What is Gas Tank
A gas tank, or fuel tank, stores and transports gases or liquid fuels. Usually, when people say “gas tank,” they mean the one in vehicles that holds gasoline, diesel, or other liquid fuels. But the term also covers tanks that store compressed gases like natural gas, propane, or industrial gases.
How does a Gas Tank work?
Compressed Gas Tanks
These tanks store compressed gases like compressed air and natural gas. Their working principle follows Boyle’s law: at a fixed temperature, a gas’s pressure and volume are inversely related. We compress the gas into the tank, squeezing it to increase the pressure.
Liquefied Petroleum Gas (LPG) Tanks
LPG tanks hold liquefied petroleum gas. We usually liquefy this gas either by cooling it down or applying high pressure. They work by storing the gas in its liquefied form, which we can achieve through pressurization or refrigeration.
Natural Gas Tanks
These tanks store natural gas, either as compressed natural gas (CNG) or liquefied natural gas (LNG). CNG tanks compress the gas under high pressure, while LNG tanks keep the natural gas in liquid form at extremely low temperatures.
Industrial Gas Tanks
Industrial gas tanks store gases used in industries, such as oxygen, nitrogen, and argon. Manufacturers design these tanks to hold gas at high pressure, making it easier to transport and use.
Fuel Cell Gas Supply System Tanks
These tanks store compressed hydrogen for fuel cells. We compress the hydrogen under high pressure so it can supply enough pressure when the fuel cell needs it.
Breathing Air Tanks
Breathing air tanks store air for diving or emergencies. We compress the air to a high – pressure state for storage. When in use, a pressure – reducing valve gradually releases the gas to a normal breathing pressure.
