DESULFURIZATION AGENT, AND METHOD FOR DESULFURIZING CEMENT KILN EXTRACTED GAS
To provide: a desulfurization agent obtained by a simple method; and a method for desulfurizing cement kiln extracted gas, by which chlorine bypass exhaust gas exhausted from a chlorine bypass system in a cement kiln facility can be desulfurized with high efficiency in a simple facility which is easily installed on an existing cement kiln facility.SOLUTION: The desulfurization agent includes a cement curing system discarded material having a water content of 10 mass% or more and 55 mass% or less, and a BET specific surface area of 5 m/g or more and 40 m/g or less. The method for desulfurizing cement kiln extracted gas includes extracting part of combustion gas from a kiln exhaust gas flow path in a cement kiln facility, removing chlorine from the extracted gas, and then performing desulfurization. In the method for desulfurizing cement kiln extracted gas, the extracted gas and the desulfurization agent described above are brought into contact with each other, to desulfurize the extracted gas.SELECTED DRAWING: Figure 5
【課題】簡便な方法で得られる脱硫剤、及びセメントキルン設備の塩素バイパスシステムから排出される塩素バイパス排ガスを、既存のセメントキルン設備に付設し易い簡易な設備で、高効率に脱硫することを可能にする、セメントキルン抽気ガスの脱硫方法の提供。【解決手段】水分含有率が１０質量％以上５５質量％以下であり、ＢＥＴ比表面積が５ｍ２／ｇ以上４０ｍ２／ｇ以下であるセメント硬化体系廃材からなる脱硫剤。また、セメントキルン設備におけるキルン排ガス流路から燃焼ガスの一部を抽気し、該抽気ガスから塩素を除去した後に脱硫を行う、セメントキルン抽気ガスの脱硫方法であって、前記抽気ガスと、上記脱硫剤を接触させて、該抽気ガスの脱硫を行うことを特徴とするセメントキルン抽気ガスの脱硫方法。【選択図】図５
