摘　　要：NS-17A型结焦抑制剂在兰州石化HS-Ⅱ气液相裂解炉上工业应用,期间HS-Ⅱ裂解炉运行周期由原来45天周期延长至62天,炉管表面温度上升平缓,最高至1051.9℃,低于炉管的烧焦极限值,裂解炉运行稳定。在试验期间,裂解气中乙烯和丙烯的收率有所增加,CO含量稳定,下游急冷器的炉管出口温度维持良好的运行区间。NS-17A type coking inhibitor is industrially applied to the Lanzhou Petrochemical HS-Ⅱ gas-liquid phase cracking furnace.During this period,the HS-Ⅱ cracking furnace is extended from the original 45-day cycle to 60 days.The surface temperature of the furnace tube rises gently,the highest To 1051.9℃,which is lower than the scorch limit of the furnace tube,the cracking furnace runs stably.During the test,the yields of ethylene and propylene in the cracked gas increased,the CO content was stable,and the temperature of the furnace tube outlet of the downstream quench was maintained in a good operating range.
