Dangote Refinery, Africa’s largest single-train petroleum refinery, has signed a landmark contract with U.S. industrial giant Honeywell International to execute a significant capacity upgrade that will boost the facility’s crude processing capability from the current 650,000 barrels per day to an ambitious 1.4 million barrels per day.

The multi-billion-dollar project, described by sources close to the deal as one of the largest refinery expansion initiatives globally in recent years, will involve the installation of advanced process units, automation systems, and energy-efficiency technologies supplied and integrated by Honeywell UOP and Honeywell Process Solutions.

Aliko Dangote, President and CEO of Dangote Industries Limited, confirmed the partnership, stating: “This strategic collaboration with Honeywell will position the Dangote Refinery as one of the top five largest refineries in the world by capacity.

The upgrade will not only enhance our ability to meet Nigeria’s complete refined products demand but also establish the refinery as a major export hub for gasoline, diesel, jet fuel, and petrochemicals across Africa and beyond.

”The expansion is expected to be implemented in phases, with key units including additional crude distillation, hydrocracking, and catalytic reforming modules.

Honeywell’s proprietary technologies are anticipated to improve yield of high-value products while reducing energy consumption and emissions.Upon completion, the 1.4 million bpd Dangote Refinery will surpass the current global top-tier facilities such as Reliance Industries’ Jamnagar Refinery (1.24 million bpd) and Paraguay’s planned 1.2 million bpd project, cementing its status as the world’s largest single-train refinery.

The project is expected to create thousands of direct and indirect jobs during the construction and commissioning phases and further reduce Nigeria’s dependence on imported refined petroleum products.

A spokesperson for Honeywell confirmed the award, saying the company was “honored to partner with Dangote on this transformative project that will reshape the African downstream landscape.

”Detailed timelines and the exact value of the contract were not disclosed, but industry analysts estimate the expansion could exceed $5–7 billion in total investment.

The statement said: Dangote Group is pleased to announce that it has entered into a strategic partnership with Honeywell International Inc to support the next phase of expansion of the Dangote Petroleum Refinery.

This collaboration will provide advanced technology and services that will enable the refinery to increase its processing capacity to 1.4 million barrels per day by 2028, marking a major milestone in our long-term vision to build the world’s largest petroleum refining complex.

Through this agreement, Honeywell will supply specialised catalysts, equipment, and process technologies that will allow the refinery to process a broader slate of crude grades efficiently and to further enhance product quality and operational reliability.

Honeywell, a global Fortune 100 industrial and technology company, offers a wide portfolio of solutions across aviation, automotive, industrial automation, and advanced materials.

Honeywell’s division UOP has been a technology partner to Dangote since 2017, providing proprietary refining systems, catalyst regeneration equipment, high performance column trays, and heat exchanger technologies that support our best-in-class operations.

Dangote Group is also advancing its petrochemical footprint. As part of the wider collaboration, we are scaling our polypropylene capacity to 2.4 million metric tons annually using Honeywell’s Oleflex technology.

Polypropylene is a key industrial material widely used across packaging, manufacturing, and automotive applications.In addition to refining expansion, Dangote Group is progressing with the next phase of its fertiliser growth plan in Nigeria. We will increase our urea production capacity from 3 million metric tons to 9 million metric tons annually.

The existing plant consists of two trains of 1.5 million metric tons each. The expansion will add four additional trains to meet growing demand for high-quality fertiliser across Africa and global markets.

Dangote Group remains fully committed to delivering world-class industrial capacity, strengthening Nigeria’s energy security, and driving sustainable economic growth through long-term investment, innovation, and strategic global partnerships.
