摘要
以催化外甩油浆为对象,在1.8×106t/a重油催化裂化装置上开发了外甩油浆微型旋流净化工业实验装置,考察了微型旋流芯管压力、分离效率和流量的相互关系,确定了微型旋流芯管净化催化油浆的最佳操作条件。结果表明,随着入口流量的增加,分离效率提高,而压力降增大。在进口流量为250～260l/h、进口催化剂颗粒平均粒径为3.5μm的条件下,分离效率在45.77%～82.80%,将催化剂的回收效率从原来静电分离设备的10%～20%提高到50%～80%。
An industrial sidetrack tester of residual oil separation by mini-hydrocyclone in 1.8×10^6 t/a catalytic cracking unit was set up, in which the slurry from the heavy oil catalytic cracking was taken as the separation object. The relationship of pressure, separation efficiency and inlet flow rate of mini-hydrocyclone was studied. With the rose of inlet flow rate, separation efficiency increased, while pressure drop increased. Under the condition that inlet flow rate was ranging from 250 to 260 1/h and the average diameter of catalyst particles at inlet was 3.5 μm, the separation efficiency was 45. 77%- 82.80%. The recycle ratio of catalyst particles was increased from 10%-20% by electrostatic catalyst separator to 50%-80%.
