摘要： A system and method for reducing foaming in a wet scrubber system. The system utilizes a device for measuring the volume of entrained gas in the wet scrubbing system, and automatically or semi-automatically adjusting one or more process parameters including: a flow rate of antifoam/ defoamer chemistry in said wet scrubber; a flow rate of flue gas; and a flow rate of fresh water. The system allows real-time monitoring and control of the foam in said wet scrubber.

摘要： The invention comprises one or more gas volume fraction measurement devices operatively connected to one or more controllers and one or more deaeration mechanisms which receive control signals from said one or more controllers and perform an act on the system, such as by controlling a level of deaeration chemistry into some portion of the fermentation system. In one embodiment, the deaeration mechanism is an antifoam feed pump which pumps antifoam chemistry into a feed line of the fermenter in response to the measured gas volume fraction in the fermenter's recirculation loop, in an amount determined by the controller to be effective to reduce foaming and lower column height in the fermenter.
