Inside the Dangote Refinery: The World’s Largest Single-Train Plant

Before you evaluate an IPO, it helps to understand the asset behind it. Dangote Petroleum Refinery sits on a roughly 6,180-acre site in the Lekki Free Zone (Ibeju-Lekki), Lagos State, Nigeria, and is supplied in part by a subsea pipeline network reported at around 1,100 kilometres. It’s commonly described by the company and independent industry outlets as the world’s largest single-train refinery — meaning it processes crude through one continuous production line rather than several smaller parallel units.

The refinery was commissioned in May 2023, began processing crude in early 2024, and started producing petrol (PMS) in September 2024, according to public reporting. In a statement on February 11, 2026, the company said it had reached its full designed capacity of 650,000 barrels of crude oil per day, following optimization of its crude distillation and petrol production units. That’s a significant operational milestone — refineries of this scale often take years to ramp from first output to full nameplate capacity, and delays are common industry-wide, not unique to Dangote.

At full capacity, the refinery is designed to produce large volumes of petrol, diesel, jet fuel, and other products, with the stated goal of ending Nigeria’s heavy reliance on imported refined fuel and, potentially, turning the country into a net exporter of refined products. In October 2025, Dangote also announced plans to expand capacity further, to a reported 1.4 million barrels per day, alongside new petrochemical investments — though expansion plans of that scale typically unfold over years and are worth tracking rather than assuming.

Construction costs for the project have been reported at different figures over time, commonly cited in the range of roughly $19–20 billion, reflecting how the budget grew from original estimates. Nigeria’s state oil company, NNPC, holds a 20% equity stake in the refinery, a stake that predates and is separate from the public shares now being contemplated in the IPO.

Why this matters for the IPO: an operating, revenue-generating asset at full capacity is a materially different investment case than a pre-revenue construction project. Investors evaluating the eventual offer will want to look closely at actual throughput, product yield, and revenue data once the company discloses it in a prospectus — rather than relying on capacity figures alone.
