Separation processes thermally sensitive materials

It is proposed to use a distillation system working at about 5mbar to separate thermally sensitive material from crude process material. The distillation system is to be evacuated with a Roots pump (-Sth = 500 m3 h"1) connected to a dry backing pump with a pumping speed of 200 m3h-1. The Roots pump is to be switched on at 50 mbar.

A good example of using adsorptive separation in a non-refining/petrochemical application is the separation of fructose from an aqueous solution of mixed sugars. This process allows the production of high concentration fructose which has a much higher sweetness to calorie ratio than simple glucose or sucrose. As in fine chemical and pharmaceutical applications we can often use adsorption when distillation is not possible or feasible or when the material is thermally sensitive.
