A Possible White Cloud

As part of some maintenance we are doing at our Whitehorse LNG site, people travelling along the site over the lunch hour might notice a white cloud. The cloud, if it is visible, will NOT be LNG. It will instead be liquid nitrogen. Liquid nitrogen is a harmless gas (the air we breathe is made up of 78 percent nitrogen) that does not create any GHG emissions, is not flammable, and is even colder than LNG; it boils at -196°C compared to -162°C for LNG. We use it to cool our tanks so they can be ready to receive liquefied natural gas.

As the liquid nitrogen is released, you may also hear a whistling noise. This is normal and perfectly safe. We want to emphasize that this will be harmless nitrogen and not liquefied natural gas.
