Vanda Environmental Protection Technology Desulfurizer - High Specific Surface Area Calcium Hydroxide (High Activity Calcium Hydroxide)
Author:
The desulfurization absorption and product treatment of the high-activity, high-specific surface area calcium hydroxide desulfurization (powder) technology are carried out in a dry state. This method has the advantages of no wastewater or waste acid discharge, less equipment corrosion, no significant temperature drop in the flue gas during purification, high flue gas temperature after purification, which is conducive to chimney exhaust gas diffusion, and less secondary pollution. It is a suitable flue gas desulfurization technology for industries such as steel, coking, cement, glass, and ceramics.
The high specific surface area calcium hydroxide produced by Vanda Environmental Protection Technology Co., Ltd. has been used in dry desulfurization for a long time under complex operating conditions of various flue gases in many enterprises, such as coal-fired lime kilns, metallurgical aluminum smelting furnaces, coke ovens, and garbage power generation. The desulfurization efficiency can reach more than 97% (experimental report examples 97.33%-99.7%), and strategic cooperation projects have been signed with many enterprises.
High specific surface area calcium hydroxide, as a strong alkaline inorganic non-metallic powder, has a specific surface area more than 3 times that of ordinary calcium hydroxide. It has unparalleled advantages in gas adsorption, reaction activity, fluidity, and reaction speed, therefore, it has broad application prospects. In the environmental protection field, it can be used for flue gas desulfurization and wastewater treatment. High specific surface area calcium hydroxide, replacing sodium bicarbonate, is currently recognized internationally as an excellent dry desulfurization product; in the construction field, it can be used as an admixture for high-performance concrete, waterproof materials, etc.; in the chemical industry field, it can be used as raw materials and additives for fine chemical products, etc. At the same time, the application value of high specific surface area calcium hydroxide is also becoming increasingly prominent in the food, medicine, and new energy fields.

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-Area Calcium Hydroxide in Flue-Gas Desulfurization in the Ceramic Industry
Ceramic tunnel kilns and roller hearth kilns experience frequent flue gas temperature fluctuations, high dust concentrations, and uneven sulfur content. Moreover, production facilities demand stringent environmental cleanliness, while conventional desulfurization methods often generate wastewater and water mist, compromising ceramic product quality. The high‑specific‑surface‑area calcium hydroxide dry‑process desulfurization technology is well suited to the operational conditions and environmental requirements of the ceramics industry.

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.
