Propane is the most common form of liquefied petroleum gas (LPG) that can
be used as a fuel in areas where no gas mains are installed. A byproduct
of the oil refining process, it is compressed into a liquid for ease of
storage and delivery. In a domestic storage tank, fuel vaporizes in the
upper part of the vessel which can be tapped for use as a cooking and heating
gas. Its pressure is regulated down to a level compatible with the appliances
it runs. In cold climates, the ambient temperature is sometimes too low
for the propane to vaporize fast enough, in which case a heat source, known
as a vaporizer must be used. In its natural form, Propane has no smell
and an odorant is added before distribution, for safety reasons.
The propane industry uses many different types and sizes of tanks, from
30,000 or more gallons at the distributor, to a barbecue
cylinder. Hanson`s ASME propane tanks are built to 250# working pressure.
Under normal circumstances, the vapor pressure at 100ºF is 172 psi.
Hanson Tank manufactures the following types of LPG tanks:
Bulk storage Up to 20,000 gallons
Dispensers (Used to store and transfer liquid propane into smaller
tanks) 250 to 6,000 gallons, horizontal or vertical.
Domestic 124 to 2,000 gallons.
Motor fuel 60 to 250 gallons (Primary or alternate fuel system tanks for autos, trucks, buses.)
Standby fuel 124 to 5,000 gallons. (Back up fuel for remotely located generators, i.e. microwave relay stations)
Underground storage 500 to 5,000 gallons.
DoT tanks MC-331 124 to 3,000 gallons (For the transportation of liquid
propane on a truck or trailer.)
