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 99.99%.

Depending on the industry, the following terms may be used interchangeably to describe the vapor combustor technology: Low Emission Flare (LEF), Medium Temperature Flare (MTF), High Temperature Flare (HTF), Industrial Burners, Enclosed Flares, Biogas Flares, Gas Burners, Fired Heaters, Open Flame Flare, Candlestick Flare, Flare Stack, Thermal Combustors, Fire Box, Enclosed Burners, Vapor Combustor Units (VCUs).

The Anguil system is simply named AVC.  It is a straight-forward acronym for a robust device, capable of handling varying process flow rates and vapor concentration changes.  From emergency venting applications to steady stream off-gas treatment, Anguil has a custom solution for every application that offers safety, reliability and versatility.

The Anguil Advantage:

  • Proprietary Bruner Design Eliminates Visible Emissions and the need for Water / Steam Injection
  • Air Staging Burner Design Further Reduces NOX and CO Output
  • Skid Mounted Design Simplifies Installation and Reduces Costs

Operating Cost Reduction Strategies:

These waste-stream destruction devices are also ideal for process fluid heating needs.  Sometimes referred to as a process fired heater, the AVC can be equipped with heat transfer tubes in the combustion chamber to capture waste heat and use it for other process heating needs.
