Liquefied Natural Gas

 

What is LNG?

LNG - Liquefied Natural Gas Production

LNG is natural gas, purified into almost 100% pure methane and cooled to below its boiling point (-162 degrees centigrade). At this temperature the gas condenses into a liquid taking up 600 times less space. This makes transporting natural gas practical where no pipeline exists, e.g. in remote areas or across oceans.

LNG - Transport and Storage

LNG is transported and stored at relatively low pressures in vacuum insulated steel storage tanks. These tanks work like large thermos flasks - a stainless steel liner holds the LNG, while a second skin formes an insulating vacuum space around the container. This allows the LNG to be stored or transported long distances maintaining its low temperature and liquid state.

Converting LNG back to Natural Gas

Most customers require the LNG to be converted back into a gas so that it can be used in standard natural gas burning boilers, dryers, heaters, engines and generators. This is achieved simply by allowing the LNG to warm up in specialised LNG vapourisers that use warmth from the surrounding air to heat the liquid to it's boiling point.

 

These vapourisers usually require no power or additional heat and resemble large radiators. Once regasified the LNG can be delivered through traditional natural gas pipework.

The Cleanest Fossil Fuel

Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuels. When natural gas is burned, it produces mostly carbon dioxide and water vapour – the same substances emitted when you exhale. Compared with other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted – making natural gas the cleanest burning fossil fuel available.

Why Use LNG?

Lower Your Fuel Costs

Switching to LNG can typically lower your direct fuel costs by up to 30% compared with traditional fuels such as Diesel, resulting in ultrafast paybacks and excellent ROIs for your business, one step ahead of your competition.

Stabilise Your Fuel Pricing

LNG pricing is typically much more stable than traditional oil linked fuel prices such as LPG or Diesel. Allowing you to budget more effectively and offering some protection from rising global oil prices.

Lower Your Carbon (CO2) Emissions

LNG is almost 100% pure methane, the closest commercially available fuel to hydrogen. It is the cleanest burning fossil fuel and can can help reduce your CO2 emissions by up to 30% compared to traditional fuels such as diesel.

Lower Your Particulate Emissions

Particulate emissions from traditional fuels such as diesel, wood, coal and fuel oil, have a major impact on Australia's Air Quality. LNG emits almost zero particulates when properly combusted, helping to improve the local air quality when LNG is used in place of traditional fuels.

Lower Your SOx (Sulphur) Emissions

LNG typically contains no sulphur, hence it emits no Sulphur emissions when combusted. Sulphur emissions (Sulphur dioxide) released into the atmosphere reacts with water vapour and sunlight to form Sulphuric Acid or Acid Rain.

Lower Your NOx (Nitrogen) Emissions

NOx emissions (Nitrous Oxides) released into the atmosphere react with water vapour and sunlight to form Nitric Acid or Acid Rain. LNG can reduce engine NOx emissions by up to 90%.
