Hamon Research Cottrell

Hamon Research-Cottrell: more than a century of expertise in Air Quality Systems

Hamon Research-Cottrell began when Dr. Frederick Gardner Cottrell invented the first industrial electrostatic precipitator in 1907. To support scientific research, Dr. Cottrell co-founded the non-profit Research Corporation in 1912. Forty years later, Research Corporation gave birth to Research-Cottrell.

Since that time, Hamon Research Cottrell has been a leading supplier of pollution control technologies worldwide. With a multitude of product offerings including:

    • Dry Electrostatic Precipitators (DESP)
    • Wet Electrostatic Precipitators (WESP)
    • Fabric Filters
    • ExxonMobil Wet Gas Scrubbers
    • ReACT™ multi-pollutant control technology
    • Urea to Ammonia (U2A®) Systems
    • Dry and Wet Flue Gas Desulfurization Systems (FGDS)
    • DeNOx Systems (Selective Non-Catalytic Reduction SNCR)

 

Aftermarket Services

Repair and Maintenance

  • Inspection, troubleshooting, performance analysis, training
  • Repair supervision, emergency repairs, outage maintenance

 

Parts and Customer Service

  • Discharge electrode wires and weights
  • Rigid discharge electrodes
  • Collecting plates
  • Transformer rectifiers (Single / 3-phase)
  • Insulators (support, through, standoff)
  • Filter bags and cages
  • DeNOx Catalyst
  • Microprocessor control systems, electrical and mechanical auxiliaries

 

Upgrade, rebuild, life extension, and performance enhancement

Hundreds of systems have been modified to meet more stringent performance requirements. Units built in the 1960s and 70s can often be modified to provide 15 to 20% more collecting surface without increasing their footprint.

 

Other innovative solutions exist, amongst others:

  • Ash conditioning – SO3 and/or Ammonia
  • Retrofit/conversion of ESP into FF
  • Addition of a new ESP or FF in parallel
  • Conversion from tumbling hammer to MIGITM rappers.
  • Optimization of electrical system, e.g. T-R controls, microprocessor upgrades, DCS remote communication and monitoring, increased sectionalization
  • Enlargement by additional fields, additional gas passages, height, etc.
  • Gas flow optimization through CFD and physical modeling
