TOR is the premier and 45,000 bpsd wholly owned Ghanaian refinery that has been refining crude oil since 1963.
The 14,000 bpsd Residue Fluid Catalytic Cracker (RFCC) Unit converts atmospheric residue to higher value finished products.
The refinery is situated in Tema about 24 kilometers east of the capital, Accra. It was originally named the Ghanaian Italian Petroleum (GHAIP) Company and incorporated as a Private Limited Liability Company under the Companies Ordinance (Cap 193) on December 12, 1960.
It was 100% owned by the ENI Group (Ente Nationalie Indrocarburi) of Italy. The Government of Ghana bought all the shares of GHAIP in April 1977 and became sole shareholder.
In 1990 the name was changed to the Tema Oil Refinery.
