Aluminum Recycling Foundry. Solutions for Flue Gas Cleaning

Companies specializing in aluminum recovery operate in the recycling of cans, tins, profiles, and processing waste, transforming them into usable material. During the remelting process of these recovered materials, hazardous compounds are released into the environment, including sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), and heavy metals such as copper, magnesium, silicon, zinc, and manganese. To reduce the emission of these harmful components, it is essential to use a flue gas purification system capable of neutralizing acids and retaining heavy metals. This is achieved through an advanced multi-stage filtration system that uses special chemical reagents, selected in compliance with the environmental regulations in force in the area where the company is located.

FAQ

How is the disposal of fumes produced by foundries in the aluminum recovery process handled?

Aluminum Recovery Foundries focus on converting aluminum scrap, such as cans, tins, profiles, and processing residues, into reusable materials. The melting process of these recycled materials reaches very high temperatures, enough to release harmful substances contained in the scrap, including Sulfur Oxides (SOx), Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and for the vaporization of heavy metals such as Copper, Magnesium, Silicon, Zinc, and Manganese. Therefore, it's necessary to adopt an efficient filtration system to remove the acidic agents and trap the heavy metals. This measure is crucial for protecting the environment and the health of communities surrounding the facilities, as well as for complying with current environmental regulations. For this purpose, a sophisticated multi-stage filtration system that utilizes specific chemical reagents is used. Some of these reagents have basic properties that neutralize the acids, creating salts as byproducts, while other reagents combine with heavy metals, preventing their dispersion in the air.

What pollutants are emitted during the melting process for aluminum recovery?

During the melting process for aluminum recovery, pollutants such as Sulfur Oxides (SOx), Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and heavy metals such as Copper, Magnesium, Silicon, Zinc, and Manganese are released from recycled material and drawn up with exhaust fumes into the plant's ducts. A filtration system is required to prevent these substances from being released into the environment, preventing harm to the health of people as well.
