LPG is the abbreviation of liquefied petroleum gas, which is a mixture of propane and butane, usually accompanied by a small amount of propylene and butene. Usually, ethanethiol with strong smell is added, so that the leakage of liquefied petroleum gas can be easily found. Liquefied petroleum gas (LPG) is produced when crude oil is refined, or gas emitted during the exploitation of oil or natural gas. Liquefied petroleum gas is often mistaken for propane.
Introduction of liquefied gas
In fact, liquefied petroleum gas (LPG) is a mixture of petroleum and natural gas under appropriate pressure, which exists in liquid state at room temperature. In the United States and Canada, the mixture of these two substances is usually considered to be mainly composed of propane, while in many European countries, the propane content in liquefied petroleum gas is only 50% or less.
Liquefied petroleum gas has been used as fuel for light vehicles for many years, and it can also be stored in storage tanks to provide fuel for automobiles. Liquefied petroleum gas is a kind of petroleum products. It is a colorless and volatile gas produced in oil and gas fields, refineries and ethylene plants. Mainly used in automobile, city gas, nonferrous metal smelting and metal cutting.
LPG is the most mature fuel used in China automobile alternative energy technology. It is predicted that in the future, most of the liquefied petroleum gas in urban civil gas in China will be replaced by natural gas, and the output of liquefied petroleum gas as a by-product of petroleum refining will increase with the increase of total petroleum refining. By then, there will be overcapacity of liquefied petroleum gas, and its application in automobiles will not only bring remarkable economic benefits, but also reduce greenhouse gas emissions.
