摘要
论述了兰州炼油化工总厂空气压缩站(空压站)空气干燥系统节能技术改造方案及实施情况。空压站安装了大型离心式空气压缩机,其空气净化设备采用大排量连续供风的致冷干燥器和吸附式变周期操作干燥器,净化风露点实现在线连续监测,供风质量符合 GB 4830—84标准,达到了节能和提高空压站效率以及改善操作条件的目的。可供今后工程设计参考。
The modification program for the air drying system in the air compress- ing station of Lanzhou Petroleum Processing and Chemical Complex with emphasis on energy saving and its performance are presented.Several large centrifugal air compressors are in- stalled.Large capacity continuous cryogenic dryer and changing period absorption dryer (ei- ther in series or parallel) are adopted.The dew point of the purified air is continuously moni- tored,the properties of the compressed air meet the requirements of GB 4830—84,and the aim of saving energy,enhancing efficiency and improving operation is realized.This modifica- tion can be referential to the design of new air compressing stations.
