The refinery produces a range of petroleum products including liquefied petroleum gas (LPG), naphtha, gasoline, diesel, fuel oil, and Lube Base Oil Group I. The facility underwent upgrades completed in 2016 under the "hygiene and value-added products (UHV)" project to improve efficiency and product yields.​

Petrochemical Complex

The petrochemical operations have a total capacity of 3,137 kilotonnes per annum (KTA), producing olefins, aromatics, styrenics, polyolefins, and polystyrenics. IRPC is a naphtha-based petrochemical producer and operates as Southeast Asia's leading polypropylene (PP) producer with 775 KTA capacity. The complex includes approximately 728,000 tonnes annual capacity for olefins products and 367,000 tonnes for aromatics.​

Integration Strategy

IRPC operates as a fully integrated complex where refinery operations feed the petrochemical units, with the refinery optimally running at approximately 70% capacity to enable petrochemical plants to operate at 100% utilization. This integration strategy focuses on value-added petrochemical products that offer higher margins compared to conventional refining products.
