The Most Cost Effective Gas Cleaning Device in Steel Industry with Industrial Ecology Approach

Industrial growth and environmental damages, as two important indicators in sustainable development are followed by steel industry. This article leads industries to green industry. In this case, energy, material, capital consumption and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for different furnace tonnages. In this way total cost in 3 mentioned dust collectors were calculated in four furnaces with capability of 1, 3, 6 and 12 tonnages. The results indicated that venturi scrubber dust collector for 3-ton and less capability furnaces was the most suitable option in terms of environmental sustainability and industrial ecology. But for the capacities beyond 3 tons, the usage of bag filters and electrostatic precipitator dust collectors were more suitable.
