The Tanzanian and Italian Petroleum Refining Co Ltd (Tiper) refinery at Dar es Salaam, Tanzania was originally built between 1963 and 1966 and commissioned in 1969. It is a topping and reforming refinery with a nameplate distillation capacity of 875 ktonnes per annum (17,500 bpd) but is generally operating at approximately 60% of rated capacity. The refinery is a limited company incorporated in Tanzania under the parastatal Tanzania Petroleum Development Corporation (TPDC). The shareholders of the company are the Treasury of Tanzania (50%) and Agip (50%) who are also the refinery’s operators.

Since 1991 the refinery has been undergoing rehabilitation and modernisation in order to increase its efficiency, safety standards and output. The rehabilitation is intended to restore output to its nominal capacity despite a recommendation by the World Bank, strongly opposed by the Tanzanian government, that the refinery be closed. The Tanzanian government is of the opinion that the refinery is essential to the Tanzanian economy and are working to keep it operating.

The upgrading programme also includes a revamp of the boiler and the installation of a new instrument panel. TPDC has also considered installing conversion units in order to boost the yield of white product.
