LPG Mix Reference
LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG/air mixing ratios average 60/40, though this is widely variable based on the gases making up the LPG.
Few examples of Natural Gas Standard are given below
| Methane 0.5% + Ethane 0.5% + Ethylene 0.5% + Propane 30% + Propylene 4% + Propadience 0.5% + n-butane 15% + 1-butene 5% + cis-2-butene 0.5% + trans-2-butene 0.75% + 1,2-butadience 1.5% + 1,3-butadience 1% + isobutylene 4% + n-pentane 1.25% + iso-pentane 2% + iso-Butane Balance | CGM16363110 |
