Functional Experience & Measured Results

Waste Incinerator Flue Gas Desulfurization Performance

Testing Scenario & Needs: The plant faced high operational costs from sodium bicarbonate desulfurizer, frequent filter bag replacement due to corrosion, and large amounts of non-recyclable by-products. Usage & Testing Process: Replaced 100% of sodium bicarbonate with Vanda’s desulfurizer, maintained continuous operation for 3 months, monitored emissions daily, and tracked consumption and by-product quantity. Results: SO₂ emissions stabilized at ≤30mg/Nm³, well below national standards. HCl and HF removal rates reached 92% and 90% respectively. Desulfurizer consumption dropped from 18-20kg per ton of waste to 6kg, a 67% reduction. Solved Pain Points: Significantly reduced operational costs, minimized filter bag corrosion, and eliminated non-recyclable solid waste.

By-Product Handling & Environmental Impact

Testing Scenario & Needs: Previous by-products required landfill disposal, increasing environmental costs and compliance risks. Usage & Testing Process: Collected and analyzed by-product composition monthly, tested its suitability as building material additive. Results: Unreacted Ca(OH)₂ content was ≤3.8%, with high-purity calcium sulfate. The by-product was successfully sold to a local building material factory, eliminating landfill needs and creating additional revenue. Solved Pain Points: Eliminated secondary pollution, reduced solid waste disposal costs, and achieved resource recycling.

Performance Data Comparison

All data was collected in actual plant operating conditions, not laboratory environments, ensuring real-world reference value.

Pros & Cons

Core Advantages
1. Exceptional Cost Reduction: Cut desulfurizer consumption by 67% in the waste incinerator test, significantly lowering operational expenses while maintaining high desulfurization efficiency
2. Low Environmental Impact: Produces recyclable by-products with no secondary pollution, helping plants meet strict environmental regulations and reduce solid waste disposal costs
3. Wide Temperature Adaptation: Performed reliably across flue gas temperatures from 120℃ to 380℃, eliminating the need for temperature adjustment systems

Real Disadvantages
1. Customization Lead Time: Customized products with specific surface area require a 2-week lead time, which may not suit urgent project timelines
Plan ahead for custom orders or choose standard products for immediate needs.
2. Storage Requirements: Needs dry, sealed storage to prevent moisture absorption, which may require additional warehouse facilities for bulk inventory
