| 摘 要： | 基于碳分子筛动态吸附机理,建立了分离氧氩的实验装置.实验研究了流程形式、清洗比、吸附时间对碳分子筛分离氧氩过程性能的影响.结果表明,循环过程中增加产品气清洗阶段可以显著提高解吸气的纯度.为了得到质量分数为99.0%以上的氧气,循环过程中清洗比应控制在0.4左右,最佳吸附时间为60 s.以95%氧、5%氩的混合气作为原料气,实验装置的产品气纯度可以达到99.4%,氧气回收率为42%. |

| Abstract: | The experimental apparatus for the separation of oxygen and argon was established based on the kinetic adsorption of carbon molecular sieves. The effects of PSA cycle, rinse-ratio and adsorption duration on the performance of adsorption processes were investigated. The experimental results show that to incorporate the rinse step can increase greatly the concentration of oxygen in desorbed gas. For producing high purity oxygen, the optimum values of the rinse-ratio and adsorption duration should be about 0.4 and 60 s respectively. Under this condition, the oxygen purity up to 99.4% is obtained for the 42% recovery with the feed gas mixture of 95% oxygen and 5% argon. |
| Keywords: | carbon molecular sieve separation of oxygen and argon PSA rinse-ratio high purity oxygen |
