Parti Bazlı Distilasyon Tesisleri

Parti bazlı distilasyon oldukça esnektir ve tipik olarak küçük ve orta ölçekli kapasiteler için kullanılır. Daha büyük üniteler için devamlı distilasyon tesisleri daha enerji-etkin ve ekonomiktir.

Two operational modes are possible for the batch process:

1. In  the batch distillation with a fixed reflux ratio, the compounds are separated according to a defined product specific time schedule. This is based on the components´ boiling ranges , that lead to a fractionation of the different components: beginning with the light boilers and ending with the heavies. The classical application is the fractionation of multi-component–mixtures.
2. The batch distillation with a varying reflux ratio allows the distillation at a constant distillate concentration; it is applied where a distillate with constant physical behaviour needs to be obtained.
