Absorption columns strip unwanted gases from air or process streams. They work by mixing a gas flow with a liquid solvent that grabs the target compound. Clean gas exits the top. Rich liquid leaves the bottom for recovery or disposal.
Packed towers suit most jobs. They use random or structured packing to spread liquid and boost contact time. Plate columns handle high liquid loads and dirty feeds better—each tray acts like a mini stage. Material choice depends on your chemistry. Carbon steel works for neutral streams. Stainless fights corrosion. Glass-lined or exotic alloys tackle harsh acids and high temps.
Key specs to nail: height gives you stages and removal rates; diameter sets gas velocity and flooding limits. A column too short misses targets. One too narrow floods and chokes flow. Pilot testing beats guesswork every time.
FAQ: How do I pick between packing and trays? Use packing for low pressure drop and foaming systems. Pick trays when you need high turndown or have solids in the feed.
