Supports constraint-based explanations of distillation instead of treating the operator as free to select any composition independently.
Ternary product-domain diagrams make the feasibility constraints visible.
Product compositions are constrained simultaneously by thermodynamics, distillation-line geometry, and the overall mass balance. A specified feed and split cannot yield arbitrary distillate and bottom compositions; only combinations inside the feasible product domain are reachable.
