ENERGY CONSERVATION OF THE FLUE GAS EXPANDER OF FCCU

The fine gas expander of FCCU plays an important role in energy conservation of the unit and the refinery as well. On the basis of energy conservation and economic analysis,the estimation of the amount and the benefit of energy conservationl a simple calculating method of dynamic investment return period on the flue gas expander; and the effect and evaluation of the flue gas load rate on power recovery are proposed. The suggested paths for enhancing the power recovery of the flue gas expander are: raising the flue gas inlet temperature; adjusting the CO combustion procedure, increasing the flue gas rate; and heightening the regenerator pressure, etc.
