What are the main characteristics of LP Gas?
Butane boils at around zero degrees Centigrade and Propane boils at minus 42 degrees Centigrade. One of the main characteristics of LP Gas is the fact that it is portable. In liquid form the product can be easily transported. Although LP Gas is stored as a liquid it is generally used in a vapour (or gaseous) phase. One unit of liquid LP Gas will generate 250 units of vapour. LP Gas vapour is heavier than air. Any leak will fall to the ground and seek out drains, gullies and waterways. In liquid form LP Gas has a density of around half that of water which means it will float on rivers and waterways if the ambient temperature is low enough. These are important characteristics when designing LP Gas storage and distribution facilities. LP Gas vapour is invisible and has no natural odour and so a stenching agent is added to the product to enable any leaks to be detected by smell. The gas burns in a narrow range of between 2% and 10% of LP Gas in air. These are called the flammable limits. T
