Nigeria's President Muhammadu Buhari will commission a $19bn (£15bn) single-train oil refinery shortly - the largest of its kind in the world and built by Africa’s richest person, billionaire businessman Aliko Dangote.
The government hopes the refinery will turn Nigeria, Africa's biggest oil producer, from an importer of refined fuels to an exporter and put an end to recurring fuel shortages while creating tens of thousands of jobs.
The size of about 130 football fields, Dangote Industries has billed it as the world's largest single-train petroleum refinery, meaning it will have only one crude distillation unit.
The project, launched in 2016, is located in the Lekki area of Lagos State, off the Atlantic Ocean, and is expected to process 650,000 barrels of crude oil a day.
The refinery, 20%-owned by the state, is not expected to operate at full capacity until 2025.
"At full capacity it can meet 100% of the Nigerian requirement of all refined products and also have surplus for export," Dangote Industries said in a statement last week.
Mr Buhari will commission the plant in one of his last public acts before he steps down as president next Monday following two terms in office.
He will hand power to Bola Tinubu, who won disputed presidential elections in February.
