Sorbalite for Scrap Iron Recycling Foundry

In the field of metal recovery and recycling, foundries processing ferrous scrap face significant environmental challenges related to waste management and emissions during the melting process. The fumes generated by melting ferrous scrap contain harmful pollutants, including acid gases such as sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), as well as heavy metals such as chromium (Cr), nickel (Ni), and lead (Pb). The presence of these pollutants requires effective treatment to minimize environmental impact.

Solution with Sorbalite

To address these issues, the use of Sorbalite, an additive combining hydrated lime and activated carbon, offers an innovative and efficient solution. It is injected dry into the exhaust gas ducts via a system with a doser that regulates the correct amount.

Flue Gas Cleaning with Sorbalite

FAQ

During the melting of ferrous scrap, the primary pollutants include sulfur oxides, hydrochloric acid, and hydrofluoric acid, predominantly generated by the combustion of oils and coatings. Additionally, heavy metals such as chromium, nickel, and lead may be released due to the presence of various alloys and contaminants in the materials used. By utilizing Sorbalite, these emissions can be effectively addressed, protecting the environment and complying with the strictest regulatory standards.
Sorbalite is particularly effective in treating various pollutants due to its unique composition. The hydrated lime contained in Sorbalite neutralizes the acids present in the fumes, transforming them into non-harmful salts. Simultaneously, the activated carbon adsorbs and immobilizes heavy metals and other pollutant compounds, significantly contributing to the reduction of atmospheric contamination.
In the purification process of ferrous scrap foundries, Sorbalite is distributed directly into the fumes via a pneumatic injection system. This method allows for immediate and direct contact between Sorbalite and the fumes, facilitating the neutralization of acids and the adsorption of pollutants in a single step.
