Description:
Nonlinear frequency response (NFR) method, which is an analytical, fast and easy method for evaluating the performance of forced periodically operated chemical reactors, is used for the investigation of possible improvements of a non-isothermal continuous stirred tank reactor (CSTR). A model reaction characterized by a simple reaction mechanism is considered. Inlet concentration and flow-rate are periodically modulated, separately or simultaneously. The product yield is used for evaluating the performance improvements. In Part I of this paper the general non-isothermal case was considered. In this Part II the results are applied to the case of an adiabatic CSTR. For demonstration a laboratory-scale adiabatic CSTR is analyzed applying kinetic parameters for the hydrolysis of acetic acid anhydride. It is shown that improvement can be obtained for simultaneous modulation of the two inputs, with appropriately chosen forcing parameters (frequency, input amplitudes and phase difference).
