RoydadNaft – <\/a><\/span>\u00a0The Imam Khomeini Oil Refinery in Shazand has completed its most extensive overhaul in a decade, a $60 million project involving 5,000 specialized workers that increased production capacity by at least 30% and significantly improved operational reliability. The work ensures high-quality production for at least the next four years without interruption, refinery officials said.<\/p>\n

The large-scale maintenance program marks one of the most comprehensive overhauls ever conducted in Iran\u2019s refining industry. The project included full refurbishment of all refinery equipment and half of its main processing units \u2014 a process that officials described as a \u201ccomplete reconstruction.\u201d<\/p>\n

Mohammad Sepehri-Rad, head of maintenance at the refinery, said in an interview with Shana that the overhaul began with Phase 1 units and later expanded to Phase 2. \u201cAll units except the RFCC (residual fluid catalytic cracking) unit have now been fully overhauled,\u201d he said.<\/p>\n

According to Sepehri-Rad, this maintenance cycle differed sharply from previous ones. \u201cWe essentially rebuilt the units rather than just conducting routine repairs,\u201d he said. \u201cThe refurbishment of the RFCC reactor section was carried out for the first time in Iran after 10 years, providing invaluable experience for our teams and domestic manufacturers.\u201d<\/p>\n

Cost and Time Savings Through Domestic Expertise<\/strong><\/p>\n

Sepehri-Rad said that maximizing domestic capabilities not only strengthened technical expertise within the company but also reduced costs and repair time. Of the 5,000 personnel involved, 3,000 were Iranian specialists. \u201cRelying heavily on internal capacity allowed us to minimize expenses and shorten the duration of the overhaul,\u201d he said.<\/p>\n

He added that one of the most important outcomes was improved unit reliability and a significant reduction in emissions. \u201cThese upgrades allow the refinery to operate efficiently for the next four years without concerns about product quality,\u201d he said.<\/p>\n

While foreign consultants were involved in some planning aspects, all engineering, fabrication, and execution were carried out domestically. \u201cThis project creates a strong foundation for the company\u2019s future initiatives,\u201d Sepehri-Rad said.<\/p>\n

\u00a0Reactor and Regenerator Refurbished for the First Time in Iran<\/strong><\/p>\n

Among the project\u2019s biggest challenges, Sepehri-Rad cited the overhaul of reactor and regenerator sections \u2014 a first in Iran. Domestic engineering teams handled much of the work independently. \u201cOne of the most demanding stages was safely separating the reactor head, which was completed successfully,\u201d he said.<\/p>\n

The TGT (tail gas treatment) unit, which plays a key role in reducing regional emissions, also underwent a major overhaul for the first time in 13 years.<\/p>\n

\u00a0100% of Equipment Overhauled<\/strong><\/p>\n

\n

\u201cThis was the most extensive maintenance project in the refinery\u2019s history,\u201d Sepehri-Rad said. \u201cEvery piece of equipment underwent repair, and 50% of the refinery\u2019s main units received full-scale maintenance after 10 years.\u201d<\/p>\n

The overhaul is expected to raise the refinery\u2019s output by at least 30%. To shorten downtime, the refinery increased work shifts and manpower during the project. \u201cDelays in the overhaul could have affected fuel supply nationwide in 1404,\u201d Sepehri-Rad said.<\/p>\n

He noted that the $60 million spent on the overhaul will soon be recouped through higher production and improved efficiency. \u201cThanks to precise coordination among engineering, procurement, construction, and equipment teams, the project was completed safely and successfully,\u201d he said.<\/p>\n<\/div>\n<\/div>\n
