Kuwait's Al-Zour Refinery Named Among World's Top 10 Oil Refineries
Kuwait's Al-Zour Refinery, which started operations in 2022, has been ranked eighth globally among the top 10 oil refineries. It has a refining capacity of 615,000 barrels per day. This capacity represents 8.54% of the total output from the world's ten largest refineries, which collectively process 7.197 million barrels daily.
The Global Data report, as reported by Arab Times, based on Offshore Technology's findings, highlights that Al-Zour Refinery is the only refinery from the Gulf and Arab regions to be listed among the top ten worldwide. Owned by Kuwait Integrated Petroleum Industries Company (KIPIC), it scored 7.1 on the net refining index and is designed to process heavy crude oil into high-value derivatives.

The report emphasises that Al-Zour Refinery significantly enhances Kuwait's refining capacity, enabling the country to better serve regional and global markets. The global oil industry supports economies and industries worldwide through a vast network. With 825 active refineries currently operating, the sector is poised for substantial growth. Crude distillation unit (CDU) capacity is expected to rise by 15 percent between 2023 and 2027.
According to GlobalData's refinery database compiled by Offshore Technology in 2022, the United States leads in crude distillation unit capacity, followed closely by China and Russia.
The world's largest active oil refineries by crude distillation unit capacity in 2022 include Venezuela's Paraguana Refinery, which processes 955,000 barrels per day. Established in 1949, this facility converts heavy crude oil into valuable products and remains vital for Venezuela's oil exports.
