1. Natural Gas Mixture of methane, propane, ethane, cardbon dioxide, butane,
hydrogen, nitro- gen. Gas cna be transported in gas or liquid state.
Weight of gas is 0.6 air is 1.0. Propane is heavier than air +1.0. Gas
burns a clean blue flame.
2. Mercaptan Odorant (sulfur) added to gas for smell detection of leaks. New steel
pipe may contribute to odor fade because of small rust deposits in
the pipe.
