SGM(Compression)

IMRAN YOUSAF KHAN

Senior General Manager

As natural gas travels through transportation pipes, its pressure is affected by factors such as elevation changes, distance and friction that cause it to slow and expand. Compressor stations are spaced at regular intervals along the network to re-pressurize gas and re-establishing the correct flow speed to propel it through the pipeline. Compression Department ensures smooth & reliable operation at compressor stations to;

  • Supply natural gas to consumption centers at requisite pressures & flows.
  • Inject low pressure gases from different sources at variable pressures including depleting sources, into transmission network.
  • Accomplish transmission system requirements by ensuring plant reliability and availability.
  • Maintain pipeline integrity and gas quality by scrubbing, straining and filtering incoming gas which passes through the station by removing impurities – such as hydrocarbon particles.

The uninterrupted compression operation maintained by applying;

  • State of the art preventive & predictive maintenance techniques.
  • Monitoring & evaluation of equipment performance.
  • Continuous system improvement & up-gradation through incorporation of latest international technological developments.
  • Planning & development for compression system augmentation & plant expansion as per operational requirements.
  • Well maintained operation of station Fire Gate Valves
