摘要
本文介绍了金陵石化公司炼油厂设备研究所研制的催化裂化新型靶式进料喷嘴以及与 Y 型高效进料喷嘴工业对比试验结果。靶式喷嘴结构独特,油流冲击靶面,经蒸汽雾化从喷嘴喷出,形成连续的扇面油雾层,与上升的催化剂充分接触。试验结果表明,用于馏分油催化裂化进料可提高轻油总收率0.52%,降低焦炭产率0.28%(对原料),经济效益明显。新型靶式进料喷嘴进料雾化效果好,操作弹性大,能适应原料日趋重质化的需要,可避免结焦堵塞。油嘴、汽嘴和靶子等更换方便,可以大大减轻检修工人的劳动强度。
A novel target-type feed nozzle for FCC unit developed by the Refinery
of Jinling Petrochemical Corporation,as well as its commercial test in compa-
rison with the high efficiency Y-type feed nozzle is presented.The target-
type nozzle is novel in structure.The flowing feedstock lashes at a target
plane and is then atomized by steam.The mist thus formed is ejected thro-
ugh the jet tip into the reactor and comes into close contact with the up-
flowing catalyst particles.The commercial test results showed that the light
oil yield was increased by 0.52% and the coke yield was reduced by 0.28%
based on the waxy distillate feedstock.The economic benefit was obvious.This
target-type feed nozzle is also suitable for heavy oil feedstocks.It is flexible
in operation and avoids the problem of jet tip blockage caused by coking.Its
parts,such as the oil snout,steam snout and the target,can be easily cha-
nged and thus lessens the labour intensity of maintenance work.
