Pollution Control

Emissions and pollution from industrial processes are areas of intense global focus. Engineers today work on innovative ways to reduce, capture and control many undesirable byproducts. Process industry companies face dual challenges: to reduce environmental impact while creating better products that use less energy. Topics such as green engineering, clean air and water, sustainable design, and carbon reduction have great environmental appeal — and they are at the heart of process engineering, as they drive process optimization and capital investment decisions.

Using a combination of solutions from ANSYS, engineers and designers can simulate the combination of equipment and process parameters across a wide range of applications, for both new product design and retrofit/upgrade scenarios. For example, ANSYS fluid mechanics solutions provide insight and detailed understanding of the formation and dispersion of pollutants (Nox, Sox, mercury, other VOCs) throughout a range of flow problems, including turbulence, chemical reactions, heat and mass transfer, and multiphase flows.

ANSYS solutions can be applied across the industry to pollution and reduction control systems, which includes:

  • Scrubbers
  • Absorbers
  • Precipitators
  • Burners
  • Settling tanks
  • Chlorine contact tanks
  • Wastewater discharge equipment
  • Catalytic converters
  • Cyclones
  • Ventilation devices
  • SCRs
  • SNCRs
