Patent number: 9011579Abstract: This disclosure describes embodiments of an air treatment apparatus that stimulates formation of large moisture droplets from small moisture droplets found in air flowing in power generating systems to a turbo-machine. In one example, the embodiments generate a field that promotes contact between the smaller moisture droplets. This contact can increase the size of moisture droplets to facilitate condensation of moisture out of the air.Type: GrantFiled: June 13, 2012Date of Patent: April 21, 2015Assignee: BHA Altair, LLCInventors: Abhijeet Madhukar Kulkarni, Martin Gregory Hatfield, Richard Michael Ashley Mann
