Abstract It is belived that whether the instantaneous objective function curves of plug-flow-reactor (PFR) and continuous-stirred-tank-reactor (CSTR) overlap or not, they have a consistent changing trend for complex reactions ( steady state, isothermal and constant volume). As a result of the relation of the objective functions (selectivity or yield) to the instantaneous objective functions (instantaneous selectivty or instantaneous reaction rate), the optimal reactor network configuration can be determined according to the changing trend of the instantaneous objective function curves. Further, a recent partition strategy for reactor network synthesis based on the instantaneous objective function characteristic curves is proposed by extending the attainable partition strategy from the concentration space to instantaneous objective function-unreacted fraction key reactant space.In this paper, the instantaneous selectivity and several samples are examined to illustrate the proposed method. The comparison with the previous work indicates that it is a very convenient and pratical systematic tool of the reactor network synthesis and seems also promising for overcoming the dimension limit of the attainable rebion partition strategy in the concentration space. |
