Storage of Liquids
Atmospheric Tanks - designed to operate at pressures from atmospheric through 3.45 kPa (0.5psig) - used for the storage of fuel for transportation and power generation.
Shop- Fabricated Storage Tanks - constructed at a tank manufacturer's plant and transported to a facility for installation.
- Tanks 190m^3 (50 000 gal) and under
Aboveground Storage Tanks- ability to visually monitor- avoid perceived risk and myriad regulations
• field – erected• shop-fabricated – store flammable or combustible liquids
Underground Tank Storage-liquid to be stored must be tolerate water, brine and other contaminants.- stored natural gas liquids, LPGs, crude oil, and refined petroleum products. Pressure Tanks - vertical cylindrical tanks constructed with domed or coned roofs. - operate at pressures above several hundred Pascal.
Storage of Gas
Gas holder - holds either liquid-seal or dry-seal types
Cavern storage - stored natural gas, sometimes hydrogen and air- Contain brine and other contaminants
