Overview of the PH refinery
The Port Harcourt Refineries consist of two units, with the old plant having a refining capacity of 60,000 barrels per day (bpd) and the newer plant capable of processing 150,000 bpd, totalling 210,000 bpd.
The refinery has not operated at full capacity for over two decades. It was last shut down in March 2019 for initial repair works, following the engagement of Italy’s Maire Tecnimont as the contractor for the complex's review, with Eni serving as the technical advisor.
In 2021, NNPC Ltd announced the commencement of repairs at the refinery, supported by a $1.5 billion approval from the Federal Executive Council (FEC).
On 21 December 2023, the Nigerian government announced the mechanical completion and the flare start-off of the refinery.
