Question

A student drew the following flowchart
Oil rig -> Pipeline -> Tanker truck -> Refinery
Which process is shown?

A. Crude oil processing
B. Surface mining
C. Coal burning
D. Hydraulic fracturing

Answer 1

Hello there!

The answer is A. crude oil processing.

Before used, crude oil is processed which then produces petroleum products of different molecular weights and application.

Here is the flow of the process:

1. To get oil from the ground, oil rig is used.

2. The oil is then transferred to a tanker truck through a pipeline. The tanker truck will transport the crude oil to the refinery station.

3. In the refinery station, the crude oil is processed such as distillation which produces different petroleum products based on their molecular weight.

I hope this will help you!

Answer 2

"The flow chart given defines the crude oil processing. All the oils that are taken from the mines are called crude oils. These oils undergo refining process and made into "useful products" such as diesel, liquified petroleum gas, jet fuels, etc.

The three stages of the refining process are:

1. Separation: The molecules are "separated" according to their weight.
2. Conservation: The oils are converted into gas, gasoline, and diesel.
3. Treating: Pollution causing particles are removed."
