The storage state of most industrial gases varies depending on the type of gas and its intended use. Compressed gases, such as oxygen, nitrogen, and argon, are commonly stored in high-pressure cylinders, which are designed to safely contain these gases under significant pressure. Liquefied gases, including liquid nitrogen, liquid oxygen, and liquefied petroleum gas (LPG), are stored either under high pressure or at low temperatures to maintain their liquid state.

• Compressed Gas: Stored in high-pressure cylinders.

• Liquefied Gas: Stored as a liquid under high pressure or low temperature.

• Cryogenic Liquid: Stored at extremely low temperatures to maintain a liquid state.

• Dissolved Gas: Dissolved in a solvent under pressure.

• Compressed Natural Gas (CNG): Natural gas stored at high pressure.

• Liquefied Natural Gas (LNG): Natural gas cooled to a liquid state at very low temperatures.

• Adsorbed Gas: Stored in a solid material at relatively low pressure.

• Chemical Storage: Stored in a chemical compound that releases the gas upon decomposition.

• Bulk Storage: Large volumes stored in tanks or spheres.

• Portable Storage: Small, portable cylinders for ease of transport and use.

• Pipeline Distribution: Stored and transported through pipelines.
