RDNOx-PC2型脱硝助剂在催化裂化装置上的应用分析

Analysis on Application of RDNOx-PC2 Denitration Additive in FCCU

某催化装置3#锅炉进料烟气中CO浓度高(约6.3%)及2#脱硫脱硝废水氨氮偏高,在不影响装置处理量和掺渣量的情况下,通过加注RDNOx-PC2型助剂缓解了上述问题。实践表明加入RDNOx-PC2型助剂后,CO浓度由6.3%下降至4.6%,废水氨氮由>150 mg/L下降至40~60 mg/L。加注助剂期间对装置生产操作未产生不良影响、外排废气达标,取得了较好的应用效果。

In a catalytic cracking unit,the flue gas of boiler No.3 has a high CO concentration(about 6.3%),and the wastewater of No.2 desulfurization and denitrification section has a high ammonia-nitrogen concentration.The above problems are alleviated by adding RDNOx-PC2 additive without affecting the cracking capacity and residue oil blending volume.The analysis in this paper indicates that RDNOx-PC2 additives can effectively reduce the high CO concentration in the flue gas from boiler No.3(from 6.3%to 4.6%),and the high ammonia-nitrogen concentration in the wastewater(from>150 mg/L to 40-60 mg/L).During the operation of adding RDNOx-PC2 additive,there is no adverse effect on the catalytic cracking unit,and the discharge of waste gas is also up to standard,achieving good application results.
