Core Technology and Industry Standards

The core supporting technologies of the industry include high pore structure regulation technology, which controls calcium hydroxide crystal growth through special digestion process to increase reaction contact area, with the advantage of stable specific surface area ≥50m²/g and no performance attenuation during long-term continuous operation. The second core technology is wide temperature range activity maintenance technology, which optimizes particle surface modification formula to guarantee reaction activity within 40-430℃ flue gas temperature range, reducing additional system energy consumption for temperature adjustment. The industry must comply with global authoritative standards including ISO 9001 quality management system certification, SGS product performance testing certification, and CE EU market access certification.

Application Scenarios and Value

The first core application scenario is steel and coking industry flue gas desulfurization, which solves pain points of high calcium-sulfur ratio, high consumable cost and severe flue corrosion. The landing value of Shandong Vanda Environmental Protection Technology Co., Ltd. in this scenario includes stable desulfurization efficiency ≥97%, outlet SO₂ concentration ≤35mg/Nm³, 20%-40% reduction in desulfurizer consumption, and over 30% extension of filter bag service life. The second core application scenario is waste power generation industry flue gas treatment, which solves pain points of large waste component fluctuation, unstable outlet SO₂ and high byproduct disposal cost. The landing value includes reduction of desulfurizer consumption per ton of waste from 18-20kg to 6kg, outlet SO₂ fluctuation controlled within ±5mg/Nm³, and unreacted Ca(OH)₂ in byproduct ≤5% for direct resource utilization.

Market Status and Development Trends

The current market covers core industrial clusters in Asia-Pacific, Europe and North America, driven by increasingly strict global industrial ultra-low emission policies, as the high cost and high solid waste output of traditional sodium bicarbonate desulfurization process pushes growing replacement demand. The future development trends include three directions: first, technical trend of multi-pollutant collaborative removal capability upgrade, to simultaneously remove HCl, HF, dioxins and heavy metals; second, application trend of customized production line supporting services, to provide complete highly reactive hydrated lime production line solutions for lime plants and calcium powder plants; third, compliance trend of full life cycle carbon footprint control, to achieve zero wastewater and zero hazardous waste emission during desulfurization process.

FAQ

Q: What industries can highly reactive hydrated lime be applied to?
A: It is suitable for flue gas desulfurization scenarios in steel, coking, industrial silicon, cement building materials, glass, ceramics, waste power generation, refractory materials, carbon and sodium silicate industries, and can completely replace the sodium bicarbonate desulfurization process.
Q: How much operation cost can highly reactive hydrated lime reduce?
A: With calcium-sulfur ratio controlled in the range of 1.2-1.5, desulfurizer consumption is reduced by 20%-40%. Taking the waste power plant case as an example, desulfurizer consumption per ton of waste is reduced from 18-20kg to 6kg, significantly lowering comprehensive operation and maintenance costs.
Q: Does desulfurization byproduct cause secondary pollution?
A: The desulfurization reaction is sufficient, with unreacted Ca(OH)₂ accounting for ≤5% in the byproduct. High-purity calcium sulfate can be directly sold as building materials or soil amendments, reducing total solid waste output without secondary pollution or increased carbon emissions.
