| 中文摘要: |
| 针对钢铁工业烟气成分复杂、排放量大且处理难的问题,分析各碳捕集技术特点、发展现状以及未来趋势。目前,吸收法是最成熟、最适合的碳捕集方法,在工业上已出现商业化应用。新型碳捕集技术在碳捕集方面有很大潜力,但大多都处于实验室规模的开发,未来这方面是一项巨大挑战。以膜接触器为代表的复合捕集技术破单一捕集技术瓶颈,已出现应用在燃煤工业上。未来在实际过程中,要根据钢铁各工序烟气特点及浓度差异选择不同的捕集方法并对钢铁工业碳捕集技术进行了展望。 |
| 英文摘要: |
| Aiming at the problems of complex flue gas composition, large emissions and difficult treatment in the iron and steel industry, the characteristics, development status and future trend of each carbon capture technology were analyzed. At present, the absorption method is the most mature and suitable carbon capture method, and it has been commercially applied in the industry. New carbon capture technologies have great potential for carbon capture, but most of them are being developed at laboratory scale, which is a huge challenge in the future. The composite capture technology represented by the membrane contactor breaks the bottleneck of single capture technology and has been applied in the coal-fired industry. In the future, in the actual process, different capture methods should be selected according to the characteristics and concentration differences of flue gas in each process of steel, and the carbon capture technology of the steel industry is prospected. |
