1. Absorbers Theory and Design Aleksi Astaptsev Juho Kaljunen

2. Absorption Absorption is a process that refers to the transfer of a gaseous pollutant from a gas phase to a liquid phase. More specifically, in air pollution control, absorption involves the removal of objectionable gaseous pollutants from a process stream by dissolving them in a liquid.

3. Theory Film theory Penetration Theory Surface-Renewal Theory Film-Penetration Theory

4. Design Criteria Exhaust gas characteristics Liquid flow Pressure drop pH Removal of entrained liquid Emmission requirements

5. Sizing: Packed tower Diameter Loading Point Flooding Velocity Height Depends on gas characteristics Solubility of gas: High – Smaller tower Low – Higher tower

6. Sizing: Plate Tower Diameter Small diameter and tray spacing – Fast gas flow - Priming Number of Trays
