Flares - Import export

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

Mobile Flare Systems Many situations call for the use of temporary flare systems e.g. cleaning and inspection of storage tanks and pipeline networks. Also chemical and petrochemical plant revamp projects. For these situations Europem has developed a range of mobile flare systems using either pipe flares or assisted flares. Mobile flare units can be free standing, transported by truck or they are ready mounted on a trailer. Our mobile systems can be supplied on a procurement, lease or rental basis.

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

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.

Europem can supply complete flare systems which include knock-out vessels, water seals, molecular seals, conical purge gas seals, pilots and ignition systems. Additionally, Europem has developed a unique ATEX zone O vapour extraction system for use in conjunction with VRU’s, combustors, flares and thermal oxidisers. Vessels Europem supplies the upstream equipment to remove droplets from gases or provide a seal between the flare burner and the waste gas piping in order to prevent air from infiltrating the flare riser and thus prevent flash back. Purge gas is employed to prevent flash back by stopping air ingress to the flare gas header. Molecular seals and also Conical seals are both devices that reduce purge gas flow rates. Conical seals will require a slightly higher purge gas flow rate than a Molecular seal, but have the advantage of a simpler more economic design. This design cannot be blocked by debris, sludge or ice formation and does not put additional load on the flare structure, being integral to the flare riser. Although purge systems are the perfect solution for flash back prevention, the flow of purge gas can always be lost. A water seal can be installed to provide the ultimate barrier to flame propagation upstream in the waste gas piping. Vessels can be supplied either as an integral part of a flare system or as stand alone items. Both vertical, typically integrated with the Flare riser, or horizontal configurations are available. Features Water Seal Vessels equipped with an overflow weir to maintain a minimum water level, anti-pulsation baffles and a dip-pipe with distribution cone forcing the waste gas to flow through the water bath. Molecular Seals are equipped with a riser pipe and cap to either form a layer of purge gas on the top, when the purge gas is lighter than the air, or on the bottom when the purge gas is heavier than the air of the vessel Conical Seals are in fact an inverted conical restriction made as a section of the riser. This restriction will locally induce a higher waste gas velocity which in turn entrains any penetrating air and carries it up to the flare burner. Knock Out Drums contain packing to separate droplets from the waste gas. A liquid level control with automatic purging prevents the vessel from overfilling.

Enclosed ground flares are suitable for thermal destruction of a wide range of waste gases including rich and lean gas mixtures. Where the burners are housed in a cylindrical vessel resulting in the combustion process being out of sight and more controllable in comparison to elevated flares. Enclosed ground flares can also be designed with or without temperature control. With temperature control, a minimum residence time, at a specific combustion temperature can be set and guaranteed. Consequently, temperature controlled ground flares, also called combustors or thermal oxidisers, can meet the most stringent emission values. The emissions can be monitored with chemical emission monitoring (CEM) units. Features Can be equipped with Europem’ proprietary Tulip Venturi Burner for the combustion of lean waste gases or with multiple burners designed for the flaring of large capacities (modulated flaring is possible) Operating at varying temperatures depending on the load of the ground flare Smokeless operation and high destruction efficiency by ensuring some turbulence around the flame and sufficient residence time at elevated temperatures Simple control system, because the combustion temperature is allowed to fluctuate Provisions for support fuel in cases of combustion of lean waste gases or cooling air in cases of rich waste gas combustion Can be supplied as natural draft or forced draft system Can be supplied with or without temperature control Advantages No visible flame and reduced visibility of the installation due to lower stack heights Reduced noise levels Minimal heat radiation Possibility for emissions sampling High destruction efficiencies and smokeless operation Applications Tank farms and ship loading terminals Chemical and petrochemical industries Food processing industry Waste management plants
