Refineries are the systems that separate and clean crude oil before converting it into automotive oil, LPG gas, petroleum, and other valuable products. The countries that import oil from the oil-reserved countries are India, China, and the United States. There are thousands of refineries around the world, both large and small, owned by private and public companies.
The largest oil refineries are built on the availability of crude oil in specific locations that are also convenient for transportation to deliver fuel to various parts of the country. The ‘Jamnagar Refinery‘ is India’s largest oil refinery, with a capacity of 1,240,000 barrels per day, and SK Energy Co., Ltd. Ulsan Refinery is South Korea’s second-largest oil refinery, with a capacity of 1,120,000 barrels per day.
