酸性水汽提装置产生的高含氨酸性气的处理

介绍了中国石化金陵分公司硫磺回收装置的工艺技术特点。概述了硫磺回收装置处理含氨酸性气、氨氧化焚烧的机理，结合热反应炉氨氧化焚烧过程的三要素，对影响装置氨焚烧效果的因素进行了分析。详细总结了硫磺回收装置处理高含氨酸性气的氨焚烧实际运行过程中存在的问题及采取的对策和措施。在硫磺回收装置处理高含氨酸性气的氨焚烧过程中积累了一定的成功经验，装置的安全稳定长周期运行能够得到保证，装置SO2排放浓度下降到424 ㎎/m3以下，可持续达标；装置NOx排放浓度控制在55 ㎎/m3以下。

STUDY ON TECHNOLOGY PROCESS OF TREATING ACID GAS INCLUDING HIGH AMMONIA IN SULFUR RECOVERY UNIT

This paper presents the technique features of sulfur recovery unit in Sinopec Jinling petrochemical company. Based on brief introduction of principle of acid gas treatment and ammonia incineration, the three main factors which affect ammonia burning in oven were analyzed in detail. The problems in the ammonia bearing gas treatment in 50kt/a sulfur recovery unit and possible countermeasures were discussed. Some of practical technical solutions and experiences for long stable operation of treating the ammonia bearing acid gas were also introduced. By above countermeasures, SO2 emission is decreased to 424 mg/m3, friendly to environment. The NOx emission can be effectively controlled to less than 55 mg/m3.
