3S智能喷雾系统在延迟焦化装置的应用

中国石化塔河炼化有限责任公司利用3S智能喷雾系统对2号延迟焦化装置焦炭塔大吹汽系统进行了改造。改造后:大吹汽期间蒸汽用量由改造前的8 t/h降低到3~5 t/h,减小了大吹汽期间蒸汽管网的波动;每塔每次蒸汽用量由20 t降低到8.93 t,节约大吹汽蒸汽55%以上;工艺参数均保持正常,焦炭质量合格,挥发分质量分数在9%左右,每塔可回炼三泥10 t左右。达到了降低延迟焦化装置能耗、保护环境的目的。

Energy-saving revamping of delayed coking unit with 3S system

The steam flushing system of the coke drum of 2# delayed coking unit in SINOPEC Tahe Petrochemical Co.,Ltd.was revamped with 3S system.After revamping,the steam consumption in flushing was reduced to 3 ～5 t/hr from 8 t/hr before the revamping and the fluctuation of steam piping network was minimized.The steam consumption for each drum was reduced to 8.9 t from 20 t and steam saving was over 55 ％.In addition,the process parameters remained normal,the coke quality met the specifications and volatile mater was controlled at about 9％.About 10 tons of sludges could be recycled for each coke drum.The energy consumption of the delayed coking unit was reduced,and the purpose of protecting the environment was achieved.
