Abstract
An integral system and method for the separation and purification in a single operation of a heat or oxygen-sensitive liquid feed, such as a plant derived liquid feed mixture of fatty acids, tocopherol compounds and sterols, into a low boiling point purified fraction of Vitamin E tocopherol compounds and a high boiling point concentrate fraction of triglycerides, which system can be maintained in the presence of an inert gas to provide reduced degradation and increased purity of the Vitamin E fraction. The system includes a pre-evaporator, a vapor-liquid separator, a packed bed distillation column, a rotary thin film evaporator and an evaporator-stripper.
