Reactor Network Synthesis Based on Instantaneous Objective Function Characteristic Curves

Abstract

Abstract: It is believed that whether the instantaneous objective function curves of plug-flow-
reactor (PFR) andcontinuous-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 oryield) to
the instantaneous objective functions (instantaneous selectivity or instantaneous reaction
rate), the optimalreactor network configuration can be determined according to the changing
trend of the instantaneous objectivefunction curves. Further, a recent partition strategy
for the reactor network synthesis based on the instantaneousobjective function
characteristic curves is proposed by extending the attainable region partition strategy
from theconcentration space to the instantaneous objective function-unreacted fraction of
key reactant space. In this paper,the instantaneous objective function is closed to be the
instantaneous selectivity and several samples are examinedto illustrate the proposed
method. The comparison with the previous work indicates it is a very convenient
andpractical systematic tool of the reactor network synthesis and seems also promising for
overcoming the dimensionlimit of the attainable region partition strategy in the
concentration space.
