Premise Liquefied petroleum gas is derived from oil gas, natural gas, the gas production of refinery and petrochemicals. The main components are dimethylmethane, propylene, butane, butylene and such low class hydrocarbon. It's a gas with achromaticity and transparence; LPG is hardly dissolved in water, but dissolved in ethanol and aether, it can dissolve gas production, propagation oil and caoutchouc.
