Does LPG comes from methane gas?

Answer 1

Light hydrocarbons (methane, ethane, propane, butane, etc.) are generally gases at normal temperatures and pressures. With the exception of methane they can be easily turned into liquids when cooled or stored under pressure. All these gases are present in natural gas or the gas fraction of petroleum oils. They are also created during the fractionation, cracking and reforming processes at refineries.

Once liquefied ethane, propane and butane are called. LPGs (Liquefied Petroleum Gases)

Methane is not generally considered an LPG although it can be liquefied at high pressures and low temperatures. All the gases come from the same source
