All-Volatile Treatment - an overview | ScienceDirect

4.5.1 All-volatile treatment (AVT) AVT is defined as the exclusive use of volatile conditioning agents. Volatile chemicals evaporate from the water into the steam in a gaseous form. When steam condenses, the chemicals dissolve into the water. They do not form a solid phase and thus they do not form a scale or deposit on heat transfer surfaces.
