Condensation stage
• Condensation of vapors
• Condensation of water steam (prevention of warming or an increase in volume of the washing
solution)
• Condensation of the liquids carried along
Neutralization stage
• Neutralization of acid or alkaline gases
Adsorption stage
• Specific adsorptions and retention of particles (using granules of activated charcoal or a universal
adsorption granulate)
• Recondensation of aerosols
Reaction stage
• Specific reactions (e.g., redox reactions)
