are the industry standard for removing pollutants from hot gas streams because they provide maximum surface area for gas-liquid contact while minimizing pressure drop. Designing a scrubber for high-temperature applications requires careful thermodynamic and aerodynamic balancing to avoid structural failure, solvent boiling, or poor absorption efficiency.
