Refineries play a vital role in the world’s energy market as well as the oil and gas industry by transforming crude oil into valuable products such as, diesel oil, petrol, kerosene, and liquefied petroleum gas. Oil has been the most important energy source for decades now and refined oil can be an extremely valuable export.
It can be tremendously beneficial for a country to have a supply of refined oil products so they are not dependent on foreign sources of energy. Instead, a country producing oil can create jobs, attract foreign investments, and even export oil in exchange for a significant source of foreign revenue.
The countries with the highest number of largest refineries in the world are South Korea and the United States of America. This list is based on the processing capacity of each refinery. Check them below:
