Corrugated packing for ethylene glycol production columns is a specialized tower packing designed to optimize distillation processes in ethylene glycol manufacturing. Its unique corrugated structure, typically made from materials like stainless steel or plastic, enhances mass transfer and separation efficiency, ensuring high-purity ethylene glycol production with stable column operation.

Key Features and Application in Ethylene Glycol Distillation
These packings are engineered with precise corrugation angles (often 125°/35°) and heights (1–5 meters) to maximize specific surface area (300–500 m²/m³), boosting vapor-liquid contact. Available in materials like 304/316L stainless steel (for high-temperature, corrosive environments) or PP/PVDF (for cost-effective, chemical resistance), they handle the rigorous conditions of ethylene glycol distillation. In production, they are widely used in the rectification section of crude ethylene glycol towers, effectively separating water and organic impurities to achieve product purity above 99.9%, while reducing energy consumption by minimizing pressure drop and improving separation speed.
FAQ:
Q1: What makes corrugated packing superior to traditional random packings in ethylene glycol columns?
A1: Its ordered structure ensures uniform liquid distribution and high gas-liquid contact efficiency, leading to 15–20% lower pressure drop and 10–15% higher separation efficiency compared to random packings.
Q2: What are the standard specifications for ethylene glycol distillation corrugated packing?
A2: Typical specifications include 300–500 m²/m³ specific surface area, 125°/35° corrugation angle, and customizable heights (1–5 m) in metal or plastic materials, tailored to column diameter and production capacity.
Q3: How to select the right corrugated packing for an ethylene glycol production column?
A3: Key factors include required product purity (higher purity needs higher surface area), column operating conditions (temperature, pressure, corrosion), and throughput, with experts recommending material compatibility and manufacturer guidance for optimal results.
