What does deoxygenating mean?
Deoxygenating means removing oxygen from a substance, environment, or system. The word is used especially in technical contexts involving water treatment, blood processing, metallurgy, chemical manufacture, and the handling of gases. In a plant, for example, inert gases such as nitrogen may be introduced to reduce the oxygen in a tank, helping prevent oxidation or the formation of explosive mixtures. In medicine, deoxygenating blood is a deliberate process, not merely the accidental loss of oxygen that occurs naturally. The term can also describe an action or a device, as in “a deoxygenating unit.” It should not be confused with dehydrating, which removes water rather than oxygen. As an -ing form of deoxygenate, deoxygenating is normally used in ongoing or deliberate actions, while the related noun deoxygenation names the process itself.
To remove oxygen from a substance, environment, or system.
"Nitrogen is used to keep the tank from deoxygenating the oil."
The -ing form is commonly used for an ongoing or deliberate process in technical writing.
Serving to remove oxygen from a substance, environment, or system.
"The deoxygenating chamber reduced the oxygen level before processing."
This participial use occurs mainly before nouns in technical descriptions.
A tank can be deoxygenated without being dried: the missing ingredient is oxygen, not water.

Where does deoxygenating come from?
The English verb deoxygenate was formed from the prefix de-, meaning reversal or removal, combined with oxygen and the verbal suffix -ate. Oxygen itself was coined in the late eighteenth century from Greek roots meaning “sharp” or “acid-producing” and “producing.” The related forms oxygen, oxide, and oxidation belong to the same modern scientific vocabulary centered on oxygen and its chemical behavior.
