GAIL India Ltd. successfully pumped the first lot of regasified liquefied natural gas (RLNG) from Kochi to Mangaluru
Process of Regasification of liquefied natural gas (RLNG)
- Regasification is the process of converting LNG at −162 °C (−260 °F) temperature back to natural gas at atmospheric temperature.
- Heat exchangers are used to regasify the LNG after it is removed from the tanks and pressurized between 70-100 bars.
- Generally sea water is used for the regasification process along with high pressure pumps for transferring LNG
Why is natural gas liquified?
- Because transportation and storage of natural gas is cotlier , therefore it is converted to liquid form
- Liquefied natural gas (LNG) is 600 times smaller than natural gas when the latter is in its gaseous form, and it can be easily shipped overseas.
How is LNG produced?
LNG is produced by cooling natural gas below its boiling point, −162 °C (−259 °F), and is stored in double-walled cryogenic containers at or slightly above atmospheric pressure
It can be converted back to its gaseous form by simply raising the temperature.
