With the addition of Hamon Research-Cottrell (HRC) experts, technologies and experience to our environmental portfolio, B&W has even more options for helping customers reduce emissions and produce cleaner energy.

Background

The former Hamon Research-Cottrell got its start in 1906 when Dr. Frederick Gardner Cottrell, a physical chemistry professor at University of California, Berkeley, proved his invention for precipitating sulfuric acid in a small test unit. He applied and received a patent for his electrostatic precipitator (ESP) design in 1908. In 1912, he and other patent holders from around the world formed The Research Corporation, and the technology has advanced technically and geographically ever since.

Enhanced Product Offerings

Hamon Research-Cottrell environmental technologies enhanceB&W's already-robust portfolio ofadvanced air quality control system (AQCS) technologies and processes, including:

  • Wet and dry electrostatic precipitators
  • Fabric filters
  • Wet flue gas desulfurization (FGD) systems (scrubbers)including a wet gas scrubber specifically designed for oil and gas refineries
  • Spray dryer absorbers (SDA)
  • Circulating dry scrubbers (CDS)

Enhanced Service Offerings

B&W serves as the original equipment manufacturer (OEM) of all Hamon Research-Cottrell environmental products and services. The addition of HRC technologiesalso broadens our experience and installation basefor parts, repairs, upgrades, performance optimization, inspections, maintenance and construction.
