To cope with the current demand for better economic benefits, environmental protection and product slate adjustment, a host of FCC units need to be technically revamped. This article describes the practical processes, technologies and equipment to serve different revamp targets with analysis of two examples on revamp of commercial units.展开更多

The requirements for expanding the CCR unit capacity to 800 kt/a have been met through adopting the low carbon-make PS-VI catalyst, properly lowering the RONC of the reformate, and appropriately retrofitting the towers and furnaces while keeping the reaction system, the catalyst regeneration system and the recycle hydrogen compressor intact. The calibration results have revealed that the liquid yield of reformate products, the octane rating of reformate, the pure hydrogen yield, the aromatics yield and the overall conversion rate all have met the revamp design targets.展开更多

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
