Regenerative Thermal Oxidizer (RTO)
The Regenerative Thermal Oxidizer (RTO) destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from industrial or manufacturing processes. Anguil RTOs achieve emission destruction through the process of high temperature thermal oxidation, using the proper mix of temperature, residence time, turbulence and oxygen to convert pollutants into carbon dioxide and water vapor.
What makes the RTO the most widely used emission abatement technology is it's ability to repurpose the thermal energy generated during operation to reduce operating costs and energy consumption of the system itself.
How the RTO Works
VOC and HAP laden process gas is either pushed or pulled into the inlet manifold of the oxidizer via a system fan. Flow control or poppet valves then direct this gas into energy recovery chambers where it is preheated. The process gas and contaminants are progressively heated in the ceramic media beds as they move toward the combustion chamber.
Once oxidized in the combustion chamber, the hot purified air releases thermal energy as it passes through the media bed in the outlet flow direction. The outlet bed is heated and the gas is cooled so that the outlet gas temperature is only slightly higher than the process inlet temperature. Poppet valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidizer. The high energy recovery within these oxidizers reduces the auxiliary fuel requirement and saves operating cost. The Anguil oxidizer achieves high destruction efficiency and self-sustaining operation with no auxiliary fuel usage at low concentrations.

Regenerative Catalytic Oxidizer (RCO)
The Anguil Regenerative Catalytic Oxidizer (RCO) destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from industrial processes. The RCO achieves emission destruction through the process of thermal and catalytic oxidation, converting the pollutants to carbon dioxide and water vapor while reusing the thermal energy generated to reduce operating costs.
What differentiates the RCO from a standard regenerative thermal system is the addition of catalyst, it allows destruction of harmful compounds to occur at lower temperatures.
How the RCO Works
Anguil has taken over thirty years of catalyst experience and combined it with a quality Regenerative Thermal Oxidizer (RTO) design, resulting in a system that achieves emission destruction at temperatures 600 to 800 °F (315-427°C) lower than a standard RTO. VOC and HAP laden process gas enters the oxidizer through an inlet manifold to flow control, poppet valves that direct this gas into energy recovery chambers where it is preheated. The process gas and contaminants are progressively heated in the ceramic media beds as they move toward the combustion chamber.
Catalyst placed near the combustion chamber helps oxidize the VOCs and HAPs in an exothermic reaction. Since catalytic oxidation occurs at lower temperatures, a layer of catalyst is used in conjunction with the ceramic packing in an RTO or as a replacement of a portion of the ceramics. As a result, fuel consumption required to preheat incoming emissions could be lowered by 50 to 95 %, further reducing the carbon emissions and operating costs of the already efficient thermal oxidizer. Depending on the process conditions and gas prices, the payback on catalyst costs could be as low as three months when applying this abatement technology.
Hot, purified air releases thermal energy as it passes through the media bed in the outlet flow direction. The outlet bed is heated and the gas is cooled so that the outlet gas temperature is only slightly higher than the process inlet temperature. Poppet valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidizer.
The high energy recovery within these oxidizers reduces the auxiliary fuel requirement and saves operating cost. The Anguil oxidizer achieves high destruction efficiency and self-sustaining operation with no auxiliary fuel usage at low concentrations.

Thermal Recuperative Oxidizer
The Anguil Thermal Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from various industrial processes. The air pollution control device uses the proper mix of temperature, residence time, turbulence and oxygen to achieve destruction or thermal oxidation.
How the Thermal Recuperative Oxidizer Works
The Thermal Oxidizer is designed based on volume of airflow, organic vapor concentrations and desired destruction efficiency. During operation, HAP and VOC laden air is drawn into the system fan and discharged into the inlet where it is preheated in the tube side (typically) of a shell-and-tube style heat exchanger. Contaminated air then passes by the burner where it is raised to the thermal oxidation temperature (1,200-1,800ºF / 650-1,000ºC) for the specified residence time (0.5 - 2.0 seconds) and an exothermic reaction takes place. The pollutants are converted to carbon dioxide, water vapor and heat with within the reactor chamber.
The hot, purified air then passes again through the shell side (typically) of the heat exchanger where the energy released by the reaction is used to preheat the incoming air. The heat exchanger minimizes the system's fuel consumption with the system being self-sustaining at moderate Lower Explosive Limits (LELs). Finally, the contaminant-free air is exhausted into the atmosphere.
Applications which carry silicones may have the configuration reversed, allowing the hot silicone laden air to pass through the tube side of the heat exchanger after the burner for maintenance and cleaning.

Catalytic Recuperative Oxidizer (CATOX)
The Anguil Catalytic Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from industrial processes. The air pollution control device achieves emission destruction at significantly lower temperatures than thermal oxidation through the use of catalyst, converting pollutants to carbon dioxide, water vapor and heat.
How the Catox Works
VOC and HAP laden process gas is either pushed or pulled into a metal heat exchanger inside the oxidizer via a system fan. The contaminated airstream is progressively heated while traveling through the heat exchanger towards the combustion chamber. At the burner, the process gas is raised to the catalyst operating temperature. As the heated gas passes through the catalyst, an exothermic (heat releasing) reaction takes place. The pollutants are converted to carbon dioxide, water vapor and heat.
Once oxidized across the catalyst, the hot, purified air passes through the opposite side of the heat exchanger and releases thermal energy to preheat the incoming air. The heat exchanger reduces the auxiliary fuel requirement, thus saving operating cost, allowing self-sustaining operation with no auxiliary fuel usage at Lower Explosive Limits (LEL) levels of 8-12%. Finally, the cooler, purified air is exhausted to the atmosphere through the system stack.

Direct Fired Thermal Oxidizer (DFTO)
The Anguil Direct Fired Thermal Oxidizer (DFTO) destroys Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds (VOCs) that are discharged from industrial or chemical process exhausts. The DFTO achieves destruction of pollutants by the process of combustion. VOCs and HAPs are oxidized to carbon dioxide and water vapor with the proper combination of temperature, residence time and turbulence within the combustion chamber.
The DFTO is an ideal abatement technology for process streams heavily laden with pollutants and intermittent batch processes where the oxidizer can come on-line relatively quickly.
How the Direct Fired Thermal Oxidizer Works
Sometimes referred to as an Afterburner, Enclosed Flare or Vapor Combustor the direct fired thermal oxidizer uses a specially designed burner to raise the temperature of a pollutant laden air stream to a predetermined combustion temperature. In operation, the contaminated process exhaust is ducted into a burner chamber. Heat applied by the burner oxidizes the VOCs and HAPs creating harmless products of combustion (water and carbon dioxide). The clean, heated exhaust gas can then be discharged to the atmosphere or sent through an optional heat recovery system.
The Anguil DFTO can achieve over 99% hydrocarbon destruction rate efficiency. To achieve this the heated air is kept in the combustion chamber for a specified amount of time, called the residence or dwell time. At the inlet to the combustion chamber turbulence is generated to mix the pollutants and oxygen molecules. Proper mixing of the combustion air and process streams not only provides high destruction efficiencies but also safe operation. The Anguil design minimizes the risk of explosion and takes complete advantage of the VOC laden exhaust stream to minimize auxiliary fuel needs. An optional burner system is available to burn inert process streams directly in the burner as fuel.
From a small tank vent to the largest of ethanol plant applications, each Anguil DFTO is designed around our customer's application. Special designs can be provided to handle process streams that contain acids such as carbonic, hydrochloric or sulfuric acid.

Vapor Combustor Unit (VCU)
Thermal flaring technologies used for the destruction of Hydrocarbons, Volatile Organic Compounds (VOCs) or Hazardous Air Pollutants (HAPs) are designed in two basic configurations; open and enclosed flame burners. Recent regulations on visible emissions, vapor radiation, Greenhouse Gases (GHGs) and noise pollution have driven industry away from open flaring and towards the enclosed vapor combustion system.
To meet this demand, Anguil has developed an enclosed vapor combustion system that combines the simplicity of an enclosed flare with the destruction performance of a thermal oxidizer. Whether designed for intermittent use or installed on a continuous emission stream; the Anguil Vapor Combustor (AVC) technology has many advantages over other enclosed combustion systems. It is a robust device capable of handling varying emission flow rates and concentration changes.
Commonly utilized on low volume - high concentration vapors, the applicability of these fume incinerators is broad. They are utilized in a variety of process industries for off-gas treatment but most notably applied in the chemical, petrochemical, oil and natural gas industries on mixing operations, tank vents, loading stations and more. Facilities with high emission destruction requirements and low maintenance demands should consider the vapor combustor as a viable option for compliance.
How the Anguil Vapor Combustor Works:
Prior to the introduction of process gases, a purge sequence within the AVC is initiated to remove any existing combustibles from the device. The pilot ignites only after the system controls confirm a safe condition. The process gas is introduced to the system through an isolation valve or inlet duct. It is these process emissions which then begin fueling the combustion device.
Anguil Vapor Combustor InstallationAnguil’s standard vapor combustion unit is designed in a natural draft configuration, negating the need for combustion air fans. A blower package may be necessary under low process pressure conditions but in most cases, combustion air is drawn into the destruction chamber via one or more natural-draft air inlets. Modulating control dampers automatically provide the temperature control that ensures proper combustion temperatures for the oxidation of the various compounds.
For highly variable process conditions, both in terms of flow and hydrocarbon content, the emissions may be introduced to the combustion chamber through a number of different burner heads or stages. Staged introduction of process gases result in higher system turndown ratios and lower Greenhouse Gas (GHG) emissions like NOX and CO2. This stable, staged combustion burner also allows emission destruction to occur at low operating temperatures; typically between 1,500 and 1,800 °F (815 and 982 °C).
During operation, destruction of process gases in the combustion chamber is generally achieved through an exothermic reaction as opposed to endothermic where supplemental fuel is required to reach destruction temperatures. The natural gas burner is only used for supplemental firing to maintain operating temperature and emission destruction during low process gas conditions. With the proper mix of time, temperature and turbulence, the AVC typically sees destruction efficiencies upwards of 99+%.

Each product line represents value-engineered systems with emphasis on cost minimization. All systems are designed for seamless integration into the process, optimal performance and trouble-free operation.
Rotor Concentrator
Typical air pollution control projects focus on the capture mechanism and a destruction device. With regulations driving towards higher capture efficiencies, combustion devices must treat larger volumes of air with lower concentration of pollutants.
The Anguil concentrator is an adsorption system designed to concentrate large volume, low concentration process exhaust into a much smaller, highly concentrated air stream. The greatly reduced flow is rich in emissions when sent to a thermal or catalytic oxidizer. The destruction device can then be much smaller in size and utilizes the steady stream of emissions to fuel combustion of incoming contaminants.
Typical applications include but are not limited to large paint systems, Permanent Total Enclosure (PTE) exhaust and styrene emissions.
How the Emission Concentrator Works
The high volume, low concentration airstream passes through a rotor wheel or cartridge style concentrator where emissions are stripped from the air and adsorbed onto the substrate. The majority (approximately 90% of the total air volume) of this clean air is then exhausted to atmosphere. A small portion of the air stream (approximately 10% of the total air volume) is heated to an elevated temperature to be used as desorption air.
The concentrator rotates continuously, transporting adsorbed toxins into a desorption section. In the desorption section, the organics are desorbed from the adsorptive media with the low volume heated airstream. This low volume, high emission-laden air is then processed by an oxidizer.
The concentrator with integrated oxidizer is often the most cost effective technology for processing high volume, low concentration streams. While the capital cost of a system is competitive with other technologies, the true savings is realized in reduced operating costs. When couple with a concentrator, an oxidizer will operate with very little additional natural gas consumption. At higher concentration values, it even has sufficient "free energy" to provide adsorption energy for the concentrator.
