Town gas sites

Town gas is a combustible gas and poses the risk of accidents if leaks occur. Describes the process from LNG raw material receiving to gas consumer, with illustrations of the various gas detectors and calorimeters used.

Overview of town gas processes

LNG tank, vaporizer, heat regulator

Natural gas is stored in LNG tanks by cooling to the ultra-low-temperature of -162 °C to liquefy into LNG (liquefied natural gas).
The vaporizer is a plant that returns the LNG to natural gas.


Take precautions to prevent natural gas leaks. It is essential to detect minute leaks in the early stages. When LNG leaks, it vaporizes and expands in volume approximately 600-fold.
