1.2.3 Mc Cabe Thiele Labelling

When using the McCabe-Thiele method, the enthalpy balance must be taken into account.

The McCabe-Thiele method assumes a constant composition of the liquid flow existing on each separation stage. This composition is the same as the composition of the feed.

In the McCabe-Thiele method, an adiabatic system is assumed.

When using the McCabe-Thiele method, the molar enthalpy of each phase flow remains constant along the separation device.

The McCabe-Thiele method assumes a thermodynamic equilibrium of the outging phase flows of each separation stage.

The McCabe-Thiele method takes occurring pressure losses from separation stage to separation stage into account.

The McCabe-Thiele method is a short-cut method for determining the number of theoretical separation stages.

For the use of the McCabe-Thiele method the liquid and vapor phase flows are assumed to be constant along the column.

The enthalpy of mixing of the compounds must be taken into account when using the McCabe-Thiele method.

The McCabe-Thiele method assumes identical latent heats (evaporation or condensation enthalpy) of both compounds.
