The term cryogenic is usually used to refer to something that produces or is related to very low temperatures. As such, the term cryogenics refer to gases that have been subjected to very low temperatures to form liquids or solids. The boiling point of these gasses is usually below -150 degrees centigrade. Nitrous oxide and carbon dioxide usually have higher boiling points but are also classified under cryogenic substances. Here are facts regarding Cryogenic gases.
Cryogenic substances occur as gases at room temperature and pressure. The process of liquefying them involves cooling them below room temperature and then subjecting them to high pressure. There are different circumstances under which cryogens become liquids. Nevertheless, there are two characteristics that cut across all cryogens. To begin with, they are extremely cold. Secondly, minute amounts of the liquid evaporate to form huge amounts of gas.
The released gas or vapor is normally extremely cold. The moisture around the gas is condensed by the low temperatures. As such, this leads to visible mist being formed. Should cryogens be stored in poorly insulated tanks, they cause condensation of the surrounding air, forming a liquid mixture of air.
There are risks associated with working with cryogens. For this reason, any person that handles cryogens needs to understand all the risks involved with the job clearly. In addition, they are supposed to implement various precautions in order to prevent and overcome accidents in case they occur. There are standards that have been formulated and are in use. These standards are meant to ensure safety of people who work with these substances.
Cryogens exist in three major groups, that is, inert gasses, flammable gasses, and oxygen. Each cryogen has its own unique properties, but they all fall in the three groups named above. Inert gasses do not undergo any form of chemical reaction to any great extent. As such, they do not burn and they do not support combustion. Examples of gases that can be classified under this group are krypton, neon, argon, helium, and nitrogen.
As the name suggests, flammable gasses are flammable and burn in the presence of air. Liquefied gasses, hydrogen, and methane are some of the gasses in this groud. Because of the ability of oxygen to support combustion, it is usually categorized in its own category. In the presence of oxygen, most substances that are generally incombustible normally burn. When discussing cryogens, this necessitates considering oxygen separately.
Given the dangers that are associated with cryogens, it is important that they are stored carefully. Storage is usually done in thermally insulated containers. The containers used are usually designed in a way that they can withstand extreme temperature differences. They can also withstand rapid changes in temperature.
There exist a number of medical conditions that the body may suffer from as a result of getting in contact with cryogens. For example, extremely cold gases are able to burn the skin the same way that heat does. Being exposed to extremely cold substances normally leads to frostbites. This makes the skin to have a waxy-yellow look. Individuals experience a lot of pain when the area that has been in contact with cryogens begins to thaw.
