1.2.3 Mc Cabe Thiele Labelling

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

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

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.

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

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

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

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

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

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.
