The primary purpose of a petroleum refinery is to separate crude oil into its various components, such as gasoline, diesel fuel, and heating oil, through a process called fractional distillation.

Trucks are not commonly used to transport large quantities of petroleum products over long distances, as they are more expensive and less efficient than pipelines, tanker ships, and rail cars.

Petroleum storage terminals are used to store refined petroleum products, such as gasoline, diesel fuel, and heating oil, before they are distributed to retail outlets or end users.

Petroleum marketers are responsible for distributing petroleum products, such as gasoline, diesel fuel, and heating oil, to retail outlets, such as gas stations and convenience stores.

The cost of crude oil is the main factor that determines the price of petroleum products, as it accounts for a significant portion of the total cost of production.

Blending is the process of mixing different types of petroleum products, such as gasoline and ethanol, to create a desired final product with specific properties.

Petroleum pipelines are used to transport crude oil from production fields to refineries, refined petroleum products from refineries to storage terminals, and petroleum products from storage terminals to retail outlets.

Cracking is the process of converting heavier petroleum fractions, such as vacuum gas oil, into lighter, more valuable fractions, such as gasoline and diesel fuel, by breaking down the larger molecules into smaller ones.

Petroleum storage tanks are used to store refined petroleum products, such as gasoline, diesel fuel, and heating oil, before they are distributed to retail outlets or end users.

Reforming is the process of converting low-octane gasoline into high-octane gasoline by rearranging the molecular structure of the hydrocarbons.

Petroleum distribution terminals are used to store and distribute petroleum products, such as gasoline, diesel fuel, and heating oil, to retail outlets, such as gas stations and convenience stores.

Blending is the process of mixing two or more petroleum fractions, such as gasoline and ethanol, to create a desired final product with specific properties.

Petroleum pipelines are used to transport crude oil from production fields to refineries, refined petroleum products from refineries to storage terminals, and petroleum products from storage terminals to retail outlets.
