Application of High-Specific-Surface-Area Calcium Hydroxide in Flue-Gas Desulfurization for the Waste Incineration Industry

Author:


The flue gas from waste incineration is highly complex, containing not only SO₂ and SO₃ but also HCl, HF, and heavy metal pollutants, and it is prone to dioxin formation. With its strong corrosivity and the significant challenges of treatment, it represents a key focus area in environmental protection. High‑specific‑surface‑area calcium hydroxide, which simultaneously achieves desulfurization, deacidification, and impurity removal, serves as a core material for controlling waste‑incineration flue gas.
Its well-developed pore structure can physically adsorb heavy metal particulates and dioxin precursors from flue gas, while rapidly neutralizing various acidic gases, thereby enabling the synergistic control of multiple pollutants. Even under short‑contact‑time conditions, it maintains exceptionally high reaction efficiency, making it well suited to the continuous operation of waste incineration furnaces.
Practical applications have demonstrated that this material can reliably keep the emissions of sulfides and acidic gases from incineration flue gas within regulatory limits, meeting the stringent environmental standards of both the European Union and China. The entire dry‑process treatment system generates no wastewater, produces stable, non‑hazardous by‑products that can be safely disposed of or recovered for resource utilization, and effectively addresses the issue of secondary pollution in waste‑incineration flue gases, making it suitable for a wide range of municipal solid waste and other solid‑waste incineration‑to‑energy projects.

Application of High-Specific-Surface-Area Calcium Hydroxide in Flue-Gas Desulfurization for Industrial Kilns in the Chemical Industry

In the chemical industry, flue gases from various reaction kilns and heating furnaces are highly complex; in addition to sulfides, they often contain small amounts of acidic organic compounds. These flue gases are highly corrosive, and conventional desulfurization agents exhibit limited reactivity and poor corrosion resistance, resulting in only modest treatment performance. High‑specific‑surface‑area calcium hydroxide can achieve simultaneous desulfurization and deacidification, making it well suited to the complex flue‑gas conditions encountered in chemical processes.

Application of High-Specific-Surface-Area Calcium Hydroxide in Flue Gas Desulfurization in the Refractory Materials Industry

Refractory‑material tunnel kilns and shuttle kilns operate at high temperatures and produce uneven flue‑gas emissions; their intermittent operation further causes significant fluctuations in sulfur content, placing extremely stringent demands on the desulfurizing agent’s instantaneous reaction kinetics and operational adaptability. High‑specific‑surface‑area calcium hydroxide, with its high reactivity and rapid response, is well suited to meet the desulfurization requirements of the refractory industry’s batch‑type production processes.

Application of High-Specific-Surface Calcium Hydroxide in Flue Gas Desulfurization in the Industrial Silicon Industry

The flue gas from industrial silicon smelting furnaces is characterized by high temperatures, extremely high dust concentrations, and abundant sulfide‑containing impurities, resulting in harsh operating conditions. Conventional desulfurization agents are prone to failure, leading to poor desulfurization stability—making this a significant challenge in industrial flue‑gas treatment. High‑specific‑surface‑area calcium hydroxide, with its strong adaptability and excellent penetration, is ideally suited to the desulfurization of flue gases generated during industrial silicon smelting.

Application of High-Specific-Surface Calcium Hydroxide in Flue Gas Desulfurization in the Glass Industry

Glass kilns typically use heavy oil and natural gas as fuels, producing flue gases with unique sulfur content, high temperatures, and stable flow rates. Conventional desulfurization processes often suffer from incomplete removal of sulfur compounds, equipment fouling, and excessive energy consumption. High‑specific‑surface‑area calcium hydroxide is specifically tailored to the characteristics of glass‑kiln flue gases, enabling efficient, low‑cost desulfurization.
