![]() In this work, a mass transfer model is proposed for the sieve trays on a pilot scale batch distillation column. One of the most important requirements of the rate-based model is an adequate mass transfer model, whose structure depends on the kind of mixture and the trays/packing geometry. Opposite to the equilibrium model, the rate-based model avoids the use of efficiencies and computes mass and heat transfer rates. One of the mathematical models used to represent the phenomena occurring in distillation is the rate-based model. ![]() Separation occurs on either trayed or packed towers, where simultaneous mass and heat transfer occurs. ![]() Distillation is a well-known separation process, which takes advantage on the differences on the relative volatilities of the components of a given mixture.
