基于DCS大型压缩机控制系统改造及应用

Reformation and Application of the Control System of Large Compressor Based on DCS

随着３．５万ｍ２制氧机组的投产，为了平衡氮气用量，整机迁移一台ＡＴＬＡＳ公司产的 １２ ５００ ｍ３／ｈ氮压机，为便于现场操作、监控，对该制氧机系统的 ＦＯＸＢＯＲＯ公司 Ｉ／Ａ工控机进行了技术改造，保证了氮压机安全、稳定、长周期、低能耗运行。

Oxygen making set of 35 000 m3 was put into operation. In order to balance hydrogen amount, ATLAS made nitrogen compressor of 12 500 m3/h was moved to the workshop equipped with the oxygen making set. FOXBORO made I/A industrial computer of the oxygen making set was improved so as to oper- ate and monitor in situ conveniently, and assure safe, stable, long period and low energy consumption operation of the nitrogen compressor.
