Plant & Operational Overview

Pakistan Steel has its own Oxygen Plant, manufactured by L'Air Liquide of France. Designed and operated to fulfill all internal production needs, the plant comprises two identical air separation units where oxygen and nitrogen are distilled directly from the atmosphere.

The primary consumer of oxygen is the Steel Making Plant, where it is blown into converters to transform molten iron into steel. Oxygen is also supplied to the Central Maintenance Department for welding and cutting processes.

Gaseous nitrogen is mainly utilized as a shielding and purging gas at the Cold Rolling Mill in annealing and galvanizing units, in hydraulic systems across the Cold Rolling and Hot Strip Mills, and as an inert gas at the Coke Dry Quenching Plant. Both gases are supplied via pipeline networks and in cylinders where pipelines are unavailable. Liquid oxygen is also manufactured for external sales subject to availability.
