Tellerette packing Ceramic tellerette packing is important in improving this process.
Gas-Liquid Interaction Mechanisms
The gas increases and touches the falling of liquid in the tower, forming interactions between the gases and liquid.
During mass transfer, solvent vapors are transferred between gases and liquids depending on the surface area and the contact time.
Interaction is augmented by packing materials.
Ceramic tellerettes form small surfaces and turbulence which enhance the mixing of gases and liquids.
This accelerates the rate of diffusion and uptake of solvent in liquid.
Solvency Recovery Significance
Solvents such as NMP are important to recover and a good amount of mass transfer is necessary to regulate the extent of the solvent being stripped or absorbed.
Low contact contributes to high costs and emissions of wasted solvent.
