Fractional Distillation Column Gcse

Fractional distillation column and possible products.

Fractional distillation column gcse. Further chemical reactions rates and equilibrium calculations and organic chemistry. Hence the industrial fractionating column is acting as a highly specialised condenser of the crude oil vapour. Fractional distillation differs from simple distillation because the fractionating column naturally separates compounds based on their boiling points. Fractional distillation of crude oil gcse.

Several columns are shown in figure 5 39. The molecules that condense at the bottom of the column where it is hottest are the heaviest molecules as these have very high boiling points. To separate this mixture the air must be cooled to 200 o c which turns it into a. The choice of what fractionating column to use for which application depends in part on availability and the task at hand.

Fractional distillation separates a mixture into a number of different parts called fractions. Air is a mixture of nitrogen oxygen carbon dioxide and some other gases. Fractional distillation can be used to separate a mixture of compounds with different boiling points such as crude oil or air. Crude oil is vaporised and added to the fractionating column.

Heated crude oil enters near the bottom of a tall fractionating column which is hot at the bottom and gets cooler towards. Industrial fractional distillation of crude oil generates fractions that have distinctly different boiling points properties and uses. A vigreux column with glass indentations b steel wool column made simply be loosely inserting steel wool into the cavity of a fractionating column similar to a west condenser but wider c glass beads filled in. It s possible to isolate chemicals using simple distillation but it requires careful control of the temperature because only one fraction can be isolated at a time.
