摘要
为了满足日益严格的环保要求,中国石化洛阳分公司于2013年9月16日在2号催化裂化装置上试用国外某公司生产的脱硝助剂,该脱硝助剂由NOxGETTER-NP和NOxGETTER两部分组成,其中NOxGETTER-NP为含Pd双金属助燃剂,NOxGETTER为主剂。工业应用结果表明:在单独加注NOxGETTER-NP、加入NOxGETTER-NP的同时加入NOxGETTER,使主剂分别占总藏量(w)1%和2%的3个阶段期间,加工混合进料的平均氮质量分数分别为3 017.2,2 211.1,1 818.3μg/g。再生催化剂定碳(w)分别比空白标定期低0.003 4,0.008 4,0.009 4百分点,且加注期间助燃效果良好,未发生偏烧、尾燃情况;3个阶段中三旋出口烟气中NOx浓度平均值分别为194.5,97.6,49.7mg/m3,脱硝率分别为58.14%,78.99%,89.30%,脱硝效果显著;脱NOx成本分别为3.4,9.4,18.9元/kg。
The denitrification agents consisted of NOxGETTER-NP and NOxGETTER were applied to FCCU of Luoyang branch, SINOPEC. The NOxGETTER is the base agent with NOxGETTER-NP as a com- bution promoter containg hi-metals including Pd. The nitrogen contents in feeds tested are 3 017.2,2 211.1,1 818. 3 μg/g, respectively. The test is devided into 3 stages： adding NOxGETTER-NP into regenerator alone, and adding NOxGETTER-NP plus NOxGETTER keeping between 1% and 2 % of the inventory, respectively. The carbon content on regenerated catalyst are low of 0. 003 4, 0. 008 4, 0. 009 4 percentage points, respectively for 3 stages, compared with the blank caliberation. The combustion effect is good, no partial burning or tail firing. The average contents of NOx in three export flue gas are 194. 5,97.6,49.7 mg/m3 with denitrification ratios of 58.14%,78.99% and 89.3%, respectively. The effect of denitrification is signifcant and the cost is 3.4,9.4,18.9 RMB/kg, respectively.
