The same is oxygen, what is the difference between the industrial oxygen in the medical oxygen and VPSA oxygen?
Medical oxygen, as a type of medicine, requires more than 99.5 percent of the purity and is mainly used for breathing and medical care. Medical oxygen is a large air separation device to separate the oxygen in the air, and then transforms the gas oxygen into liquid oxygen by low temperature at minus 183 ° C, removes the impurities in oxygen, and pour the liquid oxygen to the oxygen cylinder as much as possible. In order to make the medical oxygen suitable for the body’s breathing requirements, in addition to removing the harmful gases to the human body during the production and filling process, the main thing is to remove the moisture in oxygen. Therefore, the national pharmaceutical regulatory department requires production and obtains permit for operating medical oxygen. Industrial oxygen use is mainly used for industrial production and product processing. The quality requirements are relatively low, and there are more impurities. At the same time, there are also harmful impurities such as carbon monoxide and carbon dioxide in industrial oxygen. Once the patient is inhaled excessively, cough and scabs will occur, causing or aggravating the weight of the respiratory system.
It can be seen that the industrial oxygen in medical oxygen and VPSA oxygers cannot be mixed.
