Usability of Structured Packings
Download as PPTX, PDF0 likes253 views
The document discusses structured packing for distillation and absorption columns. It describes how the geometry, surface treatment, and manipulated variables of structured packing can be modified to increase column efficiency. It also lists some typical low pressure, low irrigation applications for structured packing like vacuum fractionation and atmospheric crude oil fractionation. Finally, it notes that using high quality structured packings can increase product yield and purity while reducing reflux ratios, pressure drop, and liquid hold up.

Usability of Structured Packings
- 1. Ensures Feasible Extraction in Distillation and Absorption Column
- 2. Crimp height Crimp inclination angle Element height Surface treatment Fouling tendency System properties and service The packing of the material can be modified in term of packing geometry, surface treatment, and manipulation of the variable used as per the requirement to increase the efficiency of the extraction column.
- 3. Structured Packing is usually involved in low pressure and low irrigation rate applications. It is commonly used in columns like Typical applications include Vacuum Fractionation Atmospheric Crude Oil Fractionation FCC Main Fractionator
- 4. Carbon steel Stainless steel alloys Aluminum Titanium Nickel alloys Copper alloys Zirconium
- 5. The high quality Structured Packings will bring increase product yield, enhance product quality/purity, increased heat transfer across the column, and also lead to reduced reflux ratios, lower pressure drop, reduced liquid hold up.
