Reverse Osmosis

PRL can meets one third of raw water requirement through reverse osmosis plant.

Water Softening Unit

Unit capacity 150 gallons per minute

Raw water supplied by KDA contains many impurities. This water can produce a hard scale in the inner surface of the boiler tubes during steam generation. These hard scales reduce the heat transfer resulting in more fuel consumption to generate steam. Moreover, the boiler tubes might rupture due to overheating. The removal of these hardness producing salts is the aim of this unit.

Steam Generation Unit

Unit capacity 135,000 lbs per hr

The major source of motive power in the refinery is steam. Steam is generated with the help of boilers. There are three “water in tube” boilers capable of producing 45,000 lbs/hr of super heated steam at 20 kg/cm2 pressure each. The boiler assembly consists of steam drum on the top and the water/ mud drum at the bottom. These drums are connected together by tubes, some of which are extended to form the fire box envelope.

Electricity Generation Unit

Unit capacity 4450 kva

There are number of equipments in the refinery that operate on electricity. PRL’s main source of electricity is KE through bulk supply BS-I & BS-II. These sources are interlinked through auto change over switches. However, in case of a power failure, PRL employs three electricity generation units to provide backup supply to ensure continuous refinery operation. This backup energy is generated through diesel generators.
