3-Oxygen & Nitrogen

Pakistan Steel has it's own Oxygen Plant, manufactured by L'Air Liquide of France. The plant is designed and operated to a capacity to fulfill all our production needs. The plant comprises two identical air separation units in which oxygen and nitrogen are distilled from the atmosphere. The main consumer of oxygen is the Steel Making Plant where oxygen is blown into the convertors in order to convert molten iron into steel. Oxygen is also supplied to the Central Maintenance department where it used in welding and cutting processes.

The gaseous Nitrogen produced is mainly used as a shielding & purging gas at the Cold Rolling Mill in the annealing & galvanizing units. Nitrogen is also used in the hydraulic systems of the Cold Rolling and Hot Strip Mills and as an inert gas at the Coke Dry Quenching Plant. In addition both gases are also supplied in cylinders to facilitate the work where pipeline network is not available.

In addition both gases are also supplied in cylinders to facilitate the work where pipeline network is not available and liquid oxygen is also made for external sales, subject to availabilty.

	Oxygen	Nitrogen
Output (cubic meters/hour):	15200	9000
Purity:	99.5%	15ppm
Pressure (bar):	0.15	0.80

6-Coal Tar

Specifications

Density at 20°C:	1.1930 (Typical)
Moisture:	5% max
Ash:	0.3% max
Flash Point According to Pensky Martens (open cup):	139°C

Coal tar is a by-product of the Coke Oven and By-product plant during the manufacture of metallurgical coke. Coke oven gas of 80 - 82°C is cooled in tubular gas coolers equipped with horizontal tubes each with a 3000 square meter cooling surface. Coke oven gas after cooling in the coolers is delivered for purification from the tar traces into electrostatic precipitators located on the suction side of the coke oven gas blowers. The coal tar is sent to tghe tar settling tanks for separation from water, then it flows to the tank for coal tar from where it is pumped to the storage tanks.
