how gases can be transported in pipelines?
How LPG is Transported. LPG exists as either a gas (vapour) or as a liquid, when it is under a modest amount of pressure in gas bottles, cylinders, tanks and larger LPG storage vessels. Given that gaseous LPG has a volume 270x that of liquid LPG, it is almost always transported in its more compact liquid state. LPG (propane) can be transported in a number of ways, including by ship, rail, tanker trucks, intermodal tanks, cylinder trucks, pipelines and local gas reticulation systems.
