Air Quality Systems

Integrated Solutions for a clean Environment

Hamon the EPC Solution since 1904

As an International Engineering, Procurement and Contracting Company (EPC) having also Manufacturing capabilities, Hamon is a worldwide player in the following Industries: • Power Generation • Oil, Gas & Petrochemical Industries • Iron and Steel, Cement, Glass, Incinerators and other Heavy Industries.

Achille Hamon and his brother, Fernand, were both engineers and they owned a company that worked and assembled projects in wood. In 1904, Achille created a company in France, and in 1906, Fernand did the same in Belgium. Both companies produced the cooling towers required for the new industrial processes. As it turned out, this was perfect timing as the industrial revolution needed ways to treat the water that came from the mines, the steel works, and the new electric power stations.

All along the century that followed, the Hamon Group developed its activities abroad, with important milestones in the USA, Germany, Australia, South Africa and many others. This has led, through acquisitions and implementations, to a Group having today a worldwide presence, across the 5 continents.

In parallel, the scope of technologies has been developed so as to offer, today, a complete range of solutions that improve the impact of heavy industries on our environment. This enables numerous clients across the globe to produce cleaner energy and maintain air quality.

Hamon’s innovatory solutions apply to the supply of equipment and services for:

The reputation of Hamon takes also its origin in the acquisition of world-famous Companies and brands:  Research-Cottrell  Enviroserv  Deltak  Thermal Transfer Corporation  Custodis  D’Hondt Heat Recovery - Steam Generators Waste Heat Boilers

Hamon

Air Quality Systems Hamon Environmental : More than a century of expertise 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.

Hamon Environmental continues, through acquisitions in the nineties, the tradition of engineering excellence by designing, building, and servicing top class Air Quality Systems for the Power generation, the Heavy Industries and the Waste to Energy Plants.

Mission Reducing emissions is a mandatory and complex task for any industry. The result must not only comply with present and future regulatory requirements, it must also integrate the needs of specific production processes, schedules and budget constraints.

Hamon Environmental has decades of experience in the design, engineering, construction, start-up, operation and maintenance of Air Quality Systems. In order to test and optimize our designs and continuous technological improvements, we conduct our own in-house flow dynamic models and computer simulations.

This expertise, which includes countless in situ emission control systems for numerous and varied processes, allows us to confidently apply technology to any specific requirement.

Every of our employees is committed and proud to work for a better environment.

Dust Removal Systems Electrostatic Precipitators For more than a century, on the basis of Dr. Frederick Gardner Cottrell’s patent through Research-Cottrell company, Electrostatic Precipitators (ESP’s) have been the preferred Air Quality Control Technology for particulate abatement in power generation and industrial processes throughout the world.

ESPs can be designed to meet stringent particulate emission standards with minimal pressure loss and high equipment reliability for extended plant operation.

Hamon has an installed base of over 5000 ESPs in numerous industries Hamon provides a full range of equipment for dry electrostatic precipitators, including preassembled and panel type collecting plates, durable rigid discharge electrodes, mechanical tumbling hammers or electromagnetic rapping devices and a full range of microprocessor controls.

Fabric Filters 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 reverse gas filtration or medium pressure pulse jet filtration.

Our engineers have designed and constructed fabric filters for a variety of applications, including 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, glass and cement. With inherent high collection efficiency, a fabric filter system is very effective to collect fine particulates and heavy metals.

Hamon offers a wide variety of filter bag cleaning technologies and associated fabric filter media to suit virtually all operating conditions and dust characteristics.

With additional dry sorbents, air toxics such as mercury, dioxins and furans can be collected with substantially reduced injection rates of sorbents compared to ESP’s.

Additionally when installed as the particulate collection device following spray dryer or circulating fluid bed dry Flue Gas Desulfurization - FGD systems, additional SO2 capture takes place across the filter cake deposited on the fabric which enhances the total SO2 reduction across the system and at lower reagent consumption rates over a Dry Flue Gas Desulfurization - DFGD and ESP system.

Hybrid Collectors The COHPAC™ (Compact Hybrid Particulate Collector) is the combination of an existing or new electrostatic precipitator with a Hamon fabric filter with suitable air to cloth ratio.

The fabric filter is located in a separate casing downstream of the ESP or within the existing ESP’s casing by replacing one or more fields of collecting plates with fabric filter modules.

The technology is based on the fact that a fabric filter collects higher levels of particulate - and finer particulate - than an ESP of equivalent footprint. The bag house acts as a «polishing device» which can bring particulate emissions into compliance at very low levels and offers an optimal site for injection of sorbents such as activated carbon for mercury control.

Acid Gas Removal Systems Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide (SO2) contained in gases produced by the combustion of fossil fuels such as coal, oil, orimulsion, municipal solid waste, automobile tires and many industrial processes such as gasoline refining, cement, paper, glass, steel, iron, and copper production. Sulfur dioxide emissions are a primary contributor to acid rains and have been regulated by every industrialized nation in the world.

Worldwide, Hamon FGD systems are treating over 65,000 MWs of power generation capacity in twenty countries and on many more industrial class applications.

Hamon is expert in designing and supplying: • Dry Sorbent Direct Injection Systems • Circulating Fluidized Bed Scrubber • Semi-Dry systems, with Rotary Atomizers or Spray Nozzles • Wet Systems with Lime or Limestone • Sea Water Desulphurization • Wet Gas Scrubber (Refinery, Exxon Mobil licence)

Lime or Sodium (Bi)carbonate Dry Injection Lime Circulated Fluidized Bed Semi-dry Scrubber Lime or Limestone Wet Scrubber Sea Water Desulfurization ExxonMobile Wet Gas Scrubber™

The total Solution for all Pollutants

These Systems are divided in 3 categories:

Dry Scrubbing, by injection of dry lime or sodium bicarbonate, to control acid gas emissions primarily from combustion sources such as utility and industrial boilers, municipal and medical waste incinerators or industrial processes such as glass furnaces.

In Semi-Dry Scrubbing, the flue gases are introduced into an absorbing tower (dryer) where the gases are contacted with a finely atomized alkaline slurry : usually a calcium based sorbent such as Ca(OH)2 or CaO. Acid gases are adsorbed by the slurry droplets and react to form solid salts. The heat of the flue gas is used to evaporate all the water droplets, with a non-saturated (i.e. dry) flue gas leaving the absorber tower.

The effect of cooling and humidifying the hot gas stream increases collection efficiency over simple dry injection.

Wet scrubbers are gas cleaning equipment where the dirty gas stream is brought into contact with a scrubbing liquid.

The scrubber design depends on the industrial process conditions and the nature of the air pollutants involved. Wet scrubbers can be designed to collect particulates and/or gaseous pollutants by capturing particles in liquid droplets and by dissolving pollutant gases into the liquid.

Hamon and ExxonMobil Research & Engineering Company (EMRE) have an exclusive licensing agreement to provide Wet Gas Scrubber and Purge Treatment Unit as an air pollution control technology for Refinery Fluidized Catalytic Cracking Units (FCCU).

NOx Removal Systems

SCR 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.

Urea to Ammonia (U2A) SCR NOx removal process requires ammonia, either anhydrous or aqueous, which is a toxic substance. The hazards from exposure vary from minor discomfort to toxic poisoning and asphyxiation. To counter this risk and ensure the safety of plant personnel and the surrounding community, Hamon offers a patented on site Urea-to-Ammonia generation system, U2A™, that produces ammonia by a method avoiding the hazards of its transportation, transfer, and storage.

In addition, there are economic benefits versus using unregulated lower concentrations of aqueous ammonia.

Selective Catalytic Reduction Selective Non-Catalytic Reduction CO catalytic Oxidation Urea to Ammonia U2A™

Multi-Pollutants & Special Applications ReACT™ (Regenerative Activated Coke Technology) This revolutionary Process controls SO2, NOx, Hg and particulates in a multistage regenerative process that produces sellable by-product. It is applicable to Utility and Industrial Processes, including Sinter Plants, Incineration, RFCC and Coal Fired Boilers.

The J-Power 2 x 600 MW coal fired Isogo plant near Yokohoma (Japan) is the world’s lowest emissions intensity power plant with SO2 and NOx emissions both at single digit ppm concentration levels.

Combined Flue Gas Treatment Systems for Dioxins & Heavy Metals Control Waste incineration is probably the most severely demanding application for the Flue Gas Cleaning field. Control of several pollutants such as SOx, HCl, HF, heavy metals, dioxins and furans, as well as NOx, must be accomplished with integrated air quality systems that combine different treatments to provide the highest efficiency of removal in respect of the best available technology. Hamon excels in providing custom made installations to respond to the most severe conditions.

Urea Scrubbers for the Fertilizer Industry 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.

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 Optimization of electrical system, e.g. T-R controls Enlargement by additional fields, additional gas passages, height, etc

Research & Development Data Reconciliation More than a century of data collection is used on a daily basis to benchmark mathematical calculation against reality. Hamon’s expertise therefore increases every day, enabling its empirical surveys to cope with the everchanging regulation environment. In addition, designs are continuously improved and, consequently, offer the optimum solution for every specific case.

CFD (Computational Fluid Dynamics) Modelling Mathematical models enable Scientists and Engineers to carry out numerical tests in a virtual laboratory. Our 3-phase and 3-dimensional systems are modelling physical laws through mathematical equations (Euler & Lagrange) and enable to determine optimal flow configurations for all types of requirements.

In particular, nozzle arrangements, baffles, packings and other internals are scrutinized so the overall efficiency of the system is optimized.

An example of Applied Research: Conversion of ESP into FF When regulations change the emission levels or when capacities need to be increased, or both, existing ESP’s can be modifi ed by changing part or whole of their internals by a Fabric Filter arrangement.

Since most of the existing Equipment (casing, hoppers, supporting structure, ash handling system,…) is reused, this operation represents a substantial saving in cost and footprint and requires a minimum downtime period.
