原闭路RO(CCRO)的能量学可以通过增加往复活塞缸来改进,该往复活塞缸的尺寸在操作期间不能在真实的时间内调节,从而限制活塞的最大冲程长度。在这项工作中,实际与理想的比例上的改进CRO的性能的气缸尺寸的影响进行了分析。如果钢瓶尺寸过小,则CC过滤步骤可以从原始CCR0开始并过渡到改进的CCR0。如果尺寸过大,则仅实施改进的CCRO,而CC过滤和冲洗时间延长。对于这项工作中研究的超高回收率应用,使用时空模型,将气缸尺寸缩小70%或过大50%显示出2%或更少的额外能耗,证实了其操作灵活性。
The energetics of the original Closed-Circuit RO (CCRO) may be improved by adding a reciprocating-piston cylinder whose size may not be adjusted in real time during operation, thus limiting the maximum stroke length of the piston. In this work, the effect of the actual-to-ideal ratio of cylinder sizing on the performance of the improved CCRO is analyzed. If the cylinder is under-sized, the CC filtration step may start with the original CCRO and transition to the improved CCRO. If over-sized, only the improved CCRO is implemented, while the CC filtration and flushing periods are extended. For ultra-high recovery applications studied in this work, under-sizing the cylinder by 70 % or over-sizing by 50 % revealed a 2 % or less extra energy consumption using a spatiotemporal model, confirming its operational flexibility.
