What is LPG?
LPG stands for liquefied petroleum gas. It is commonly used for cooking and for heating water. It is a clean-burning, nonpoisonous, dependable and high-performance fuel stored and transported in containers as a liquid, but is generally drawn out and used as a gas.
What is the composition of LPG?
LPG occurs naturally in crude oil and natural gas production fields, and is also produced during the oil refining process. It is a mixture of light gaseous hydrocarbons (propane, butane), which are gaseous at a normal ambient temperature and atmospheric pressure, but become liquid through the application of moderate pressure.
At normal temperatures and pressures, LPG will evaporate, so it is supplied in pressurized steel cylinders. To allow for thermal expansion, these cylinders are typically filled to between 80 and 85 percent of their capacity.
