AI Overview
Anti-foaming agents for power plant desulfurization (FGD) are specialized, high-temperature, and acid/alkali-resistant chemicals—commonly polyether or silicone-based—designed to eliminate slurry foam. They prevent false high-level alarms, stop slurry overflow, and enhance absorption tower efficiency. Popular options include polyether lotions, silicone-based agents, and products like Foamtrol 2290 or Nalco FM-37.
