LPG - Liquefied Petroleum Gas

LPG (Liquefied Petroleum Gas) is a hydrocarbon mixture consisting of propane, propylene, isobutane, n-butane, and butylene. It is gaseous under normal atmospheric conditions but liquefied by cooling and/or compression. Commonly used as an industrial fuel for domestic, commercial, and chemical applications.

LPG - Liquefied Petroleum Gas

LPG (Liquefied Petroleum Gas) is a hydrocarbon mixture in either liquid or gaseous state where the main components consist of:

Propane - C₃H₈
Propylene (Propene) - C₃H₆
Isobutane - C₄H₁₀
n-Butane - C₄H₁₀
Butylene (Butene) - C₄H₈

Liquefied Petroleum Gas (LPG) is gaseous under normal atmospheric conditions, but liquefied by cooling and/or compression.
