How do you get Argon or E938?

The E938 additive, also known as argon, is obtained through an air distillation process. Here I explain how it is carried out

Obtaining air The first step to obtain the E938 additive is to collect large quantities of atmospheric air. Air is composed primarily of nitrogen (about 78%), oxygen (about 21%), and small amounts of other gases.

Compression Next, the air undergoes a compression process in which its volume is reduced. This is done through special equipment called compressors.

Cooling Compressed air is cooled using a refrigeration system. This cooling allows the air components to condense, facilitating their separation.

Distillation Once cooled, the air is introduced into a distillation column. In this column, the principle of fractional distillation is used to separate the different components.

Separation of Argon Argon can be isolated during the distillation process, since it has a lower boiling point than other gases present in the air, such as nitrogen and oxygen. This property allows argon to be separated and collected in its pure form.

Purification The argon obtained in the previous step is subjected to an additional purification process to eliminate any impurities or contaminants that may be present.

Packaging Finally, the purified argon is packaged in suitable containers for subsequent distribution and use as an E938 additive in the food industry, where it is used as an inert gas to preserve food. It is important to note that the process described may vary depending on the technology and equipment used in each particular case, but air distillation is the most commonly used method to obtain the E938 additive.
