The majority of world's 10 largest refineries are situated in the Asia Pacific region, with India hosting the world's largest refinery complex, followed by Venezuela and South Korea. Hydrocarbons-technology.com lists the top 10 large oil refineries globally, based on processing capacity.


Jamnagar refinery is the world's largest oil refinery

Reliance Jamnagar Refinery, India

Jamnagar refinery is the world's largest oil refinery with an aggregate capacity of 1.24 million barrels per day (bpd). The refinery complex is located at Jamnagar in Gujarat, India. It is owned and operated by Reliance Industries.

The refinery complex is spread across 7,500 acres and has more than 50 process units which refine the basic feedstock, crude oil to obtain various finished products.

The world's largest refinery took three years to complete and involved about $6bn of investment.

The refinery consists of hydrodesulphurisation, catalytic reforming, fluid catalytic cracking and delayed coking units. It also includes sulphur recovery, hydrogen generation, merox treating and TAME (Tertiary Amyl Methyl Ether) units.
