Attock Refinery Limited


Glorious Past ….. Promising Future

Attock Refinery Limited (ARL) set up in 1922, with two small stills of 2500 barrels per day (bpd) is the pacesetter of Pakistan’s petroleum refining industry. In late thirties and early forties the refining capacity was enhanced to 10,000 bpd. In 1981 with addition of two distillation units the capacity came to 35,000 bpd. In 1999 it was further up-graded with the addition of a Heavy Crude Unit, a Reformer unit and a Captive Power Plant with the capability to process from the lightest to the heaviest (10 – 65 API) crudes increasing the capacity to 43,000 bpd.

In 2016, ARL completed a major expansion and up-gradation project comprising Diesel Hydrodesulphurization (DHDS) Unit (to reduce sulphur contents in High Speed Diesel to meet Euro II specifications), Preflash Unit (to enhance refining capacity by 10,400 bpd), Isomerization Unit (to enhance production of Premium Motor Gasoline by about 70%) and expansion of existing Captive Power Plant by 18MW. The refining capacity now stands at 53,400 bpd with improved specifications of products. The Company continues to operate at about 100% capacity inspite of many hurdles and challenges through induction of advanced technologies, improvement in skill index of its human resources and excelling in standards of health, safety and environment.

Technical studies are underway for installation of Continuous Catalyst Regeneration (CCR) unit for further improvement of gasoline specifications and installation of other process units for deep conversion to enhance volume of value added products. Further expansion / upgradation of the refinery will depend on sustainable availability of local crude, demand supply situation of products, future product specifications and investment friendly Refining Policy.
