# Distillation Designer Skill ## Purpose The Distillation Designer Skill performs distillation column design including tray and packing selection, hydraulic calculations, and column optimization for vapor-liquid separations. ## Capabilities - McCabe-Thiele and Ponchon-Savarit methods - Shortcut design calculations (Fenske, Underwood, Gilliland) - Tray hydraulics (flooding, weeping, entrainment) - Packing selection and sizing (HETP, pressure drop) - Feed location optimization - Reflux ratio optimization - Side draw design - Azeotropic and extractive distillation ## Usage Guidelines ### When to Use - Designing new distillation columns - Rating existing columns - Optimizing column performance - Evaluating tray vs. packing ### Prerequisites - VLE data available - Feed composition defined - Product specifications set - Thermodynamic model validated ### Best Practices - Validate VLE predictions - Consider turndown requirements - Allow for design margins - Evaluate energy integration ## Process Integration This skill integrates with: - Distillation Column Design and Optimization - Separation Sequence Synthesis - Heat Integration Analysis ## Configuration ```yaml distillation-designer: internals: - sieve-trays - valve-trays - structured-packing - random-packing design-methods: - rigorous - shortcut ``` ## Output Artifacts - Column specifications - Tray/packing datasheets - Hydraulic analysis - Operating envelopes - Optimization recommendation...
