On the basis of the existing equipment, the throughput of this unit has been increased to 800 kt/a from 500 kt/a, with the total liquid yield reaching 88.66%. In the meantime, the revamp has reduced the pressure drop in the regenerator system with apparent energy conservation effects and significant economic benefits.展开更多
