催化裂化装置高效汽提器技术的工业应用

COMMERCIAL APPLICATION OF HIGH EFFICIENCY STRIPPER IN FCCU

中国石化股份有限公司荆门分公司 0 .8Mt/a重油催化裂化装置应用洛阳石油化工工程公司设备研究所的专利技术 ,将原反应沉降汽提器改造成高效汽提器。工业应用结果表明 :在汽提蒸汽量下降 16 %的情况下 ,待生催化剂上焦炭的氢碳比值 (H/C)同比降低了 43 % ;再生器烧焦量同比下降了 1个百分点 ,每年可少烧焦 80 0 0t,年经济效益 85 0× 10 4RMB

Using the patent technique of Equipment Research Institute,LPEC, the stripper was revamped into high efficiency one in the 800 000 t/yr RFCCU of Jingmen Company,China Petroleum and Chemical Corporation.Commercial results showed that the hydrogen/carbon(H/C) ratio of coke on spent catalyst decreased by 43%,coke combustion amount decreased by 1 percent point despite 16% decrease of the amount of stripping steam.The annual coke burning amount decreased by 8 000t,and the economic benefits reached 1 024×10 4 RMB$.
