In this calculation weâll use an ethane heat content of 66,500 BTU per gallon. The top boxes in Figure #1 show the conversion of the ethane price per gallon to dollars per MMbtu. So if the price of ethane is 22 cents, divide by 66,500 and multiply by 1,000,000 to yield an equivalent gas price of $3.31/MMbtu.
Ethane is a hydrocarbon gas made from petroleum. It is the second (first is methane) in a series of simple hydrocarbon petrochemical compounds in a family of related compounds named âAlkanesâ, all of which have the feature of containing only single bonds between carbon atoms. The chemical formula for ethane gas is C 2 H 6. 2  Ethane is a hydrocarbon that exists in nature as an odorless and colorless gas at standard temperature and pressure. 3  It is a stable compound and shows resistance to reactivity. 4  It has a molar mass of 30.07 grams per mole (g/mol).
