That has materialized after installing the isomerization and diesel treatment units. Energy management, waste reduction and using heavy crude oil as feedstock are among the outstanding features of this project.Furthermore, the gasoline production at this refinery has increased by about 5 ml/d, while the quality of gasoil has been upgraded to euro-5 standards.Isfahan Refinery GasoilThe process development project, upgrading the quality of products and optimization of Isfahan refinery to increase gasoline output from 41,000 b/d to 120,000 b/d has been fulfilled. That has led to an increase in the quantity and quality of gasoline by 3 ml/d of euro-5 fuel, removal of octane boosting materials, possibility of premium gasoline production as well as euro-4 gasoil production. The gasoline production, as well as other related units in this project is over and other projects are being completed. The gasoil dehydration project at this refinery would bring the euro-grade gasoil output to 20 ml/d. Isfahan refinery is currently supplying 12 ml/d of high-quality gasoline, largely contributing to the supply of high-quality fuel.High-Quality Fuel Production NorthwestIn August 2019, Tabriz refinery development project became operational to allow the distribution of 3 ml/d of high-quality gasoline in north and northwest Iran. The gasoil desulfurization unit of Tabriz Oil Refining Company became operational tentatively in September 2018. The refinery is adding 6 ml/d of euro-5 gasoil to the country’s output. The project for upgrading the quality of Tabriz refinery’s products include designing and installing a CCR naphtha reforming unit and installing a gasoil refining unit to reduce the sulfur content of gasoil based on euro-5 standards.The development project is aimed at facilitating euro-5 high-octane gasoline production, removal of MTBE from gasoline and supply of 750,000 b/d of gasoline as well as euro-5 gasoil production.Tehran Refinery’s 12 ml/d GasoilThe production of high-quality gasoline and gasoline production at Tehran refinery officially started in August 2012 as gasoline production and optimization projects came on-stream. The refinery is currently producing 7 ml/d of euro-grade gasoline and 12 ml/d of euro-grade gasoil. The main objective behind improving the refinery’s products was to contribute to national environmental objectives and reduce the sulfur content of gasoil and kerosene based on euro-5 standards.Euro-Grade Gasoline at LavanLavan refinery’s first cargo of euro-5 gasoline (8,000 liters) was loaded last October to be delivered to Bandar Abbas for consumption. The first phase of process improvement at this refinery with the objective of increasing capacity from 30,000 b/d to 55,000 b/d came online in May 2011 while the dehydration and light naphtha isomerization units became operational in June 2013. The dehydrating unit for middle distillate products – kerosene and gasoil – came online in 2015 while the gasoil and kerosene desulfurization unit came online two years after, in order to supply euro-4 and euro-5 products.The capacity enhancement plan at Lavan refinery was launched in order to enhance capacity, reduce pollutants, upgrade the quality of products to euro-5 grade, increase light and valuable products (mainly gasoline), reduce low-quality and heavy products (fuel oil) and reduce energy consumption at the facility. The project was aimed at increasing the refining capacity to 50,000 b/d, increasing gasoline production based on euro standards, desulfurizing products and supplying euro-5 products.Abadan Refinery DevelopmentThe main objective behind the implementation of this project was to set up a new CAT cracking unit, maximize euro-5 gasoline production based on the possibility of feedstock supply, reduce fuel oil output and create value-added at the refinery. The gasoline production units as well as related units of this refinery are over and the second phase of this project is forecast to have progressed 65% by next March. After finalization of the Abadan refinery development project, a new refinery will be born out with a production capacity of 15 ml/d of high-quality gasoline.
