Frequently Asked Questions
No, natural gas is primarily methane. Ethane is a separate, heavier hydrocarbon often found mixed with natural gas.
Pure ethane is odorless. The 'gas smell' associated with domestic gas is from an added odorant for safety.
Ethane (C₂H₆) is a simple alkane gas. Ethanol (C₂H₆O) is an alcohol liquid, commonly found in alcoholic drinks and used as a fuel additive.
Like many flammable gases, it is hazardous if not handled properly due to fire and explosion risk. It is not toxic but can displace oxygen in confined spaces.
