This is only one application for a degasser and probably not a common one at that. A degasser is a vessel (or can be a cyclonic device) used for separation of gas from a fluid. Typical applications are for removing entrained gas from produced oil or water - ie a first and second stage separator is a degassing vessel. A degassing vessel relies on the principle of Boyles law where the volumetric area in which the fluid is contained allows the liberation of gas to occur.

Hope this helps
