CHAPTER 3
Separation and Integration
ABSTRACT
Separation sequences can be described by binary, lifted binary and rooted
trees. Dual graded graphs associated with trees generate separation
schemas and highlight the integration methods.
Strategies for separation and integration as fl exible separation operations,
complex distillation configurations, and dual configurations are
presented.
Entropy calculus allows selecting variants of separation and integration
schemas.
