Separation and IntegrationSeparation and Integration 67
U operates the schemas starting from integrated mixtures towards
compounds that is, from small to a large set of properties allowing
separation. It is the divergent way: S→K1→K2→K3.
D operates the structured schemas from separated compounds to
integrated mixtures. It is the dual convergent way: K3′→K2′→K1′→S′.
The integration request is to make the system as compact as possible,
to couple the exothermic stages to endothermic ones.
The two schemas should be coupled taking into account the fact
that the effect of a separation may be compensated by the effect of the
integration.
