High-reactivity hydrated lime prevents de novo dioxin formation in the 200–400 °C flue-gas window via chlorine scavenging and Damköhler-based design

Key Points

• Dioxin formation is prevented in the 200–400 °C flue-gas window with hydrated lime, ensuring safer emissions.
• Key evidence indicates a reduction in dioxin levels, specifically targeting chlorine scavenging capability.
• Analysis focuses on the chemical reactions involved during flue-gas processing at high temperatures, incorporating Damköhler principles.
• High-reactivity hydrated lime offers a promising solution for reducing dioxin emissions; further field applications should be explored.
