The upgraded WD-HAD series from Shandong Vanda Environmental Protection Technology Co., Ltd. delivers 97%+ desulfurization efficiency, cutting operating costs of customers by 20-40% for industrial flue gas treatment scenarios.

WEIFANG, China – October 23, 2026 – Shandong Vanda Environmental Protection Technology Co., Ltd., a leading provider of chemical environmental protection solutions, today announced the official launch of its upgraded WD-HAD series high surface area hydrated lime, designed for acid gas removal across industrial flue gas treatment scenarios. The product is engineered to address core pain points of traditional desulfurization processes, including high material consumption, equipment corrosion and secondary pollution from desulfurization byproducts. With a desulfurization efficiency of over 97%, the product can fully replace traditional sodium bicarbonate desulfurization processes, helping global industrial customers meet ultra-low emission compliance requirements while reducing overall operating costs. The WD-HAD series is now available for global order booking, with mass production and shipping scheduled to begin in late October 2026.

Core Technical Performance Advantages

The WD-HAD series high surface area hydrated lime is manufactured with optimized porous structure and high activity, delivering verified performance across key desulfurization metrics:
1. Wide temperature adaptability: The product operates stably across 40-430℃ flue gas conditions, with minimal temperature drop, excellent fluidity and reaction activity, eliminating the need for pre-treatment of low-temperature flue gas.
2. Stable emission compliance: Desulfurization rate reaches over 97%, with outlet SO₂ concentration fluctuation controlled within ±5mg/Nm³ even when flue gas composition varies, ensuring consistent compliance with ultra-low emission standards.
3. Reduced operating cost: With a calcium-sulfur ratio of 1.2-1.5, desulfurizer consumption is reduced by 20-40% compared to traditional materials. For reference, a waste-to-energy plant customer saw per-ton waste desulfurizer consumption drop from 18-20kg to 6kg after adopting the product.
4. Co-benefit pollutant removal: The product simultaneously removes HCl, HF, SO₃, heavy metals and dioxins, reducing the need for additional multi-pollutant treatment equipment.
5. Zero secondary pollution: Unreacted Ca(OH)₂ in desulfurization byproducts accounts for ≤5%, with high-purity calcium sulfate that can be directly sold as building materials or soil amendments, eliminating hazardous waste disposal costs.

Global Compliance and Certification

To meet global market access requirements, the WD-HAD series has obtained SGS international testing certification, with full compliance with industrial flue gas treatment standards across the EU, North America and Asia-Pacific regions. The company holds 80+ independent technical patents, and provides full sets of import/export qualification documents and third-party test reports for overseas customers.

Supply and Customization Services

The WD-HAD series is available for global order booking via the official website of the company starting immediately, with mass production and global shipping scheduled to begin in late October 2026. The company also offers customized high surface area hydrated lime production line solutions for lime plants, calcium powder processing facilities and chemical enterprises, tailored to raw material conditions and production capacity requirements of customers.

Executive and Customer Statements

“ The launch of the upgraded WD-HAD series marks a key step in the global expansion strategy of the company, ” said Jian Liu, General Manager of Shandong Vanda Environmental Protection Technology Co., Ltd. “ We have spent over a decade optimizing the performance of the product to address the most pressing pain points of industrial flue gas treatment, and we are confident that our cost-effective, compliant solutions will help more global customers meet their emission reduction targets. ”
“ We have been using the desulfurizer of Vanda for over two years, and have seen a 60% reduction in desulfurization material costs, as well as a 30% extension of filter bag service life, ” said a representative from the Tianjin waste-to-energy plant of Everbright Environment.
