Introduction to LPG

Liquefied petroleum gas is a colorless volatile liquid obtained by liquefying natural gas or petroleum under pressure and cooling in an oil refinery. It is highly prone to spontaneous combustion. When its content in the air reaches a certain concentration range, it can explode when it encounters an open flame.
The liquefied petroleum gas obtained through the refinery is mainly composed of one or two of propane, propylene, butane, and butene, and it is also doped with a small amount of pentane, pentene, and a small amount of sulfide impurities. If the liquefied petroleum gas is to be further purified, an alcohol amine absorption tower can be used to absorb and remove the carbon dioxide sulfide, and finally the excess sulfide can be washed away with alkali.
The liquefied gas obtained via natural gas contains substantially no olefins. Liquefied petroleum gas is mainly composed of hydrocarbons, and its main components are propane, butane and other alkanes. Of course, there are also standards for the composition of liquefied petroleum gas. Not all substances in this composition can be called liquefied petroleum gas. Only the gas composition of propane and butane with a percentage ratio of more than 60% can be called liquefied petroleum gas. called liquefied petroleum gas. Of course, not all standards are the same. In foreign countries, they are more particular about the regulations on liquefied petroleum gas. Its definition needs to adjust the composition of propane and butane according to seasonal changes. However, my country's liquefied petroleum gas is mainly used for household use, so there is not so much attention. If it is to be applied to industry, we need to formulate a more detailed ratio of the composition of liquefied petroleum gas Rule out .
Using liquefied petroleum gas as fuel, because of its high calorific value, no smoke, no carbon residue, easy operation and use, has widely entered the field of people's lives. In addition, liquefied petroleum gas is also used for cutting metals, baking agricultural products and roasting industrial kilns, etc.
