Air assisted flares enable the smokeless combustion of low pressure waste gases. Air (or Gas) assisted flares can be used when no steam is available on site. Air assisted flares use forced draft Air or Gas to create turbulence ensuring that sufficient primary combustion air is supplied to the flame. The amount of air and hence the size of the tip and riser depend on the degree of smokeless operation required and the maximum flow for smokeless operation. Key features Proprietary design to maximize the mixing of waste gas and air streams and to create turbulence in the combustion zone. Variable speed fans, to supply the optimal amount of Air (Gas) Use of wind deflectors if required, to prevent flame impingement Flame holders around the periphery of the flare tip to ensure stable operation. Use of high grade alloys to enhance lifetime of the flare tip. The use of combustion/mixing air to cool the flare tip and thus enhance its lifetime Key advantages Smokeless operation under a wide range of operating conditions Smokeless flaring of high molecular weight gases Air cooling of the flare tip, resulting in longer lifetime and lower operation and maintenance costs Reduced radiant heat for a given capacity Applications Upstream oil & gas sector Chemical and petrochemical industries including refineries Tank farms and terminals Pipeline transport LNG and NG terminals and compressor stations

A SRU incinerator is an oxidation-reduction reactor for the recovery of elemental Sulphur from H2S rich waste gases. The first stage of the so called Claus process, is the complete free flame oxidisation of typically 1/3 of the H2S to SO2 in a reaction furnace (H2S + 1½ O SO2 + H2O). The SO2 and the then remaining H2S undergo the Claus reaction both in the reaction furnace and in a series of catalytic reactors (2 H2S + SO2 3S + 2 H2O) resulting in the overall chemical reaction H2S + ½ O H2 + S. Key Features One combustion chamber with mixing wall Part of the waste containing H2S is injected through the burner, the remainder before the mixing wall. The burner is a robust Multifuel design suitable for the combined combustion of different waste gas and gaseous or liquid support fuel streams. The mixing wall ensure the waste and combustion gases combine and also ensures a uniform temperature profile to improve the overall efficiency of the reaction. Key Advantages - Sulphur recovery – Ultra-low NOx combustion possible – Complete oxidisation of all hydrocarbons – No CO formation – Complete odour destruction – Destruction efficiency over 99.99% – For waste air/gas streams containing a high percentage of H2S

The Tulip Vortex burner was developed specifically for (temperature controlled) combustors for the treatment of lean waste gases and vapours. It employs the same design philosophy as the Ultra-low NOx Tulip Vortex burners but is designed for the combustion of lean waste gases, whilst minimizing support fuel requirements. The burner creates an intense gas recirculation zone near the burner to ensure that waste gas, flue gas and combustion air are mixed. The resulting moderate flame temperature minimizes NOx formation. The homogeneous temperature profile and swirl result in complete oxidation and low CO emissions.

Europem ignition systems and pilot burners have been developed for their continuous reliable operation in harsh environments and in all weather conditions. High grade alloys are used and critical parts are mounted in protective housings to ensure the long lifetime of the equipment. Both High Energy electronic spark ignition and flame front ignition systems are offered. Flame Front Ignition (FFG) systems have been used as the workhorse of the flare industry for many years. The FFG pilot ignition line is filled with a combustible gas/air mixture, then ignited by a spark on the ignition skid to generate a flame front travelling through the ignition line up to the flare burner. This flame front subsequently ignites the pilot gas and the waste gas in the flare burner. Both manual and automatic flame front ignition systems can be offered. High Energy Electronic spark ignition uses a high voltage electric arc to ignite the combustible pilot air-gas mixture. The arc is generated at fixed intervals for a limited period of time. EP-ESPI Electronic Spark Ignition EP-FFGI Flame Front Ignition EP-CIS Combined Electronic and FFG Ignition systems can be supplied with either Manual or Automatic ignition controls, or a combination of both. For safe areas and for explosion proof areas, either onshore or offshore and with retractable or non-retractable ignitor rods. Pilot Burners Pilot burners can combine one or more of the ignition systems described above and with a continuous flame to ensure that combustible waste gas mixtures are always ignited and combusted. Europem pilot burners have the following features: High Energy Ignition to ensure reliable ignition regardless of moisture levels, dirt or atmospheric conditions Ignition rod, spark plug and thermocouple are housed in the main pilot body for added protection and prevent exposure to high temperatures Made from high grade stainless steel alloys Pilot burners can be supplied with Single or Duplex Thermocouples or Thermocouples plus Ionisation detection. Self-aspirating venturi mixers or with forced draft air High temperature cable with pre-wired plug and socket connections AC or DC electronics

Europem can supply complete flare systems as well as Flare Tips on their own for replacement or upgrade and refurbishment projects. The following standard Flare Tips are available: EP-PF Pipe Flare EP-EAS External Assist Steam EP-IAS Internal Assists Steam EP-EAS/IAS External/Internal Assist Steam EP-AA Air Assist EP-GA Gas Assist EP-CAA Compressed Air Assist EP-HP-PF High Pressure Pipe Flare EP-HP-MAS High Pressure Multi Arm Sonic EP-MP Multi Point EP-BP Burn Pit Special tailor made Flare Tips can be offered for specific applications. Europem Venturi Flame Shield (VFS) Europem has developed the proprietary Venturi Flame Shield giving double protection against flame lick. The VFS also pushes air up towards tip exit, leading to an enhanced and more stable combustion process. The VFS can be integrated into most Europem Flare Tips but is particularly suitable for H2S flares, ammonia flares, hydrocarbon flares and lean waste gas flares.

Utility Flares (Pipe Flares) are the most basic flare design available, to provide a robust, reliable and flexible solution for the flaring of large volumes of low pressure waste gas when smokeless operation is either not required or can be achieved without an assisting medium (like steam, air or gas). Reliable operation at both full load and partial load is possible. Key features Flame holders fitted on the periphery of the flare tip ensure stable operation. These flame holders provide a zone of recirculated flue gases, which prevent flame lift off, from the flare tip. Wind deflectors to prevent flame impingement, which prevent a low pressure zone, downwind of the tip. Pilot burner arrangement to further stabilise the flame. Use of high grade alloys to enhance lifetime of the flare tip Use of dynamic seal to reduce purge gas requirements and prevent flash back. Key advantages Low investment and operational costs Low maintenance costs with the use of high grade alloys and the robust design. Reliable and stable flaring in a wide range of operating conditions Large turn-down ratio Applications Upstream oil & gas sector LNG terminals and NG compression stations Chemical and petrochemical industries including refineries Food processing industries Municipal solid waste treatment (biogas and landfill gas) plants Temperature controlled combustors and thermal oxidisers.
