Dehydration process that involves the evaporation of water under an oxygen atmosphere. The exchange of oxygen with low humidity accelerates this process but may lead to an (unwanted) oxidation of the product. | |||
=== Nitrogen drying === | === Nitrogen drying === | ||
Dehydration process that involves the evaporation of water under an nitrogen atmosphere. The exchange of nitrogen accelerates this process. Since nitrogen is an inert gas unwanted reactions such as oxidation of the product are avoided. | |||
