Question

During fractional distillation, the crude petroleum is heated to a temperature of about:

• A. ${600}^{\circ }C$
• B. $400$ to ${500}^{\circ }C$
• C. ${200}^{\circ }C$
• D. ${100}^{\circ }C$

Answer 1

The correct option is B $400$ to ${500}^{\circ }C$

Fractional distillation is the separation of a mixture into its component parts or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. During fractional distillation, crude petroleum is heated to a temperature of about 400 to 500C. which makes most of the oil evaporate. The fluid then enters the column. As the vapour moves up through the fractionator, each fraction cools and condenses at a different temperature.
