please mark as brainlist

Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.[1][2][3]

Petroleum refineries are very large industrial complexes that involve many different processing units and auxiliary facilities such as utility units and storage tanks. Each refinery has its own unique arrangement and combination of refining processes largely determined by the refinery location, desired products and economic considerations.

Some modern petroleum refineries process as much as 800,000 to 900,000 barrels (127,000 to 143,000 cubic meters) per day of crude oil.

Answer 2

An petroleum refinery is an industrial plant that refines crude oil into petroleum products such as diesel, gasoline and heating oils. Petroleum refineries essentially serve as the second stage in the production process following the actual extraction of crude oil by rigs. The first step in the refining process is distillation, where crude oil is heated at extreme temperatures to separate the different hydrocarbons.
