What is the first substance to be separated out in petroleum refining?
Understand the Problem
The question is asking about the initial product extracted during petroleum refining. This requires knowledge about the petroleum refining process and the boiling points of different hydrocarbons.
Answer
The first step in petroleum refining is separation via fractional distillation.
The first step in petroleum refining is the separation of crude oil into different components based on their boiling points through a process called fractional distillation.
Answer for screen readers
The first step in petroleum refining is the separation of crude oil into different components based on their boiling points through a process called fractional distillation.
More Information
The separated components are called fractions or distillates, which include products like gasoline, diesel, kerosene, and bitumen.
Tips
A common mistake is thinking that a specific substance like gasoline is the first to be separated. Fractional distillation separates multiple components simultaneously based on boiling points.
