摘要
TUD-DNS3脱硝助剂在中韩(武汉)石油化工有限公司1号催化裂化装置上进行了工业应用。结果表明:针对两段再生工艺,当系统中助剂占总催化剂藏量的质量分数为2.6%时,烟气脱硫装置外排污水中的氨氮质量浓度由加剂前的100 mg/L下降至40 mg/L以内;助剂的加入降低了CO焚烧炉的炉膛温度,有利于烟气的合格排放,并对装置操作、产品分布及汽油、柴油产品质量无不良影响。
The commercial application of denitration additive TUD-DNS3 in FCC unit of SINOPEC-SK(Wuhan)Petrochemical Co.Ltd.was introduced.The results demonstrated that when the mass fraction of this additive accounted for 2.6%of total catalyst inventory,the ammonia nitrogen content in the effluent water of flue gas desulfurization unit reduced from 100 mg/L to less than 40 mg/L;the addition of additive lowered the furnace temperature of CO incinerator,and the emission of flue gas was qualified.No adverse effect on the operation of the plant,the product distribution and the qualities of gasoline and diesel products were found.
