An analytical model of an isothermal flue gas desulfurizationmoving-bed reactor has been developed. The governing equations can beapplied to any moving bed reactor system with pseudo-first order gasphase kinetics. The avarage concentrations of SO_2 in the effluentgas and CuO in the exiting sorbent are provided by explicitequations. The performance of the moving bed reactor can be predictedwith these two simple expressions, thereby eliminating the need fornumerical simulators that model the reactor as an array ofinterconnected microeactors.
