摘要:

延迟焦化装置小比例掺炼催化澄清油,可以解决油浆出路问题。独山子石化1.2 Mt/a延迟焦化装置实验结果表明:①小比例掺炼催化油浆澄清油对焦化装置的换热影响较小；②蜡油收率、焦炭收率略上升,干气及各液体收率略下降；③未对焦炭质量和工艺操作造成影响；④掺炼后未造成加热炉炉管结焦趋势增加,也没有造成设备损坏；⑤掺炼催化油浆后,每年经济效益达到1 328万元,表明小比例掺炼催化油浆具有可行性。 

Abstract:

Catalytic clarification oil can be blended in the delayed coking device with small proportion to solve the problem of oil slurry outlet. The experimental results of Dushanzi petrochemical 1.2 Mt/a delayed coking device showed that:①it had minor effect of small proportion of blending catalytic oil slurry on heat exchange of the coking unit; ②the yield of wax oil and coke slightly increased, dry gas and the liquid yield slightly decreased; ③it had no effect on coke quality and process operation; ④the coking trend of heating furnace tube didn’t increase after blending, and it also didn’t cause the damage of equipment; ⑤the economic benefit reached 1 328×10⁴ RMB yuan per year after blending catalytic oil slurry, which showed it was feasible for blending catalytic oil slurry with small proportion.
