Packed column design
WebPacked towers are used increasingly in small fractionating towers and absorbers where access is restricted. Their use is also advantageous where corrosion control is essential. Because of liquid-distribution concerns, packing still is usually not recommended for large-diameter columns, or where a high turndown ratio is required.

WebGeneral Information. Packed bed reactors consist of a cylindrical shell with convex heads. Most are vertical and allow reactants to flow by gravity. Inside the reactor is an immobilized, or fixed, bed of catalyst. Packed bed reactors are heterogeneous reaction systems. The picture below shows an apparatus used to study flow through a packed column. Web6. Packed columns are more suitable for handling foaming systems. 7. The pressure drop can be lower in a packed column than the equivalent plate column. The design procedure of a packed column consists of the following steps: 1. Select the type and size of packing. 2. Determine the column height required for the specified separation. 3.
