Petromidia Refinery is the largest Romanian oil refinery and one of the largest in Eastern Europe, located in Năvodari, Constanţa County. It has an annual processing capacity of 4.8 million tonnes/year or 100,000 bbl/d (16,000 m3/d). The refinery is supplied with oil through an oil terminal located in the Port of Midia that can accommodate ships up to 24,000 DWT or by a pipeline of 40 kilometres (25 mi) which has a terminus in the Port of Constanţa.
The refinery was founded in 1975 as the Midia Năvodari Petrochemical Factory on a 480 hectares (52,000,000 sq ft) plot of land located in Năvodari, Constanţa County. The design and construction of the complex took two years and was based on Romanian technology and foreign licenses. In 1991 the Midia Năvodari Petrochemical Factory was transformed into a joint stock company and the name was changed to SC Petromidia SA.
Between 1997 and 2000 the state tried to privatise the company several times. The first procedure was undertaken in 1997 and negotiations were held with a consortium made by South Korean Daewoo, Swiss company Glencore, and Petromidia USA (local representative of the Windmill company). Between July 1998 and January 1999 a new round of negotiations were finalised and the Turkish company Akmaya was chosen as a strategic investor, offering a per share price of US$ 10.1. On November 1, 2000, the Romanian Property Fund (Romanian: Fondul Proprietăţii de Stat) sold a stake of 69,991% of the complex to Rompetrol Group BV Rotterdam at a price of US$ 50.517 million, equivalent to US$ 2 per share. The value of the transaction was US$ 615 million, of which US$ 225 million was for modernisation works and other investments and US$ 340 million was for various debts (US$ 169 million for debts to the state and US$ 171 million to banks and other creditors) . Rompetrol also changed the name of the refinery to Rompetrol Rafinare. In April 2004 Rompetrol Rafinare was listed on the Bucharest Stock Exchange under the symbol RRC. Soon it became one of the most important listed companies and in December 2004 it was included in the BET 10 index.
Petromidia is the only Romanian refinery located on the Black Sea shore, thus having the advantage of being supplied directly through the Midia oil terminal located in the Port of Midia capable of receiving oil tankers up to 24,000 DWT or the 40 kilometres (25 mi) pipeline starting in the Port of Constanţa. The refinery has an annual processing capacity of 4.8 million tonnes/year, or 100,000 bbl/d (16,000 m3/d), and storage facilities for up to 400,000 m3 of oil.
