Upgrading the quality of refined products has always been a key issue with treatment facilities. Currently, with about $8.72 billion investment, 13 quality upgrade projects are underway at 9 refineries, some of which will become operational by 20 March 2024. These projects are not limited to upgrading the quality of fuel produced at refineries; rather, they would include a variety of projects including reduction of heavy products’ output and launching a coke production unit at refineries. These projects have been highlighted in the 7th National Economic Development Plan.
