Tabriz Oil Refining Company was designed in 1975, and after the completion of the construction steps in February 1978, it was launched with a nominal capacity of 80,000 barrels per day. Increasing the production capacity to 110,000 barrels in 1992 with the efforts of internal experts and specialists is a great honor that has been figured out in this company. At present, Tabriz Oil Refining Company has a share of about 7% of the crude oil refining capacity of the whole country with conversion to original and specific products. It supplies a part of the liquid fuel required in the North-West of the country (East-Azerbaijan, West-Azerbaijan, Zanjan, and Kurdistan).
