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 very easy to ignite spontaneously. When its co
ntent in the air reaches a certain co
ncentration range, it can explode when it encounters an open flame.
The main components of the liquefied petroleum gas obtained from the refinery are one or two of propane, propylene, butane, and butene, and it is also doped with a small amount of pentane, pentene and trace sulfide impurities. If you want to further purify the liquefied petroleum gas, you can use the alcohol amine absorption tower to absorb and remove the carbon oxysulfide, and finally wash the excess sulfide with alkali.
