You can’t see it or smell it. Touching it would be out of the question since its temperature hovers hundreds of degrees below zero Fahrenheit. While liquefied natural gas (LNG) might not sound familiar, millions of people use the non-toxic and non-corrosive gas everyday. Like natural gas, LNG is around 90 percent methane. It also contains smaller proportions of ethane, propane and butane.
The only differences between LNG and the natural gas that most of us use when heating our homes is the way in which the gas is processed. Like steam becomes water when its temperature drops, natural gas becomes LNG at minus 260 degrees Fahrenheit or minus 160 degrees Celsius. The LNG is then stored at normal atmosphere pressure to maintain its state.
Imagine downsizing a boulder to a grain of sand; the process of changing natural gas to LNG reduces the volume by 600 times. The reduced volume of LNG gives producers the flexibility to transport fuel based on market demands rather than being limited by market distance.
