SOURCES OF POLLUTION IN SIDERURGY AND TECHNIQUES FOR REDUCING NOXIOUS EMISSIONS
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The systematic identification of the various sources of pollution creates the necessary background for organizing actions in order to prevent and fight against pollution. The diversity of the sources and forms of pollution are characteristic of industrial activities, especially of those in the chemical industry, metallurgical engineering, transportation industry, generally, industrial sectors dealing with raw material manufacturing. In the metallurgical industry, the air pollution takes place especially on the basis of the following categories of polluting agents: solid particles resulted from powders, particles drawn by combustion gases, particles of coal, ore, coke and fusing agents, slag, iron oxides, sulphur oxides (SO2 and SO3), nitrogen oxides (NO2 and NO3) and, although in smaller quantities, by tars, hydrocarbons, soot, organic acids and others. Being familiar with the sources of pollution, their monitoring and control represent a first step towards reducing the quantity and the toxicity of all emissions, focusing on applying a “cleaner” production in the industry of elaborating and processing metallic materials, too. This paper succinctly presents the main sources of pollution in the primary siderurgical sectors, as well as a series of techniques to reduce pollution, especially in the process of steel elaboration.
