The gasoline production complex of Iran's Isfahan refinery is now 95 per cent complete, IRIB News reported.
After the foreign contractors withdrew from the development project of the complex, Iranian contractors carried out the project.
Isfahan refinery's gasoline production complex is projected to come on stream in spring.
Once the complex comes on stream, some 3 million liters would be added the refinery's daily gasoline production capacity.
The project would be completed at the cost of 4.7 trillion rials (some $383.5 million based on the official rate of USD).
The Shazand oil refinery's RFCC gasoline prediction unit will also come on stream in near future.
Iranian president Mahmoud Ahmadinejad will inaugurate the project. The gasoline production unit will come on stream at a cost of 3.5 billion dollars.
By implementing the project, the refinery's gasoline output would be increased to 16 million litres from the previous figure of four million litres.
Iranian Oil Minister Rostam Qasemi said on September 21, 2012, that Iran will boost its gasoline production capacity by 10 million litres in the near future.
Once the third development phase of the Abadan Oil Refinery, the Lavan refinery's gasoline production unit, and the RFCC unit of the Shazand Refinery come on stream, the country's clean gasoline output, which meets Euro-4 and Euro-5 standards, will reach 25 million liters, from the current figure of 12 million.
Iran will start selling gasoline conforming to Euro-4 standard in 8 cities from February.
The move is a part of Iran's efforts to reduce air pollution. Motor vehicles account for 70 percent of air pollution in the Iranian capital city. Tehran says all carmakers would be obliged to manufacture cars meeting Euro-4 and Euro-5 standards.
