Despite improvements in theoretical calculations it is still required to measure phase equilibria in industry research and development and science.
As a result, the PILODIST®-vapour-liquid-equilibrium apparatus belongs to the standard equipment in chemical engineering laboratories.
The vapour-liquid equilibria of binary and multi-component mixtures are an important basis for the determination of the separation efficiency. The required number of “theoretical plates” can be determined with this system. Although a lot of dates have been published it is required to re-determine equilibria data because thermodynamic parameters like pressure, temperature and concentrations are different or inadequate.
