Oil Refineries

What do engineers and scientists do at an oil refinery?

• Turn raw crude oil into valuable fuels, lubricants, and components

• Extract raw crude oil

• Build refinery equipment

• Control traffic near the refinery ANSWER

What happens to oil after it is superheated in the refining process?

• It turns into gasoline

• It becomes vapor

• It cools immediately

• It solidifies

Which liquids require less processing to be used in cars and trucks?

• Light and medium-weight liquids

• Heavy liquids

• All liquids

• Vaporized liquids

What is the purpose of the cracking process in refining?

• To cool the oil vapor

• To break down heavy oil into lighter, more valuable fluids

• To blend gasoline grades

• To separate sulfur from gasoline

What is naphtha turned into during the reforming process?

• Diesel

• Lubricant

• Gasoline-like molecule

• Hydrogen gas

What is gasoline blended to achieve?

• Octane standards for different gasoline grades

• A uniform color

• Lower sulfur content

• Reduced emissions

What does the treating process remove from gasoline molecules?

• Carbon

• Water

• Impurities like sulfur

• Nitrogen

What happens to the sulfur removed during the treating process?

• It is released into the atmosphere

• It is used as fertilizers and in pharmaceuticals

• It is stored in tanks

• It is mixed back into gasoline

By how much has refinery production increased since the 1970s?

• 20%

• 30%

• 40%

• 50%

What is one benefit of the innovative work done at refineries?

• It reduces oil extraction costs

• It keeps prices low for fuels and products

• It reduces the need for refineries

• It eliminates environmental impacts
