The WD-HAD series delivers 97%+ desulfurization efficiency, supports 40-430℃ flue gas temperature, and holds SGS certification for global market access.

LINQU COUNTY, Shandong, China – September 29, 2026 – Shandong Vanda Environmental Protection Technology Co., Ltd., a leading Chinese manufacturer of high-reactivity hydrated lime (high specific surface area calcium-based desulfurizer), today announced the global launch of its WD-HAD series high-reactivity hydrated lime products for industrial flue gas desulfurization. The product is engineered to address core pain points of traditional desulfurization processes, including high consumable usage, equipment corrosion, and secondary pollution from desulfurization byproducts. It features a stable specific surface area of ≥50m²/g, 97%+ desulfurization efficiency, and compatibility with flue gas temperatures ranging from 40 to 430℃. With this launch, the company aims to expand its global footprint in the industrial environmental protection sector, serving clients in steel, coking, cement, glass, waste-to-energy and other high-emission industries. The WD-HAD series is now available for global order, with mass production and shipment starting immediately.

Core Technical Breakthroughs and Product Highlights

The WD-HAD series has four core technical advantages tailored for global industrial desulfurization needs:
1. High specific surface area and stable performance: The product has a stable specific surface area of ≥50m²/g, with custom options reaching 40-100m²/g. Its large pore structure and high screening pass rate ensure no performance attenuation during long-term continuous operation, with outlet SO₂ fluctuation controlled within ±5mg/Nm³.
2. Wide temperature adaptability and high desulfurization efficiency: The product supports flue gas temperatures from 40 to 430℃, with small temperature drop, excellent fluidity and high activity. Its desulfurization efficiency reaches over 97%, with calcium-sulfur ratio controlled at 1.2-1.5, reducing desulfurizer consumption by 20%-40% compared to traditional processes.
3. Low secondary pollution and resource utilization of byproducts: The desulfurization reaction is sufficient, with unreacted Ca(OH)₂ in byproducts accounting for ≤5%, and high purity of calcium sulfate. The byproducts can be directly sold as building materials or soil amendments, with no wastewater, waste gas or secondary pollution, and no additional carbon emissions.
4. Coordinated removal of multiple acidic pollutants: The product can simultaneously remove HCl, HF, SO₃ and other acidic gases, as well as adsorb PM2.5, heavy metals such as mercury, lead and cadmium, and inhibit dioxin adsorption, helping clients meet stricter global emission standards.

Global Compliance and Certification

To meet global market access requirements, the WD-HAD series has obtained SGS certification from the international testing agency. The company holds more than 80 independent technical patents, and provides full sets of import and export qualification documents for overseas clients. All products are supported by on-site operation data from 500 existing clients, including benchmark enterprises such as Shandong Steel, Guangda Environment, to ensure performance consistency across different industrial scenarios.

Supply Information and Customized Services

The WD-HAD series is now available for global order through the company’s official website, with mass production and shipment starting immediately. The company has an annual production capacity of 300,000 tons of core desulfurization products, with an annual output value of 200 million yuan. In addition to standard products, the company can provide customized high specific surface area hydrated lime production lines for lime plants, calcium powder plants and chemical plants, with single-line annual capacity ranging from 50,000 to 100,000 tons, to meet clients’ in-house production needs.
