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
