Heat and mass transfer models of the University of Tennessee at Chattanooga distillation column

The distillation column in the University of Tennessee at Chattanooga is a Pyrex glass unit with 12 separation stages, overhead receiver and a reboiler as shown on figure 8. In this thesis, mathematical models that relate to heat and mass transfer during a binary distillation of methanol-water mixture are developed and simulated through analytical and numerical methods [1]. Collections of these models were generated from theoretical correlations which yielded algebraic and differential equations that were solvable simultaneously. [2]. Thermal transfer due to temperature gradient caused heat flux through conduction, convection, and radiation respectively [3]. These heat transfer equations facilitated approximations of the reboiler surface temperature during heating and cooling processes. Mass transfer was considered during the binary distillation process; where dynamic and steady state mass transfer models were derived from methanol component’s mole balance. An average relative volatility of 4.0 for the methanol water mixture promoted reparability and mass transfer during the experimental and modeling processes. [3].
