Distillation Engineering & Separation Feasibility
Distillation feasibility depends on separation objectives and mixture properties — column, thermal system and vacuum requirements are reviewed together.
Chemlyst provides assessment and coordination within an agreed project scope. Formal studies, calculations and deliverables depend on available process data and the responsibilities defined with the customer and proposed manufacturing facility. Execution remains with qualified partner facilities unless otherwise agreed.
A. Feed Characterization
- Composition.
- Boiling-point behaviour.
- Relative volatility.
- Thermal stability.
- Potential azeotropic behaviour.
- Presence of solids or fouling components.
B. Column Selection
- Packed versus tray columns.
- Column diameter and height.
- Packing selection.
- Theoretical-stage requirements.
- Pressure-drop considerations.
- Flooding and liquid-distribution considerations.
C. Thermal System
- Reboiler duty.
- Condenser duty.
- Heat-transfer area.
- Heating-medium temperature.
- Cooling-medium requirements.
- Thermal degradation risk.
D. Vacuum Distillation
- Required operating pressure.
- Vacuum-system capacity.
- Air leakage.
- Condensation and vapour handling.
- Pressure-drop effects.
- Receiver and product-handling arrangements.
E. Performance Evaluation
- Product purity.
- Recovery.
- Cut-point selection.
- Residual impurities.
- Batch duration.
- Solvent recovery.
