Utility flares (DU series) are one of the most common flare designs use for applications with no smokeless burning requirements. They are also utilized in applications where smokeless flaring can be achieved without the use of an additional assist medium.

To dispose of heavy waste gases, which have a greater tendency to smoke, in a smokeless manner, we provide three different design options, depending on customer requirements. Air Assisted Flares, which utilize forced air from blower(s) to provide assist air for combustion and promotes additional air entrain from the ambient due to the relatively high exit speed of the streams. Steam Assisted Flares based upon the injection of medium pressure steam at tip level, using peripheral steam rings (SA model), center steam spargers, and/or inner induction tubes (SAI model).

Pressure Assisted Flares: Mach 1 sonic / Start fire / SN / Variable slot VMSA. Our cutting-edge MACH-1 sonic flaring technology, suitable for both off-shore and onshore installations, utilizes high pressure flare gas to establish an exit velocity equal to the speed of sound to combust waste gas smokelessly.

Our Titan Demountable Flares, also named demountable derricks, are derrick-supported flares with three, or four leg configurations and overall heights of up to 200 meters. Designed to accommodate several risers/tips on the same derrick structure. Each flare tip has its own set of pilots. The demountable system allows maintenance at grade on each flare tip while keeping the other flare systems in operation. Fixed derricks are also available within our portfolio.

We design and supply Multipoint Ground Flares (MPGF) when very large flows are required to be flared in an array enclosed configuration. This system is characterized by multiple stages, with first stage(s) provided with assist support such as gas, air, steam for high smokeless performance at low regimes, and the upper stages coming into operation depending on the header pressure and the flaring need with their smokeless operation attained by pressure. Each stage is composed of runners and burners. In some cases, the number of burners can be of up to 500 burners spaced properly to promote cross light and reduce the number of pilot burners. The flames are shielded by fence panels supported by structural frames in the range of 15-20 meters tall. The staging skids are designed with an actuated staging valve and a safety element such as rupture disk, buckling pin valve, total relief valve, etc.

We design Enclosed ground flares when waste gases are requested to be flared in an enclosed stack, with reduced flame visibility, minimal heat and noise, emissions sampling, ease, and smokeless combustion, in sensitive areas. The stack is internally refractory lined, designed for low and medium flows, has high destruction efficiencies relative to an open flare and designed as natural draft or forced draft systems. Operated with control louvers and dampers which are optional, or air blowers, respectively.

The Pit Flare (or “Burn Pit”) is usually constructed of an excavation lined with a non-combustible lining of rock or refractory material. Often coupled with a pit liner, our pit flares can be a cost-effective combustion option for an environmentally conscious user. Our high efficiency burner produces a mixture of vapor and liquid from a single source. While most often designed to operate nonsmokeless, through use of AEREON`s various Pit Flare technologies (Chimera, Peackock, Triton), smokeless operation can often be achieved.

Our Peacock Oil Burners are designed to flare liquid hydrocarbons without liquid fallout or soot formation. These burners provide excellent service for well testing operations. When only oil is flared, a high-pressure air or gas source is required to provide additional mechanical atomization to ensure the mixture is a fine mist when it exits the burner nozzle which is designed to accept separate high-pressure oil and air/gas streams. If the waste stream is an oil/gas mixture, a “spider” burner will be installed instead of the atomizing burner nozzle. Chimera and Triton are other models available.

All our Pilot Burners are fuel efficient pilots, self inspirated type, characterized by their durability, reliability, and ease of installation (retractable). Available models are ignited via FFG - flame front generator system (model 245), or HEI - high energy Ignition System HEI (model 250) or combined FFG and HEI (model 255). They can be retractable from ground level (model 270 retrax), and function without support gas (model 100 Continuum). The CONTINUUM Ignitor allows a flare to function without a pilot utilizing the flare gas itself as pilot gas and a continuum sparking system which generates a spark every 20 seconds for 2 seconds duration.

We design Knockout Drums (KO Drums) in both horizontal and vertical configurations, as gas-liquid separators with high efficiency of separation of liquid droplets, with maximum size in the range 300-600 microns. We also supply Liquid Seal Drums, including all accessories: anti-pulsation device, siphon, level control, liquid make-up, and instrumentation. These systems are designed for the protection of the upstream flare header against flashbacks/explosions, in the event of purge loss, withstanding a certain degree of vacuum upstream of the drum without seal break. Typical of hot flaring or low molecular weight scenarios; dis-entrainment of liquid droplets; stage the operation of multiple flares, by adopting liquid depth to the desired staging pressure.
