Design of Packed Columns - The Engineering Concepts

WebPacked columns are smaller than trayed columns. Because of this difference, packed and tray columns are referred to as continuous-contact and staged-contact columns. 6 General Design Considerations The design of a distillation column is often divided into two parts: a mechanical design and a process design. WebJul 25, 2024 · Packed columns are used for distillation, gas absorption and liquid-liquid extraction. The gas-liquid contact in a packed column is continuous (or say Rate wise approach ), not stage-wise, as in a plate column. The liquid flows down in the column over a packing surface and the vapor (or the gas) moves counter-currently, up the column.
