The Exciting World of Petroleum Liquids!

What are the two main categories that the USCG separates petroleum liquids into?

A. Liquid and gas

B. Crude oil and refined petroleum products

C. Light and heavy

Answer:

The USCG divides petroleum liquids into two categories: crude oil and refined petroleum products.

Explanation: The United States Coast Guard (USCG) separates petroleum liquids into two major categories. Crude oil is raw petroleum extracted from the ground, while refined petroleum products are substances processed from crude oil in a refinery, such as gasoline and diesel fuel.

Crude oil is unprocessed petroleum directly extracted from the ground. It gets its name from the fact it is 'crude', or raw. This oil can vary in color, density, and sulfur content which can affect its commercial value and how it is processed.

Refined petroleum products are substances that have been processed and transformed from crude oil in a refinery. These include gasoline, diesel fuel, heating oil, jet fuel, and others. The refining process removes impurities and breaks down the crude oil into its various components for a variety of uses.
