PSA technology is applied to the separation and recovery of carbon dioxide and carbon monoxide from blast furnace gas in steel works. Through the laboratory PSA experiment, the effect of cycle time and carbon dioxide concentration in blast furnace gas are revealed. Demonstration plant, which had the capacity of 3 tons of carbon dioxide per day, was constructed and operated in various separation conditions. It was found that increase in carbon dioxide recovery leads decrease in power consumption of vacuum pump. From temperature change and its distribution in both vertical and horizontal direction, which indicated adsorption and desorption behavior of carbon dioxide, scale up to the enormous PSA system was discussed.
