Attock Refinery Limited (ARL) has announced the successful resumption of operations at its main crude distillation unit (HBU-1), marking a significant development for the country’s refining sector. The disclosure was made through a material information notice submitted to the Pakistan Stock Exchange (PSX) on May 4, 2026.
According to the company, the refinery’s primary crude distillation unit, which has a processing capacity of 32,400 barrels per stream day (BPSD), has restarted operations following the normalization of crude oil receipts and the restoration of product dispatches through oil tankers. The unit had previously faced operational disruptions due to challenges in the supply and distribution chain.
The latest development follows an earlier communication issued by the company on April 23, 2026, regarding the operational status of the refinery. With crude supply logistics returning to normal, ARL has been able to bring its key processing facility back online, ensuring continuity in refining activities and supporting the domestic petroleum supply chain.
The resumption of HBU-1 operations is expected to strengthen refinery throughput and contribute to the availability of refined petroleum products in the market. As one of Pakistan’s major refining companies, Attock Refinery plays an important role in meeting the country’s energy requirements and maintaining fuel supply stability.
The company has requested the PSX to disseminate the information to market participants in accordance with applicable regulatory requirements governing material disclosures.
