Cryogenics
Rapid growth in the current technologies inspires every industry to upgrade its working style. Technical professionals are on continuous research and improvement to increase efficiency. One among these is Cryogenics.
Cryogenics is the study of how to get the low temperatures and how substances behave when they reach such low temperatures. The word ‘Cryogenics‘ is derived from the Greek phrases’ Kryos‘ that means “Frost” and ‘Genic‘ that means “to produce.”
The phrase was first used by Prof. Kamerlingh Onnes of the University of Leiden in the Netherlands in 1894 to explain the art and technology of generating many minimal temperatures. He used the word about the liquefaction of everlasting gases, including oxygen, nitrogen, hydrogen, and helium. Oxygen had been liquefied at -183 C a few years ago (in 1887), and a race turned to melt the other everlasting gases at even lower temperatures.
The temperature at which the cryogenic gases shift from liquids to gas (boiling point) is listed below. Smaller the boiling point, the colder the gas can turn.
The ratio of liquids to gas expansion shows how lots of air is displaced with the aid of a given amount of gas. Even a slight leakage of cryogenic gases can rapidly dislodge all the breathable air in a confined area.
The benefits of cryogenics over various fields are as follows:
Some of the drawbacks of cryogenics are as follows
Cryogenic technology is used in various fields as follows:
Filings of patents on cryogenic technology are eventually rising.
The graph below shows us the Technology Investment Trend over the last 10 Years.
“Air Liquide” holds the maximum number of patents on cryogenic technology, followed by “Air Prod & Chem.” The chart below shows the Top 10 Assignees in cryogenic technology.
The United States seems to have a maximum number of patents filed cryogenic technology compared with other countries.
The graph below provides us with the details of the top 10 countries/regions with the number of patents.
Cryogenics can create a new world where industrial works have to be done at lower temperatures.
