Superfractionation is used in the field of petrochemicals to separate isomers with close boiling points.

On top of design experience of such system under their conventional form, Axens can offer its experience of design using heat pump system that is of great interest when the supply of cooling water and steam can be limited or more costly.

Superfractionation often comes in addition to a hydrogenation unit that will have eliminated traces of one component. The optimization of the overall system hydrogenation + superfarctionation may be taken to another level thanks to Axens capability to combine both technologies.
