Properties of propane
Propane is a hydrocarbon (C3H8) and is sometimes referred to as liquified petroleum gas or LPG. Propane is produced from both natural gas processing and crude oil refining, in roughly equal amounts from each source. Propane gas turns into liquid under pressure, so we can easily store and transport this fuel, for example in vessels and cylinders. Propane is nontoxic, colorless and virtually odorless. As with natural gas, an identifying odor is added so the gas can easily be detected.
Propane and the environment
Propane is one of the cleanest burning of all the fossil fuels. Propane fueled vehicles produce 30-90% less carbon monoxide and about 50% fewer toxins and other smog-producing emissions than gasoline. Propane is nontoxic, so it is not harmful to soil, water or air.
Convenient to use
Propane is a clean burning fuel, similar to natural gas. Because propane is stored in portable tanks, it can be used in areas where there is no natural gas network. The installation process is very simple. You need a vessel to hold the propane and a connection to your boiler. Large tanks can be buried underground because propane is a nontoxic, nonpoisonous fuel that doesn't contaminate water or soil. Propane enables many uses. It is an excellent source of energy for heating, cooking, auxiliary heating, pool heating, barbeques, ...
The difference between propane and butane
Butane is like propane and is also and LPG and is also derived from crude oil. Under pressure, the gas turns into a liquid and can easily be stored. Only when you want to use the gas, does it turn into gaseous matter. The biggest difference between butane and propane is the reaction of the two gases at low temperatures. You cannot use butane at freezing temperatures, because its boiling point is set at -0,5°C. Propane's boiling point is -42°C, so you can use propane even when its freezing below zero.
