Abstract

Abstract: Using fixed-bed reaction method， the influence of blast furnace top gas composition on HCl removal by low temperature Ca-based antichlor under none-dust and with-dust conditions was studied through changing individual variable of the gas composition. The results showed that when the content of CO₂ in blast furnace top gas increased， the dechlorination efficiency decreased under both none-dust and with-dust conditions. However， when the content of CO and N₂ increased， the dechlorination efficiency improved substantially under both none-dust and with-dust conditions. It was also found that the dechlorination’s breakthrough time was 40~60min more than that under none-dust condition， while the capacity of reacted-chlorine increased 6% under with-dust one.

Key words: blast furnace top gas, HCl gas, dechlorination agent, breakthrough time, capacity of reacted-chlorine
