In many processes of the chemical industry hydrous solutions are enriched with gas which is found to be troublesome when re-using the solution (e.g. spinbath in viscose fiber factories). There are different methods of degassing solutions.

Ebner developed the degassing in vacuum being one of the optimum variants.

In case of a single-stage vacuum degassing plant the solution is fed into a vacuum vessel. During this procedure noxious gases and also air are expelled to a great extent. If a second stage is connected to the first one in which water is evaporated at the same time, serving as carrier gas for a better degassing, optimum degassing effects can be achieved.
