What is the difference between natural gas and propane gas?

“Propane is produced as a by-product of two other processes, natural gas processing and petroleum refining. The processing of natural gas involves removal of butane, propane, and large amounts of ethane from the raw gas, in order to prevent condensation of these volatiles in natural gas pipelines. Additionally, oil refineries produce some propane as a by-product of cracking petroleum into gasoline or heating oil.”

Natural gas is a combination of several different chemicals one of which is propane.

Propane is just pure propane.

Here’s the whole enchilda.

Propane gas is product of two other processes and natural gas has different chemicals.

I like @Lightlyseared‘s definition. I was further thinking that natural gas is the stuff that comes to your house in a pipe and propane comes in big gas bottles/canisters. But willing to be corrected

Natural gas is mixture of methane and other gases, propane is actually a by product of both petroleum refining and natural gas processing.

Thanks, @JamesWilsn, and welcome to Fluther. Ride the wave for a bit and I think you’ll enjoy it.
