摘要
中国石油大庆炼化分公司MIP-CGP装置为控制再生烟气NO_x排放,与中国石化石油化工科学研究院和中国石化催化剂分公司合作,进行了降低烟气NO_x排放功能的新型CGP-1DQ专用催化剂的工业应用试验。结果表明:在新型催化剂占系统藏量约40%时,再生烟气NO_x排放降低到约656mg/m^3,相对试用过程中断阶段NO_x排放最高值(1 134mg/m^3),降低幅度为42%;相对以往空白阶段的峰值(1 900mg/m^3),降低幅度达到65%以上。此外,新型催化剂的使用对裂化产物分布无不利影响,装置保持平稳运行。
To reduce NOx emission on MIP-CGP unit in CNPC Daqing refinery,a commercial trial of a novel specially formulated catalyst CGP-1DQ with the function of NOx emission reduction was per- formed. The results show that when the new CGP-1DQ in catalyst inventory reaches about 40%, NOx emission in flue gas is decreased by 42 % to about 656 mg/m^3 compared with the level of NOx emission （1 134 mg/m^3） in the interrupted period during the trail. However,if compared with the base condition （1 900 mg/m^3）, NOx emission is decreased by more than 65 %. In addition, no negative influence on product distribution and unit running are observed during the operation.
