    I just saw a plaque for a cooking gas company that reads: “Afrox Handigas: Liquefied Petroleum Gas". Now with me being quite ignorant on chemistry, that plaque is pretty funny to me. As far as I know, petroleum is a liquid. So according to the plaque (and my mind), they took a liquid, gasified it and then liquefied it again. :? I know I’m probably wrong in finding it funny, but how does that work?

    LPG is basically the gaseous phase of the hydrocarbons we know as petroleum (petra = greek for stone, oleum....you guessed it). Didn't you notice the flares above offshore drilling platforms? What you see burning is the PG. What a waste! The put it under pressure: LPG

    Oh, ok cool. Is it as cheap and as clean burning as propane or butane? Octane? Dodekatane? . Anyway, the gas you americans use is natural gas = mostly methane?

    LPG is - IIRC - a mix of Propain and Butane. Where the heck is Ophiolite when you need him. He should know.
