FAQS

The product has obtained certification from the international SGS testing agency and holds more than 80 proprietary technology patents. It is backed by real-world operational data collected from over 500 customers, including Everbright Environment and Shandong Iron & Steel, and can provide a comprehensive set of supporting documents, including project implementation case studies, test reports, and patent certificates.

The core business model is direct manufacturing and sales, with the company pursuing a global market strategy. For import‑export operations, we can provide a complete set of import‑export compliance documents, along with corresponding overseas compliance test reports (SGS testing and certification).

Our target customers include lime plants, calcium powder manufacturers, and chemical plants. We can customize complete production line equipment based on the customer’s existing lime‑granule feedstock, offering a one‑stop, end‑to‑end solution that encompasses both hardware and process technology. The production lines deliver stable operation and high throughput.

Flue gas corrosivity is significantly reduced, leading to decreased corrosion of filter bags, pipelines, and flue ducts. The service life of filter bags is extended by more than 30%, and the frequency of equipment maintenance as well as downtime for repairs are markedly reduced.

The desulfurization reaction is complete, with the unreacted Ca(OH)₂ in the by-products accounting for no more than 5%, resulting in high‑purity calcium sulfate. The product can be directly sold as a building material or soil amendment, while total solid waste generation is simultaneously reduced, with no secondary pollution and no increase in carbon emissions.

When the calcium-to-sulfur ratio is maintained within the 1.2–1.5 range, desulfurization agent consumption is reduced by 20%–40%. Taking the Everbright Waste-to-Energy Plant as an example, the amount of desulfurization consumables required for waste incineration has dropped from 18–20 kg to 6 kg, resulting in a substantial reduction in overall operation and maintenance costs.

1. Conventional desulfurization consumes large quantities of materials and incurs high operating costs; 2. Excessive spray can corrode the reaction tower and flue ducts, while baghouse filters experience rapid wear; 3. Desulfurization byproducts generate substantial solid waste that is difficult to dispose of; 4. Coordinated control of multiple flue‑gas pollutants is inadequate, posing a high risk of exceeding regulatory limits for dioxins and heavy metals.

It is compatible with flue‑gas desulfurization applications across the entire steel, coking, industrial silicon, cement and building materials, glass, ceramic, waste‑to‑energy, refractory, carbon, and sodium silicate industries, and can fully replace the baking‑soda‑based desulfurization process.

The finished product exhibits a stable specific surface area of ≥50 m²/g, with custom formulations reaching 40–100 m²/g; it features a highly developed pore structure and high screening pass-through rates, maintains consistent performance under prolonged continuous operation, and keeps SO₂ emissions within a fluctuation range of ±5 mg/Nm³.

① Adapts to a wide range of operating conditions with flue gas temperatures from 40 to 430°C, featuring small temperature drops, excellent fluidity, and exceptionally high activity; ② Achieves desulfurization efficiencies exceeding 97%, with low capital investment and zero discharge of wastewater or solid waste; ③ Requires no water consumption, and the desulfurization by-products can be recovered and reused as resources; ④ Simultaneously achieves highly efficient removal of acidic gases such as HCl and HF.

We have provided stable, end-to-end services to a total of 500 industry clients, with benchmark partners including leading steel and solid-waste-to-energy companies such as Shandong Iron & Steel, Shandong Nai, and Everbright Environment.

Annual output value of RMB 200 million, with an annual production capacity of 300,000 tons for core desulfurization products; supporting high‑specific‑surface‑area calcium hydroxide production lines, each with an annual capacity of 50,000 to 100,000 tons, and customizable line configurations available upon request.

We have an in-house professional R&D team comprising 3 PhDs, 10 graduate students, and more than 30 senior engineers. The company is equipped with a full suite of specialized testing equipment, holds over 80 patents, and allocates 30% of its annual revenue to R&D.

The company’s core business is high-efficiency calcium-based desulfurization agents, with a focus on its high‑specific‑surface‑area calcium hydroxide product line. Its brand‑promotion slogan is: “Wanda Desulfurization—Serving the World.”
