Zusammenfassung: | A system and process for separating a ternary mixture comprising a light key component, a heavy key component, and at least one intermediate key component, wherein said mixture has a distillation boundary on a distillation region diagram that intersects a heterogeneous, minimum boiling binary azeotrope between said intermediate key component and said heavy key component that has a higher boiling point than the light key component, where the system comprises a first stripping zone (12) to separate a portion of said mixture into a first vapor stream (112) and a first product stream (122) enriched in said heavy key component; a second stripping zone (18) configured to separate at least a portion of said mixture into a second vapor stream (120) and a second product stream (126) enriched in said intermediate key component; a rectification zone (14) configured to receive said first vapor stream (112) and said second vapor stream (120) and for separating said first vapor stream and said second vapor stream into a re |
