B&W strengthens environmental offerings with Hamon Research-Cottrell emissions control technologies
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.
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 enhance B&W’s already-robust portfolio of advanced 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 technologies also broadens our experience and installation base for parts, repairs, upgrades, performance optimization, inspections, maintenance and construction.
