摘　　要：为了研究超音速分离管对Air-CO_(2)混合气体的分离效果,设计并搭建了室内高压超音速旋流分离实验系统。通过HYSYS过程模拟软件和超音速旋流分离等效模型对Air-CO_(2)混合气体脱碳过程进行模拟,并分析了该实验系统的脱碳可行性。结果表明,在现有实验条件下,该系统可以满足超声速分离器的工作要求,将部分CO_(2)气体从Air-CO_(2)混合气体中分离出来。在其他条件不变的情况下,增大超声速分离管入口压力导致入口温度上升,CO_(2)脱除率增加;增大入口CO_(2)摩尔分数导致入口温度下降,CO_(2)脱除率增加。In order to study the separation effect of supersonic separation tube on Air-CO_(2) mixed gas,an indoor experiment system for high-pressure supersonic swirl separation was designed and built.The process of decarbonization of Air-CO_(2) mixed gas was simulated by HYSYS process simulation software and the equivalent model of supersonic swirl separation,and the decarbonization feasibility of the experiment system was analyzed.The results show that under the existing experimental conditions,the system can meet the working requirements of the supersonic separator and separate part of the CO_(2) gas from the Air-CO_(2) mixture.When other conditions remain unchanged,increasing inlet pressure of the supersonic separation tube results in rising inlet temperature and increasing CO_(2) removal rate.The increase of inlet CO_(2) mole fraction leads to the decrease of inlet temperature and the increase of CO_(2) removal rate.
