[0002] Liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing and cooling natural gas or petroleum to liquefy it in an oil refinery. The main components of liquefied petroleum gas are one or two of propane, propylene, butane and butene, and it is also mixed with a small amount of pentane, pentene and trace amounts of sulfide impurities. It is extremely prone to spontaneous combustion. When its content in the air reaches a certain concentration range, it can explode when exposed to open flames. In the production and preparation of liquefied petroleum gas, impurity filter towers are usually used to filter out impurities.
