Desulfurization Defoamer: The "Foam Terminator" for Clean Air | Chemi Tech Solution

In the purification process of industrial flue gas from power plants and steel mills, wet flue gas desulfurization (FGD) systems play a crucial role in controlling SO₂ emissions. However, this environmental guardian is often troubled by an "invisible enemy" - foam. These seemingly harmless bubbles actually pose serious risks, not only reducing desulfurization efficiency but also potentially causing equipment damage and gypsum quality deterioration.

The "Silent Killer" in Desulfurization Systems: Hazards of Foam

In FGD absorber towers, the slurry containing abundant surfactants combined with bubbles generated during forced oxidation easily forms stable foam layers. This foam causes three major problems:

One large power plant saw its desulfurization efficiency drop from 98% to 85% due to foam issues, resulting in nearly 1,000 tons of additional SO₂ emissions annually and heavy environmental penalties.

Chemi Tech Desulfurization Defoamer: Technology Empowering Environmental Protection

Addressing the special conditions of FGD systems, Chemi Tech's R&D team has developed a new generation of high-efficiency defoamers after years of research. Using specially modified silicone as the main component, our product offers outstanding advantages:

1、Fast foam breaking: Penetrates foam film structure within 30 seconds
2、Long-lasting suppression: Resists high temperature and pH, effective for over 24 hours
3、 Environmentally safe: VOC-free, doesn't affect desulfurization reactions
4、 Cost-effective: Dosage only 1/3 of conventional products, reducing overall cost by 40%

Success Story: From Challenge to Breakthrough

A 2×1000MW unit at Huaneng Power struggled with persistent foam problems, experiencing significant absorber level fluctuations and high gypsum moisture content. After adopting Chemi Tech desulfurization defoamer:
