LPG Transmission

GAIL is the first company in India to own and operate pipelines for LPG transmission. It has 2033 km LPG pipeline network 1,410 km of which connects the western and northern parts of India and 618 km of networks is in the southern part of the country connecting Eastern Coast. GAIL has dedicated LPG pipelines from GPU, Gandhar and GPU Vijaipur to OMC Bottling plants . The LPG transmission system has a capacity to transport 3.83 MMTPA of LPG.

LPG Applications

  • Domestic: For use in household
  • Commercial: For use in hotels, bakeries, canteens, etc
  • Auto: For use as fuel in automobiles
  • Industrial: For use in production process

Characteristics of GAIL LPG

  • Processed from Natural Gas
  • Has a high vapour pressure vis-a vis Refinery LPG
  • Vapourises at atmospheric temperature and pressure
  • Clean fuel with almost nil unsaturated compounds
  • Has a higher calorific value than Refinery's LPG and hence gives more value for money
  • Its homogeneous composition results in more efficient combustion
  • The air fuel ratio need not be changed with every batch
  • No Impurities like sulphur, carbon dioxide, traces of oxides of nitrogen. Hence having least corrosion compounds
  • Has nil moisture content
