n efficient algorithm for rigorous dynamic simulation of eactive distillation columns

Anefficient algorithmisdeveloped for solving the systemofdifferential algebraic equations (DAE)describing the dynamics of a reactive distillation (RD) column using the equilibrium tray model. Unlike existing eceived in revised form 23 January 2009 ccepted 27 January 2009 vailable online 4 February 2009 eywords: eactive distillation algorithms, the rate of change of tray specific enthalpy is obtained analytically. This allows direct calculation of the instantaneous vapor rate leaving a tray from the dynamic energy balance. Application to an example methyl acetate RD column shows that the developed algorithm is twice as fast as the algorithm of Jhon and Lee [Jhon, Y. H., & Lee, T. H. (2003).
