 The TTPL has experimental capabilities that involve:

-     Low pressure VLE measurements,

-          Determination of the solubility of solids in liquids

-          Determination of the solubility of solids/liquids in supercritical CO2

-          80-tray distillation column and air/steam stripping,

-          Supercritical fluid extraction bench scale unit,

-          Pilot unit for separation of polymer mixtures and

-     Pilot plant unit for membrane technology applications (ultrafiltration, reverse osmosis etc).

Application to separation processes involves both conventional approaches (distillation -fractional and extractive- and liquid-liquid extraction) as well as non-conventional methods such as supercritical fluid extraction.
