What is a common tank type used to store liquefied natural gas (LNG)?

The type of tank commonly used to store liquefied natural gas (LNG) is specifically designed for that purpose, which is why the term "Liquefied Natural Gas tank" is apt. These tanks are constructed to handle the low temperatures that LNG is maintained at, typically around -162 degrees Celsius (-260 degrees Fahrenheit), and are designed to withstand high pressure.

Liquefied Natural Gas tanks feature insulated and double-walled designs to prevent heat influx and protect against potential leakage. Additionally, these tanks facilitate the safe management of LNG, ensuring that the risk associated with storing such a cryogenic fluid is minimized. Their specific design ensures they can accommodate the unique conditions required for liquefied gas storage, making them distinct from other tank types listed.

In contrast, fixed-roof tanks, horizontal tanks, and pressure tanks are more generalized types of storage tanks that can store a variety of products but are not specifically tailored for LNG storage. While each has its applications—such as atmospheric storage or pressurized storage—they do not possess the specialized features necessary for the safe storage of liquefied natural gas.
