The stable operation of the circulating water supply and auxiliary system of the air separation plant is crucial to the supply of oxygen,nitrogen and argon media.Based on the ECS-700 control system,the index requirements of the circulating water system,the principle of self-cleaning filters and other ancillary facilities,as well as the modification of the control of the water system are introduced.Through the modification of the logic control system,the traditional production operation mode relying on manual on-site operation has been changed,the working mode and the automatic control of the program when the circulat-ing water system works in the fault state has been described with emphasis.
