Cryogenic liquids

02 FEB, 2016

Natural gas in its natural state, at room temperature, is in gaseous state, in order to increase the storage capacity of this product, it proceeds to liquefaction, and natural gas remains in the liquid state at temperatures of -160 ° C due to its "cold" nature. The cryogenic gases present four hazardous characteristics as follows:

 

Health risks: cryogenic gases, due to low temperature, can cause severe burns to the tissue when in contact with its liquid state or vapor.

 

Effects on other materials: cryogenic gases can condense or solidify other gases. The solidification temperature of water is 0 ° C at atmospheric pressure. This means that the water present in the air (humidity) may freeze in case of discharging a cryogenic substance. If this occurs next, for example, a valve (which may be a tank itself), it will present difficult to perform maneuvers. Operation with this type of gases must be performed by individuals with adequate training and experience.
