Quiz Answer Key and Fun Facts

1. The processing unit designed to make the first separation of crude oil is called the:

Answer: Crude distillation unit

Crude distillation is usually the first step in the refining of crude oil, and is designed to separate the various boiling point "cuts" in crude oil.

2. Which of the following is not a primary product of the refining process?

Answer: Polyethylene

Polyethylene is a plastic product from petrochemical processes. Refineries also produce jet fuel, petroleum coke, and fuel oil, as well as a few other niche products.

3. Which country uses the most refinery products?

Answer: United States

The United States is by far the largest user of refined crude oil products.

4. Two methods of hydrogen generation for use within a refinery are:

Answer: Catalytic Reforming and Steam/Methane Reforming

The two primary methods of hydrogen production are steam/methane reforming and catalytic reforming. partial oxidation/gasification is another method used in some facilities.

5. Which of the following processes is designed to remove sulfur from the gasoline and diesel products?

Answer: Hydrotreater

Hydrotreaters remove sulfur and nitrogen impurities from refining products by using pressure, temperature, and a catalyst to turn sulfur in the products into Hydrogen Sulphide.

6. Which company built the last new refinery in the United States in 1976?

Answer: Marathon Petroleum

The Marathon refinery in Garyville, Louisiana was built in 1976. Motiva Refining LLC is currently (in 2009) building an expansion in Port Arthur, TX which will more than double its original capacity.

7. Which of the following refinery processes is considered "semi-batch" (as opposed to "continuous")?

Answer: Delayed coking

Delayed coking uses time and temperature to crack the heaviest cut of crude oil into usable products (mostly naphtha, gasoil, and petroleum coke). After a coke drum is filled, it is taken off-line, steamed, quenched with water, and finally "cut" out of the drum with high pressure water.

Answer: Hydrogen Make-up Compressor

FCC units are traditionally one of the most profitable units in the refinery, as they turn a heavy and lower value portion of the crude cut into gasoline/petrol and other products.

FCC units do not use Hydrogen compressors.

9. The feed to a catalytic reforming unit is always hydrotreated. Why is this?

Answer: Hydrotreaters remove sulfur, a Reformer catalyst poison

Catalytic reformers use a platinum-based catalyst which is poisoned by sulfur products.

10. Petroleum refineries have many processes designed to minimize pollution to water and air. Which of the following processes are designed primarily as environmental controls?

Answer: All of these

Refineries also use flue gas scrubbers, low-NOX furnace burners, and flare gas recovery systems to minimize air emissions. Other water protection systems include reverse osmosis treatment, corrugated plate interceptors, and rainfall collection.
