This models the dynamic behaviour of a non-ideal isothermal tubular reactor in order to predict the variation of concentration, with respect to both axial distance along the reactor and flow time. Non ideal flow in the reactor is represented by the axial dispersion model. The analysis is based on a simple, isothermal first order reaction. k a --------> Products The problem involves the two independent variable, time and length. The distance variable can be eliminated by finite differencing the reactor into N equal sized segments (N=8 in this model) of length delZ such that N*delz = L (total length of the reactor). Assumptions The above reaction is assumed to be a first order reaction. Temperature is assumed to be constant. The reactor length is broken into 8 segments here. Thus if the length of reactor is larger than L=10, the user might considering breaking the length into more no. of segments to get a better result and that would imply building in more of the component mass balance blocks.
