HCl emission control

Solutions for evaluating and reducing hydrogenchlorid (HCl) emissions

air pollution control


A base-line emissions audit by FLSmidth includes:

  • on-site stack testing
  • process analysis and
  • raw material sampling

These results are analyzed by process specialists who provide a report that compares current emissions levels against current or future limits, identifies the sources of any emission problems, and recommends practical and economical solutions.


FLSmidth's gas suspension absorber, the FLS® GSA is a flexible multi-pollutant control system that provides more than 90% HCl removal. Its small footprint makes it ideal for retrofit projects.

Our Hydrated Lime Injection (HLI) technology captures HCl and other pollutants by injecting hydrated lime into the flue gas in the duct leading to the dust filter.
