With increasing nitrogen purity, PSA plants require an over-proportional air demand with the consequence that high-purity PSA systems engender a distinct interest in energy-saving measures. This paper presents process intensification strategies with the focus on a reduced energy consumption. Therefore, the influence of PSA configuration and cycle organisation on process performance was investigated. Results are presented at two product purity levels (10 ppm/1000 ppm O₂) and two operating temperatures (25 °C/45 °C) in a lab-scale twin bed PSA (2 × 2 L). It is shown that dedicated strategies are available to intensify the PSA process; however, their effects are dependent on ambient conditions and product purity levels.

随着氮气纯度的提高，PSA工厂对空气的需求过高，结果导致高纯度PSA系统对节能措施产生了浓厚的兴趣。本文介绍了以降低能耗为重点的过程强化策略。因此，研究了PSA配置和周期组织对过程性能的影响。在实验室规模的单人床PSA（2×2 L）中，结果以两种产品纯度水平（10 ppm / 1000 ppm O ₂）和两种操作温度（25°C / 45°C）给出。结果表明，有专门的策略可以加强PSA流程。但是，它们的影响取决于环境条件和产品纯度水平。
