In power plant desulfurization, excessive foam causes serious problems: absorber overflow, reduced desulfurization efficiency and higher system energy consumption. Many companies struggle with difficult foam control, defoamers that do not last, or products that compromise desulfurization itself. Drawing on years of technical accumulation, Chemi Tech has developed a high-efficiency defoamer dedicated to power plant desulfurization, precisely addressing complex working conditions.
We propose the following solution:
1. Problem diagnosis and analysis: on-site surveys and foam sample testing identify the main causes of foam generation.
2. Customized defoamer selection: a matching product is recommended based on slurry composition, pH and temperature.
3. Dosing plan optimization: dosing points, dilution ratios and dosing frequency are specified to avoid overdosing.
4. Performance monitoring and adjustment: foam dynamics are tracked regularly and process parameters adjusted in time.
After a power plant adopted the Chemi Tech defoamer in its desulfurization system, foam overflow was brought under control, desulfurization efficiency rose by about 12%, and foam-related equipment maintenance became less frequent. The customer reported strong product stability with no impact on the quality of desulfurization by-products.
Chemi Tech defoamers are alkali-resistant and high-temperature resistant, dissolving and dispersing rapidly, and suit different FGD processes such as limestone-gypsum and ammonia methods. We provide full-process technical collaboration to help users achieve low-cost, high-benefit foam management.
