Grain coal


Combines a mixture of physical and chemical processes to control gas emissions. Oxidized gases are converted into harmless products such as CO2, water and salts. It is designed to eliminate efficiently pollutants such as acidic gases, N- and S- containing compounds and low molecular weight compounds. Brings improved physical properties such as hardness and resisrance against fully saturated atmospheres. Its exhaustion is easily seen since the colour changes from violet to brownish.
