摘要
国内外最新的研究工作表明 ,在液液萃取、液气比很大的吸收和高压精馏的情况下 ,应用散装填料的操作性能优于规整填料和塔盘。其中扁环填料具有独特的结构和优异性能。本文介绍了从阶梯短环到超级扁环的发展过程、技术特点和在合成氨气体净化中的应用。
It is shown from the recent research,the random packing has better performance than other column internals for liquid liquid extraction,absorption with high liquid loading and high pressure distillation.Especially,the SMR has elaborate design and excellent performance.Therefore,the development of the SMR from Cascade Mini Ring(CMR)is described and the characteristics and application of SMR for synthetic ammonia plant is introduced.
