碳捕集与储存（CCS）系统中二氧化碳压缩机技术的研究进展

摘要

Carbon dioxide from industrial emission has caused many serious climate and environmental problems. Carbon Capture and storage (CCS) system is a possible way to control the emission of large amounts of carbon dioxide. But its features are high cost and low efficiency at present, especially the cost of compressing carbon dioxide is relatively high. Therefore, to improve the CCS system’ s cost-effectiveness, the performance and technology of carbon-dioxide gas compressor should be improved. In the paper, the research progress of CFD’s application in traditional compressor design is firstly introduced, and then the two important developing technologies of carbon-dioxide gas compressor are reviewed. The analysis and comparison are given.%　　当今，工业排放的二氧化碳温室气体所造成的气候及环境问题越来越严重。碳捕集与储存（CCS）系统的开发为控制碳的大量排放提供了可能性。但目前CCS系统成本较高，效率较低，尤其是压缩二氧化碳成本较大。可见改善二氧化碳压缩机性能及技术将是提高CCS系统成本效益的有效途径。论文首先介绍了CFD技术在传统压缩机性能改进及优化方面的研究进展，然后较详细地介绍了两种新型二氧化碳压缩技术的研究进展情况，并进行了分析比较。
