Cryogens are the kind of gases which can undergo condensation at very low temperatures to become liquids and later solidify into solids. All cryogenic liquids exist in gaseous forms at room temperature. The reason behind changing the gases to liquids or solids is to make transportation and storage easier. This does happen because a huge amount of the gas normally turns into a very small amount of liquid when it undergoes condensation. This is what Cryogenic gases are all about.
When the gas is condense, it reduces in volume by 600 to 900 times of the cryogenic liquid. The implication here is that a single liter of the liquid can form 900 liters of gas. It is this convenience that makes it necessary to condense the gas for easier storage. The condensed gas now be transported and stored easily without needing too much space.
In order to store and transport these products, specially designed tanks are usually used. These tanks usually vary in size and capacity. They are designed in a way that they can withstand a very high level of pressure. They are also able to withstand rapid changes in pressure and extreme differences in temperature. As they withstand the changes in pressure and temperature differences, they must be able to keep contents at a constant temperature.
High levels of standards are adhered to during the production process of these tanks. Strict quality assurance is also adhered to all the time during the manufacturing process. There are several stages in the process of production that are used to test the tanks vigorously. It is also mandatory for every tank to undergo specific sets of test before being put to use. If the tanks fail the tests, they has to be recycled or remade.
The quality and superiority of tanks are normally measured depending on how long the cryogen can be stored in them without problems. There is low loss of the product if the tank is of high quality because it can keep the cryogen for a long period of time. A quality tank should keep the product for a minimum of 25 days but up to several months. This is essential because it is very expensive to keep changing the storage of the gase often.
As part of safety, tanks are usually designed with pressure release valves. As such, when pressure inside the tanks rises beyond a given level, the valve opens and releases the gas into the air. Usually there are sensors that detect such occurrences. It is important to know if there is a leakage in a tank so that proper measures can be taken to contain the situation.
There are several hazards that are associated with cryogens. In one case, they can cause asphyxiation. Asphyxiation occurs when there is a lack of sufficient oxygen in the atmosphere or a body organ. This may be caused by the presence of some of the denser gasses such as nitrogen, which displace oxygen since it is lighter. This only happens when the denser gas exists in very large volumes.
The presence of excess oxygen on the other hand usually leads to excessive combustion. This may result in catastrophic fires because oxygen gas supports burning. Frostbite, over pressurization, cold burns, and hypothermia among others are the additional effects of cryogens.
