Natural Gas

  • Natural gas is a colourless, odourless mixture of gases made up mostly of methane (CH4).
  • Other gases that can form part of natural gas include small amounts of ethane (C2H6), propane (C3H8) and butane (C4H10).
  • Methane burns relatively cleanly to produce heat energy and the by-products of water and carbon dioxide. Inefficiencies in burning can produce small amounts of pollutants such as nitrogen oxides.
  • Natural gas is lighter than air. So if it leaks from a pipe or appliance, it won’t sink and form dangerous pools of explosive gas but will disperse in the air.
  • In certain concentrations, natural gas can be explosive, so it should always be treated with care.
  • For safety reasons, an odour is added to the gas so that a person with a normal sense of smell can easily detect leakages. The odour additive is Methyl Mercaptan (Methanethiol: CH3SH) which is a byproduct of decomposition that smells like rotten egg due to the presence of sulphur. Humans can detect the strong smell of methyl mercaptan in the air at extremely low concentrations, starting at around 1.6 parts per billion. This makes it an ideal additive to odourless gases for safety detection.

Domestic Use

Natural gas dispensed from a simple stovetop can generate temperatures in excess of 1100 °C making it a powerful domestic cooking and heating fuel. In urban and suburban Sydney it is generally supplied through pipes to homes, where it is used for many purposes including stove range tops and ovens, clothes dryers, stand alone heaters, central heating and water heaters/boilers. Heaters in homes and other buildings may include boilers, furnaces, and water heaters.

Liquified petroleum gas (LPG) and to a lesser extent compressed natural gas (CNG) are more commonly used in rural homes without connections to piped-in public utility services, camping, barbecues and portable grills, because they can be stored conveniently in a steel pressure vessel. Gas bottles and cylinders can be safely transported by road vehicle and are commonly sold at petrol stations, camping stores and gas retailers. They are usually stored as a compact liquid under moderate pressure and burned as a dry gaseous vapour. (It expands to approximately 270 times its liquid volume when reverting to vapour).
