针对合成氨两台渣油气化炉共用一套氧气放空调节系统，单炉跳车氧气系统压力控制难度大的特点，利用日本横河电机公司CS3000 R3集散控制系统，对单炉跳车情况下的氧气放空进行前馈控制，稳定氧气系统压力，确保另一台气化炉安全稳定运行，减少非计划停车。

Aiming at the fact that in a synthetic ammonia plant , two residual oil gasifiers share an oxygen-ven-ting regulation system and the pressure control of oxygen system becomes difficult in a miss -operation single furnace, the Yokogawa CS3000 R3 DCS was employed to complete feed-forward control so as to stabilize the oxygen pressure and to ensure both safe and stable operation of the another gasifier , as well as to reduce any non-planned shutdown .
