With features such as convenience, cleanliness, and safety, city gas has been used extensively by households and industries
City gas is a non-polluting, clean fuel and the best energy that causes no environmental pollution because it discharges almost no pollutants when it burns, since dust, SOx, and NOx are removed during gas liquefaction.
City gas is lighter than air. Therefore, it is safe energy with low possibility of explosion, since it is easily vaporized even when it is leaked and the ignition temperature is high.
City gas is rich in reserves throughout the world, and popular as substitute energy for petroleum because the reserve life index is greater than oil.
Type | LNG | oil | coal |
---|---|---|---|
reserves | about 188.1trillion ㎥ | about 1.7 trillion barrels | about 1.1 trillion tons |
reserve life index | about 48.8 years | about 53.5years | about 139 years |

City gas has higher thermal efficiency than other fuel; it is applied to various business areas such as car, glass, electronics, textile, food, metal, and heat treatment. City gas is economical energy that addresses environmental problems.
City gas does not require any separate means of transportation or storage facility because it is supplied through pipes buried underground. Therefore, city gas can utilize the space very efficiently, and it does not discharge waste and foreign substances.
