Dangote Group has signed a contract valued at over $350 million with India’s state-owned Engineers India Limited (EIL).
The development was disclosed by EIL in a statement released recently. Under the agreement, EIL will serve as the Project Management Consultant (PMC) and Engineering, Procurement and Construction Management (EPCM) consultant for the expansion.
This replicates the role it played in the delivery of the existing 650,000 barrels-per-day refinery, which was commissioned in 2024.
The Refinery will be expanded from 650,000 barrels per day to 1.4 million bpd.
The expansion will be executed through the addition of a second processing train and will focus on the production of Euro VI–compliant fuels.
Beyond refining, the project also includes a major scale-up of petrochemical output. Dangote plans to increase polypropylene production from 830,000 tonnes per annum to 2.4 million tonnes per annum by revamping its existing polypropylene unit, installing an additional 1.2 million-tonne unit, and adding a 750,000-tonne UOP Oleflex unit to boost propylene feedstock supply.
