating oil, etc.
The principle use in the bubble plate type fractionating column is Raoult's law. The fractionating column separates the mixture by cooling the mixed vapours, allowing the vapour to condense, and vaporize again.
