Column sizing is a fundamental aspect of column design. In our design the PB column uses a Sulzer 125Y packing with a specific surface area of 116 m2/m3 and a void fraction of 0.988. An example of the development of new distribution technologies for floating installation of a reactive absorption column is also presented. Design of plate column for absorption and distillation involves many common steps of calculation such as determination of number of theoretical plates, column diameter, plate hydraulic design, etc.In absorption process, a soluble component is absorbed in a liquid (called solvent) from a gaseous mixture. absorption purposes: Packed column Plate column 5.4 COMPARISON BETWEEN PACKED AND PLATE COLUMN 1) The packed column provides continuous contact between vapors and liquid phases while the plate column brings the two phases into contact on stage wise basis. • Either plate or packed towers may be used when the column diameter is between 1.5-4.5 ft (or area, 1.77- 15.9 ft2).
