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。
The latest research work at home and abroad shows that in the case of liquid-liquid extraction, large liquid-gas absorption and high-pressure rectification, the operation performance of bulk packing is better than regular packing and tray. One flat ring packing has a unique structure and excellent performance. This article describes the development from the short ladder to the super flat ring, its technical features and its application in the purification of ammonia gas.
