Other Grades
Other grades of Nigerian crude oil are Qua Iboe crude oil, Brass River crude oil, and Forcados crude oil. The Cabinda crude oil is a common grade of crude oil produced in Angola. The Bonny Light is in high demand specifically by American and European refineries. It is therefore a major source of income generation from the oil rich nation.
Low Pour Fuel Oil
Low pour fuel oils (LPFO) are products derived from crude oils with the major components being residuals or bottoms from petroleum refining operations. At times, the residuals are blended with gas oil and light fuel oil to improve its atomizing capability in burners. The chemical nature of LPFO is quite complex and depends on the source of crude oil as well as the refining process employed in producing the fuel oil.
