  1. Column Packing

  2. Introduction In all column systems, packing's can provide optimal performance only when complemented properly designed tower distributors, collectors, supports, and other columns internals for optimum liquid-vapor distribution to the packed beds. Columns are used for distillation, gas absorption and liquid-liquid extraction. The gas-liquid contact of the packed column is continuous as in the case of a column, not stopped. The liquid flows into the column over the packing surface and the stream moves. www.finepacindia.in

  3. Factors Of Packed Column • Vacuum system: Low Pressure Drop • Small Diameter Column • Corrosive System • Foaming • Lower Liquid Hold-Up • Distillation www.finepacindia.in

  4. Column Packing Design Procedures • Select packing type and size • Determine the column height for the specified separation • Determine the column diameter (capacity). To process liquid and vapor flows • Select and design the internal functions of the column: packing support, liquid distributor, redistributors, dispenser plates for extraction columns. www.finepacindia.in

  5. Objectives Of Packing Design • The distillation column is operated at a steady reflux ratio. • Perform the mass balance calculation in the distillation column. • Performance Comparison of Packaging and Tray Column for Distillation Process. www.finepacindia.in

  6. Properties Of Packing • High surface area per volume • The pressure drop should be a desirable low level. www.finepacindia.in

  7. Packing Material • Ceramic: - High wettability, corrosion resistance at high temperature, optimal strength • Metals: - Excellent strength and excellent wetting • Plastics: - They are inexpensive and have excellent strength, but they are less wettability at low liquid velocities. www.finepacindia.in

  8. Advantages Of Packed Column • The column packing is more suitable for handling the foaming system. • Packed columns are generally cheaper than equivalent plate columns • It is always difficult to install plates and packed columns should be considered for small diameters • Low pressure drop than tray columns • Pickingscan be manufactured for column diameter above 25 mm • Lower capital, operating and maintenance costs • Simple structure • Corrosive solvents can be handled by corrosion resistant packaging materials • It has better mass transfer than spray columns www.finepacindia.in

  9. Types Of Column Packing • Random Packing:- Random packing is the packing of a specific geometric shape that is discarded and randomly oriented in a tower. • Structured Packing:- Structured packed offers 30% capacities higher than random packed for equal efficiency up to 50% higher at the same capacity. • Grid Packing:- Systematically placed packings use an open lattice structure. The device consists of panels that promote mass transfer and improve tear removal. www.finepacindia.in
