Implication

Review evaluates integrated multi-pollutant technologies and advanced sorbents across industrial flue gas systems, highlighting pathways toward cost-effective simultaneous emission control.

Key Points

  • Evaluate conventional and emerging technologies alongside advanced sorbent materials to identify effective, integrated approaches for the simultaneous removal of multiple gas-phase air pollutants from industrial flue gas.
  • Synthesized technical evidence from laboratory to industrial-scale applications of wet and dry scrubbing, integrated treatment units, catalytic processes, and novel adsorption methods.
  • Compared major sorbent classes—including calcium-based, carbon-based, catalytic, zeolites, metal-organic frameworks, and nanomaterials—based on target pollutant combinations, operating temperatures, and regeneration performance.
  • Integrated multi-pollutant systems substantially lower capital costs, process complexity, and equipment footprints compared to conventional single-pollutant treatment trains.
  • Porous sorbents including metal-organic frameworks and zeolites demonstrate superior simultaneous removal efficiencies for complex gas streams, though thermal stability and scalable regeneration remain primary deployment constraints.
