Cryogenic Liquid Storage Tanks: Understanding the Container Used
Cryogenic liquids, which are substances that boil at temperatures below -150°C, are used in a variety of industries, including healthcare, energy, and transportation. Due to their extremely low temperatures, cryogenic liquids must be stored in specialized containers that can withstand the extreme cold and maintain the liquid’s temperature without evaporating it. Cryogenic liquid storage tanks are the most commonly used containers for storing these liquids. These tanks are designed to keep the cryogenic liquid in its liquid state and minimize evaporation.
Container Types for Cryogenic Liquid Storage Tanks
There are two main types of containers used for cryogenic liquid storage tanks: vacuum insulated tanks and Dewar flasks. Both of these containers are designed to keep the cryogenic liquid at a constant temperature and prevent it from evaporating.
Vacuum Insulated Tanks and Dewar Flasks
Vacuum insulated tanks are the most commonly used containers for storing cryogenic liquids. These tanks are made up of an inner and outer tank separated by a vacuum layer. The vacuum layer acts as an insulator, preventing heat from entering the inner tank and keeping the cryogenic liquid at a constant temperature. The inner tank is made of stainless steel and is designed to withstand the extreme cold temperatures of the cryogenic liquid. The outer tank provides additional insulation and support for the inner tank.
Dewar flasks, also known as Dewar vessels or vacuum flasks, are another type of container used for storing cryogenic liquids. Dewar flasks are made up of a double-walled glass or metal vessel with a vacuum layer in between. The inner wall is coated with a reflective material to minimize heat transfer. Dewar flasks are typically used for smaller quantities of cryogenic liquids and are often used in laboratory settings.
Both vacuum insulated tanks and Dewar flasks are designed to keep the cryogenic liquid at a constant temperature and prevent it from evaporating. However, vacuum insulated tanks are typically used for larger quantities of cryogenic liquids and are often used in industrial settings, while Dewar flasks are typically used for smaller quantities and are often used in laboratory settings.
Conclusion
Cryogenic liquid storage tanks are crucial in industries that use cryogenic liquids. These tanks are designed to keep the liquid at a constant temperature and prevent it from evaporating. Vacuum insulated tanks and Dewar flasks are the two most commonly used containers for cryogenic liquid storage tanks. Vacuum insulated tanks are typically used for larger quantities of cryogenic liquids in industrial settings, while Dewar flasks are typically used for smaller quantities in laboratory settings. Choosing the right container for cryogenic liquid storage is crucial for maintaining the integrity of the liquid and ensuring it remains in its liquid state.
