Deep Function Experience & Measured Results

Waste-to-Energy Plant Flue Gas Desulfurization
Testing Scenario & Need: The plant previously used sodium bicarbonate, which had high consumption and large amounts of non-recyclable byproducts, leading to high operation costs.
Actual Testing Process: Replaced sodium bicarbonate with Vanda's sorbent, running continuously for 3 months with real-time emission monitoring.
Measured Results: SO₂ concentration remained stable at ≤35mg/Nm³, with fluctuation within ±5mg/Nm³, fully meeting national and local standards. Sorbent consumption dropped from 18-20kg per ton of waste to 6kg.
Solved Pain Points: Reduced comprehensive operation costs by 30%+, cut byproduct volume by 60%.

Multi-Pollutant Removal
Testing Scenario & Need: The plant required additional equipment to remove HCl and HF, increasing investment and maintenance.
Actual Testing Process: Used Vanda's sorbent without additional equipment, monitored HCl and HF emissions.
Measured Results: HCl and HF removal rates reached ≥90%, with simultaneous reduction of dioxins and heavy metals.
Solved Pain Points: Eliminated need for extra treatment equipment, reduced maintenance frequency by 25%.

Measured Performance Data Comparison

Core Performance Indicator | Official Nominal Value | Actual Measured Value | Testing Conditions | Compliance Evaluation
Surface Area | ≥50m²/g | 52m²/g | Laboratory analysis | Fully compliant, exceeds nominal
Desulfurization Efficiency | ≥97% | 98.2% | Waste-to-energy plant continuous operation | Exceeds nominal
Calcium-Sulfur Ratio | 1.2-1.5 | 1.3 | Real-time flue gas monitoring | Fully compliant
Unreacted Ca(OH)₂ in Byproduct | ≤5% | 4.2% | Post-reaction sample analysis | Fully compliant

Pros & Cons

Core Advantages
1. Exceptional Efficiency & Cost Reduction: Measured sorbent consumption reduced by 20%-40%, cutting operation costs by 30%+ for industrial plants.
2. Multi-Pollutant Removal: Simultaneously removes SO₂, HCl, HF, dioxins, and heavy metals, eliminating need for extra treatment systems.
3. Eco-Friendly Byproducts: Byproduct with ≤5% unreacted Ca(OH)₂ can be reused as building materials or soil conditioner, no secondary pollution.
Real Disadvantages
1. Custom Lead Time: Custom sorbents with surface area >80m²/g require a 2-week lead time. Solution: Plan procurement in advance.
2. Storage Requirement: Needs dry, sealed storage to avoid caking. Solution: Use moisture-proof warehouses or sealed containers.

Suitable Users & Scenarios

Ideal for:
- Steel, waste-to-energy, cement, glass, coking industries needing flue gas treatment
- Plants with high-temperature flue gas (40-430℃) and multi-pollutant removal needs
