Corrugated packing is a key component in pharmaceutical solvent recovery, acting as core internals in distillation columns to separate and purify solvents efficiently. Its structured design boosts mass transfer, ensuring high recovery rates and strict compliance with pharmaceutical purity requirements.

Design and Performance Advantages
Pharmaceutical-grade corrugated packing, typically crafted from corrosion-resistant materials like 316L stainless steel or polypropylene, features precise wave angles and uniform spacing. This design maximizes vapor-liquid contact, reducing channeling and dead zones. For example, 250Y or 350Y mesh/ plate corrugated packing, with specific surface areas of 250-500 m²/m³, enables efficient separation of solvents such as ethanol, isopropyl alcohol, and ethyl acetate. In antibiotic production, it improves recovery yields by 15-20% compared to random packings, while maintaining product purity within USP/EP limits.
FAQ:
Q1: What makes pharmaceutical corrugated packing different from standard industrial packing?
A1: It adheres to strict GMP standards, uses medical-grade materials (e.g., 316L SS), and has tighter dimensional tolerances to prevent contamination, critical for pharmaceutical-grade solvent recovery.
Q2: How does corrugated packing affect distillation column pressure drop?
A2: Its structured flow path results in 30-50% lower pressure drop than random packings, reducing energy consumption and extending equipment lifespan.
Q3: Can corrugated packing be reused after cleaning in pharmaceutical processes?
A3: Yes, with proper cleaning (e.g., dilute acid/alkaline washes per SOPs), it can be reused multiple times, minimizing waste and operational costs.
