What is a refinery?
Petroleum refineries convert crude oil and other liquids into many petroleum products that people use every day. Most refineries focus on producing transportation fuels. On average, U.S. refineries produce, from a 42-gallon barrel of crude oil, about 19 to 20 gallons of motor gasoline, 11 to 12 gallons of distillate fuel, most of which is sold as diesel fuel, and 4 gallons of jet fuel. More than a dozen other petroleum products are also produced in refineries. Petroleum refineries produce liquids the petrochemical industry uses to make a variety of chemicals and plastics.
Refineries operate 24/7
A refinery runs 24 hours a day, 365 days a year and requires a large number of employees. A refinery can occupy as much land as several hundred football fields.
