Shiraz Oil Refinery was established in 1970 on the outskirts of Zarghan province 22 km from Shiraz City. According to ongoing policies, the refinery's administrative structure was rearranged into a company set up in 1998 and subsequently named Shiraz Oil Refining Co. and registered as a public joint-stock company in 2009.
According to its articles of association, the company is entitled to engage in the commissioning and operation of industrial units and conduct activities in production, marketing, sale and export of different oil products, various chemicals and other similar products. It can also conduct activities in receiving, exchanging and purchase of refinery feedstock such as crude oil, gas condensates, natural gas and by-products of petrochemical industries from the National Iranian Oil CO.
