摘要
The invention concerns a process for recovering power in a fluid catalytic cracking unit used particularly for the treatment of heavy charges, wherein at least a portion of the power available in the gas flows withdrawn from two catalyst regenerators (4) and (21) of a fluid bed catalytic cracking unit are recovered.PP According to the invention the fumes from regenerator (4) are fed to one of the stages of a turbine (35), the pressure in this stage being lower than the pressure of the fumes from regenerator (4) and the fumes from regenerator (21) (whose pressure is lower than that prevailing in the first regenerator (4)) are fed to another stage of the same turbine (35) whose pressure is lower than that of the stage to which the fumes of regenerator (4) are supplied.
