Liquefied Natural Gas (LNG) vs. Liquefied Petroleum (LPG) Gas: Differences and Main Applications.
In the energy sector both LNG and LPG play crucial roles, but do you know the main differences between them?
A. Formation :
1 Liquefied Natural Gas: Essentially Methane (CH4) with ethane and propane effects.
2. Liquefied Petroleum Gas: A mixture of propane (C3H8) and biothane (C4H10)
B. Storage and temperature :
1. Liquefied Natural Gas: It is stored at -162°C (-260°F) in refrigerated tanks at atmospheric pressure.
2. Liquefied Petroleum Gas: is stored at ambient temperature under moderate pressure (5-10 bar) in compressed
tanks.
C. Density and content of energy:
1. Liquefied Natural Gas: lighter in weight (0.45 kg/l) but has higher power per kilogram.
2. Liquefied Petroleum Gas: more concentrated (0.55-0.58 kg/l) with higher power per liter .
D. applications :
1. Liquefied Natural Gas:
a. Generation Energy
b. Industrial Fuel |
c. Marine Fuel
d. Diesel Alternative in Transport.
2. Liquid Petroleum Gas:
a. Cooking
b. Heating
c. Autogas
d. Industrial Operations.
E. Safety Considerations:
1. Liquefied Natural Gas: Lighter than air, dissipates quickly, reducing explosion risks
2. Liquefied Petroleum gas: heavier than air, can accumulate in low-lying areas, increasing the risk of explosion.
F. Sources and Production:
1. Liquid Natural Gas:
It is extracted from the natural gas fields and cooled into a liquid form.
2. Liquid Petroleum Gas: a secondary product for natural gas treatment and crude oil refinement.
F. Liquefied Natural gas is an emerging fuel for the industrial and transportation sectors due to its low carbon footprint, while Liquefied Petroleum Gas remains an important source of energy for domestic and commercial heating.
