What is the Purpose of Storage Cavern MIT?

Storage caverns are often cavities that are dug out of great salt deposits through a technique called solution mining. Since salt caverns are essentially the storage caverns that are high on demand for storage of hydrocarbon, it is crucial that not only are clients able to meet their demands, but the environmental impact of storing petroleum on a large scale can be greatly reduced.

Storage caverns are man-made cavities inside salt deposits. The reason petroleum companies build storage caverns in such locations is because salt caverns are very secure as storage spaces. Another thing why they favor the use of salt caverns is because it is very cheap and economical to both create and maintain. The problem with storage caverns inside salt mines is that the spaces created is not always the same as the irregular shape that have been pre-formed during solution mining creates dimensional difference between different cavities made. And even if the salt caverns are manmade, it does not always mean they can replicate their most perfect cavern each time.

When salt caverns are created, they need to undergo a series of tests to ensure that the cavities are able to carry and withstand different tests and measures of the cavities structural integrity. One of the most popular tests being performed on salt storage caverns is mechanical integrity test. This storage cavern MIT is basically a test that measures the tightness of the cavern storage wells. It is performed as an integrity test, a casing test, and as a cavern test. Passing different testing routines from a group of expert panels is reassurance that the storage cavern has met all the necessary standards and is very safe to both use and operate.

Underground storage caverns like salt caverns will always be the safest way to store huge volumes of hydrocarbons. However, even if salt cavern storage is considered to be one of the safest methods of storing hydrocarbons, any lapse within the different testing being made will end up catastrophically. But since hydrocarbons require oxygen in order to combust, the lack of oxygen within the underground storage means that lighting even a matchstick will prove to be quite difficult. The hundreds of meters of space between hydrocarbons and oxygen above ground stand as the perfect protection against the combusting of the hydrocarbons.

When it comes to storage capacity and reliability, salt caverns that are buried hundreds of meters below ground are still by far the safest with very little environmental input and impact. Any poor design or structural issue within the salt cavern may result in catastrophic failure that leads to the leakage of both environmental and industrial waste. This is the very reason why very distinguished engineers and structural design architects man the safety panel that examines new and repurposed storage caverns.
