Resumo

DRY BLAST FURNACE GAS CLEANING TECHNOLOGY OFFERS GREAT ECONOMIC ADVANTAGES WHEN COMPARED TO TRADITIONAL WET GAS CLEANING OWING TO ITS IMPROVED ENERGY EFFICIENCY, LOWER COST, REDUCED PLOT SPACE, AND PRACTICALLY ELIMINATED WATER CONSUMPTION. GIVEN THE IMPROVED OPERATIONAL ECONOMICS AND – IN SOME AREAS – THE PHYSICAL OR ECONOMIC SCARCITY OF WATER, STEEL PRODUCERS ARE SHIFTING TOWARDS THE APPLICATION OF DRY BLAST FURNACE GAS CLEANING SYSTEMS, IN WHICH THE WET SCRUBBER IS REPLACED WITH A DRY SECONDARY GAS TREATMENT STAGE. THE DANIELI CORUS SOLUTION IS BASED UPON PROVEN TECHNOLOGY THAT HAS BEEN APPLIED NUMEROUS TIMES FOR CLEANING ALUMINUM SMELTER GASES AND ANODE BAKING FUMES. THE SYSTEM CONSISTS OF A GAS CONDITIONING TOWER, REAGENT INJECTION SYSTEM AND (PRESSURIZED) FILTER MODULES WITH LOW PRESSURE PULSE CLEANING. CURRENTLY, DANIELI CORUS IS IMPLEMENTING THIS TECHNOLOGY FOR THREE GREENFIELD BLAST FURNACES IN INDIA. THIS ARTICLE PRESENTS THE ADVANTAGES OF THE PROVEN TECHNOLOGY AS WELL AS SOME IMPROVEMENTS THAT WILL BE APPLIED DURING THE ONGOING PROJECTS. THESE IMPROVEMENTS INCLUDE STEAM REHEAT OF (COLD) BLAST FURNACE GAS, SINGLE PHASE WATER INJECTION IN THE CONDITIONING TOWER AND TWO STAGE COUNTERCURRENT ABSORBENT INJECTION.
