Refinery Exit ticket

What is the primary purpose of distillation in an oil refinery?

• To decrease the pressure of crude oil

• To increase the boiling point of crude oil

• To separate crude oil into usable products

• To clean the crude oil

What determines the boiling point of a liquid?

• The color of the liquid

• The size and shape of its molecules

• The temperature of the surrounding environment

• The depth of the liquid

What are boiling fractions in oil refining?

• A method to cool down the oil

• The temperature at which oil starts to boil

• Groups of hydrocarbons with similar boiling points

• Types of equipment used in refineries

Why is vacuum distillation used in oil refining?

• To increase the pressure on the liquid

• To make the water boil at room temperature

• To boil heavy fractions at lower temperatures

• To separate water from oil

What is the main goal of cracking in oil refining?

• To combine smaller molecules into larger ones

• To increase the pressure of heavy oil

• To clean the heavy oil

• To break down heavy oil molecules into lighter ones

What role does a catalyst play in cracking?

• It slows down the chemical reaction

• It changes the color of the oil

• It stimulates the chemical reaction without being consumed

• It increases the boiling point of oil

What is the purpose of catalytic reforming?

• To decrease the octane number of gasoline

• To convert straight run gasoline into high octane gasoline

• To separate water from gasoline

• To cool down the gasoline

What is straight run gasoline?

• Gasoline with added water

• Gasoline with a high octane number

• Gasoline distilled directly from crude oil

• A type of synthetic gasoline

How are heavy oil molecules changed in the cracking process?

• By mixing them with water

• By cooling them to very low temperatures

• By heating them to very high temperatures

• By exposing them to high pressure

What is the result of catalytic reforming?

• Decrease in the production of petroleum gases

• Production of high octane gasoline

• Production of diesel fuel

• Conversion of heavy oil into asphalt
