Constituents of LPG

Answer 1

Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season---in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN 589

Answer 2

LPG (liquefied petroleum gas) primarily consists of a mixture of propane and butane, along with small amounts of other hydrocarbons such as ethane and pentane. These gases are stored under pressure and used for various purposes, including heating, cooking, and powering vehicles.
