The air from the Granulators and the Coolers contains urea dust that is entrapped in Hamon’s scrubbers. In these industrially proven impact type scrubbers, efficiencies are very high and dust concentrations lower than 20 mg/Nm3 can be achieved at the stack outlet. The total amount of urea collected by these scrubbers is recycled, for reconcentration, to the process.The same process is used to capture NH3 from the gases at the outlet of the Fertilizer Industry.

ReACT™ (Regenerative Activated Coke Technology) is an advanced multipollutant technology that achieves simultaneous capture of SOx, NOx and mercury in one vessel.The process was first developed in the 1970s in Germany, was subsequently advanced and commercialized in Japan where ReACT™ has been implemented at three large scale coal-fired power plants and at several steel mill and refinery applications:The 321-MW Wisconsin Public Service Weston Power Plant, Unit 3 is equipped with a ReACT™ system engineered and supplied by Hamon Research-Cottrell.Hamon Research Cottrell offers ReACT™ under a license agreement from J-Power Entech.

Besides primary measures, Selective Catalytic Reduction (SCR) is the most effective method for controlling nitrogen oxide emissions (NOx) from combustion sources. It is a commercially proven flue gas treatment technology that has been demonstrated to remove over 98 percent of the NOx contained in combustion system exhaust gas. The catalyst is at the heart of the SCR process. It creates a surface for reacting the NOx and ammonia, and allows for the reaction to occur within typical flue gas temperature ranges.Hamon uses a similar technology to reduce also VOC or CO content.Thorough knowledge in the design of all types of heat recovery systems including heat exchangers made of glass or fluoroplastic tubes to de-saturate the flue gas downstream a wet scrubbing system allows for minimum energy consumption when the flue gas needs to be heated.

Hamon Research-Cottrell provides process and equipment expertise, drawn from more than fifteen years of experience with the patented Urea to Ammonia U2A® technology, starting from bench and pilot scale, through systems for small gas turbine SCR and the largest utility scale SCR systems for coal and gas fired boilers.Hamon Research-Cottrell’s U2A® system provides several benefits:Urea as feedstock eliminates the hazards associated with the transport, transfer and storage of toxic anhydrous or aqueous ammonia.Compared with using 19% aqueous ammonia, energy use is reduced.Process control response provides ammonia on demand, easily following load conditions.Hamon Research-Cottrell offers U2A® on a worldwide basis and has installations in Europe and the Middle East in addition to a large installed base in the United States.

Selective Non-Catalytic Reduction is a post-combustion technology that is designed to control nitrogen oxides (NOx) emissions from boilers by the injection of ammonia or urea reagents into the flue gas.Hamon Research-Cottrell is licensed by Exxon Mobil for the application of ammonia based Thermal DeNox™ (TDN).

Using standardized material and equip­ment, having a compact design which reduces freight and installation costs, requesting a minimal space envelope, dedicated to the industry, placed as a stand alone or in a modularized assembly, the Hamon Fabric Filter is easy to install and operate. It meets the stringent efficiency requirements mandated by today’s environmental regulations.Products series allow selection for: a wide range of air volumes from 1000 to 45000 m³/h per unit, treat gas from ambient temperature to 200°C, , remove particulates load up to 30 grams/Nm3, ensuring emission efficiency up to 5 mg/Nm3

The Hybrid Collector is the combination of an Electrostatic Precipitator (ESP) with a Hamon Fabric Filter with suitable air to cloth ratio. In a Hybrid Collector, the fabric filter is located either downstream of the ESP or within the casing of the existing ESP by replacing one or more fields of collecting plates with the fabric filter modules. The Hybrid collector can help bring particulate emissions into compliance due to the fabric filter collecting higher levels of particulate, and finer particulate, than an ESP of an equivalent footprint

Hamon fabric filter systems are a major component of a long tradition of excellence. We combine more than 40 years of experience in fabric filtration including the latest approaches in low pressure high volume pulse jet filters as well as more conventional technologies such as medium pressure pulse jet filtration.Our engineers have designed and constructed fabric filters for a variety of applications, including cement, coal fired steam generators, stoker fired boilers, fluidized bed combustion boilers, municipal waste incinerators, cogeneration facilities, and industrial processes such as steel, rock products, aluminum, etc.A fabric filter system is very effective at the collection of fine particulates and metals. By using the appropriate fabric filter design (reactor type) and with additional sorbents injection upstream the fabric filter, air toxics such as SOx, mercury, dioxine,can be collected with substantially high efficiency.
