 LPG vs LNG – A Clear Comparison

This informative image contrasts LPG (Liquefied Petroleum Gas) and LNG (Liquefied Natural Gas) across six key areas:

A. Composition:

1. LPG: Mix of propane (C₃H₈) and butane (C₄H₁₀).

2. LNG: Mainly methane (CH₄) with small amounts of ethane and propane.

B. Storage & Temperature:

1. LPG: Stored at ambient temperature under moderate pressure (5–10 bar).

2. LNG: Stored at extremely low temperatures (-162°C) in cryogenic tanks at atmospheric pressure.

C. Density & Energy Content:

1. LPG: Denser (0.55–0.58 kg/L), higher energy per liter.

2. LNG: Lighter (0.45 kg/L), higher energy per kilogram.

D. Applications:

1. LPG: Cooking, heating, autogas, industrial uses.

2. LNG: Power generation, industrial fuel, marine fuel, and diesel alternative.

E. Safety Considerations:

1. LPG: Heavier than air, accumulates in low areas (explosion risk), easier to handle than LNG.

2. LNG: Lighter than air, disperses quickly, needs cryogenic handling to avoid burns.

F. Source & Production:

1. LPG: Byproduct of natural gas processing and oil refining.

2. LNG: Extracted from natural gas fields, purified, and liquefied.

G. Key Takeaway:

1. LNG is growing in industrial and transport use due to lower carbon footprint, but LPG remains vital for household and light industrial needs. Each has unique storage, safety, and energy characteristics.
