Oren Hydrocarbons Interview Questions and Answers

Aptitude test with analytical skills required

Q1. What is distillation
Ans. 
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
• Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to collect the separated components.

• The component with the lower boiling point will vaporize first and be collected, leaving behind the component with the higher boiling point.

• Examples of distillation include the separation...read more
