Activated carbon plays an important role in the iron and steel industry. Companies operating in this sector can make their production more efficient by taking advantage of the various applications of activated carbon.

Activated carbon is used in many stages of iron and steel production. For example, it can be used to purify exhaust gases. Gases released during iron and steel production are often contaminated with high temperatures and pollutants. Activated carbon is used in gas purification systems to absorb these pollutants and reduce the release of pollutants into the environment. The high adsorption capacity of activated carbon makes it possible to effectively separate harmful compounds from gases. It can also be used in water treatment, for example. Large quantities of water are used in iron and steel production, and the purification of this water is an important step. Activated carbon can be used effectively in the purification process by adsorbing organic pollutants, colourants and heavy metals in the water. Activated carbon also helps to improve water quality by removing odours and flavours from the water. Further areas of application will be discussed shortly.

The advantages of using activated carbon in the iron and steel industry are also worth mentioning. First of all, it offers a great environmental advantage. Thanks to the absorption of waste gases and pollutants, air and water pollution is reduced. This minimises the environmental impact and ensures an environmentally friendly production process.

In addition, the use of activated carbon increases production efficiency. The removal of impurities and pollutants ensures a longer service life for production facilities and equipment. Activated carbon also improves product quality by reducing unwanted by-products in the production process. The better quality of the products increases the competitiveness of the companies and strengthens their market share.

Finally, the use of activated carbon is also important in terms of sustainability. The purification of waste gases and water enables a more efficient use of resources. Activated carbon can also be recycled, which offers advantages in terms of resource conservation and waste management.

Overall, activated carbon is an important solution for reducing environmental impact, increasing production efficiency and improving product quality in the iron and steel industry. Companies can increase their competitiveness and support their sustainability goals by utilising the benefits of activated carbon.

Some uses of activated carbon in iron and steel production:

Steel production: activated carbon plays a role in several important processes in steel production. For example, activated carbon is used to purify blast furnace gas. It improves the quality of steel production and minimizes its environmental impact by removing harmful pollutants (e.g. sulfur compounds) from the blast furnace gas. In addition, activated carbon can also be used to control gas bubbles in oxygen atomizers used in the production of liquid steel.
Clarification processes: Activated carbon plays an important role in water and waste gas purification processes in iron and steel production. Activated carbon is integrated into filters or adsorption systems to purify the exhaust gasses produced in steelworks. Activated carbon adsorbs harmful gasses (e.g. hydrogen sulfide) and thus reduces their release into the environment. Activated carbon filters are also used to purify cooling or process water used in steel production.
Liquid metal cleaning: Activated carbon is also frequently used in the purification of liquid metals in iron and steel production. In foundries in particular, activated carbon filters are used to remove solid particles and impurities from the liquid metal. This improves the quality of the casting process and ensures that the end products have the desired properties.
Purification of blast furnace gas in blast furnaces: activated carbon purifies the gas flow by adsorbing harmful gasses (e.g. CO, CO2, SO2) in the blast furnace gas. This reduces the amount of pollutants released into the atmosphere during iron and steel production and minimizes environmental pollution.
Water treatment: Activated carbon is used to purify the water used in iron and steel production. Activated carbon purifies the water from pollutants such as organic substances, dyes and bad odors, thus ensuring purer water.
Exhaust gas treatment: Activated carbon can be used to remove sulfur compounds from process gas. This improves air quality and reduces the impact of industrial waste on the environment.
Purification of foundry gas: In iron and steel production, it is important to purify the gasses in the foundry. Activated carbon ensures a clean air flow by adsorbing various pollutants (e.g. VOCs, sulfur compounds) from foundry gas.
Cleaning the cooling water system: Cooling water is used in iron and steel production. The quality of this water is important, and activated carbon helps to clean organic substances, odors and dyes. This increases the efficiency of the cooling water and extends the service life of the system.
Control of gas discharge: The gasses generated during iron and steel production can contain many harmful compounds. By purifying the exhaust gasses, activated carbon reduces harmful emissions into the atmosphere and protects air quality.
Waste water treatment: Iron and steel production can generate waste water. Activated carbon improves the quality of wastewater and reduces the impact on the environment by adsorbing organic compounds, heavy metals and other pollutants in wastewater
Disinfection and Sterilization: Water resources used during iron and steel production can create a suitable environment for the growth of microorganisms. Activated carbon provides disinfection and sterilization by adsorbing microorganisms in water. This helps maintain a hygienic production environment.
Non-Coking Coal Production: Non-coking coal (anthracite) is used in iron and steel production. Activated carbon can improve the quality of coal used in the non-coking coal production process. Activated carbon supports the production of purer and higher-quality coal by adsorbing the volatile substances and pollutants contained in coal.
Catalyst Carrier: Activated carbon can also be a catalyst carrier in iron and steel production. In particular, loading catalysts onto activated carbon in gas-phase reactions can increase reaction efficiency and improve product quality.
Air Purification: There are many processes in the iron and steel industry where air quality is essential. Activated carbon is used in air purification systems to help remove volatile organic compounds (VOCs), hydrogen sulfide (H2S), ammonia (NH3) and other harmful gases. In this way, a healthy and safe working environment is provided in the workplace.
Dust Control: Dust formation is inevitable in iron and steel production. Activated carbon reduces the dust concentration in the air by adsorbing dust particles. This helps ensure a clean air environment and protects employees' health.
