Oil installations at the Dangote refinery during the opening ceremony in Lagos, Nigeria, Monday, May 22, 2023. Nigerian President Muhammadu Buhari on Monday opened the oil refinery, with hopes it would help the energy-rich country achieve self-sufficiency and become a net exporter of refined petroleum products. The $19 billion facility built by Aliko Dangote, Africa’s wealthiest man, in Nigeria’s economic hub of Lagos is one of the world’s biggest oil refineries and has a capacity of 650,000 barrels per day.
