GENERAL DESCRIPTION

Utility flares are one of the most common and basic flare designs. Utility flares are employed in applications which do not require smokeless burning or in applications where smokeless flaring can be achieved without the use of an additional assist medium. Utility flares therefore, do not require auxiliary gas streams such as steam or air; two fluids normally used to improve smokeless capacity. These flares are typically accompanied by a Dynamic Seal in the base of the tip to reduce purge gas costs and prevent flashback. Additionally, the Flare Industries Utility Tip incorporates a flame retention ring to eliminate flame lift off and provide stable, reliable combustion.

Freestanding Air Assist Flare

Freestanding Air Assist Flare

AIR ASSIST FLARES

ADVANTAGES

h High smokeless rates due to

superior mixing

h Capable of burning heavier hydrocarbons smokeless

h Extended service life

h Lower operating costs at a given smokeless rate

h Lower radiant heat at a given capacity

h Stable, reliable combustion

h Wide range of flow capacities

GENERAL DESCRIPTION

Air assist flares smokeless dispose of heavier waste gases which have greater tendency to smoke. Air Assist flares can be employed at sites where steam may not be available. Air flare systems are composed of two concentric risers and one or more blowers providing supplemental combustion air. A blower forces air into an outer air annulus where the process gas passes through an inner riser and upon reaching the flare tip, these two streams intermix. This air assist has three principle effects: h High-pressure airflow causes turbulence in the waste stream

which improves mixing and therefore enhances combustion efficiency.

h Additional air is induced into the waste gas providing the oxygen necessary for augmented smokeless capacity.

h Constant airflow creates a cooling effect for extended flare tip service life.

ADVANTAGES

h High smokeless capacity due to high velocity air induction and multi-point design h Long service life under normal flow conditions h Lower radiant heat h Effective cost solution for offshore platform use reduces size and expense of flare boom h Able to burn entrained liquids without smoke formation or liquid droplet fallout

GENERAL DESCRIPTION

MACH 1 is the speed of sound. Flare Industries cutting edge

MACH-1 sonic flaring technology operates at this velocity in order to

combust waste gas smokelessly. Sonic flares utilize multi-point exit

nozzles to dispose of high pressure waste gas streams. The MACH-1

Sonic Flare Tip utilizes the pressure of the waste stream (creating sonic

exit velocities) to create turbulent mixing and induce excess

quantities of air for more complete combustion. Sonic flare tips emit

reduced levels of radiation and can be placed at lower, less visible

elevations. This advanced flaring technology is excellent for

applications with high pressure waste gases and high capacity

smokeless requirements.

variable sonic nozzles allow the exit area to vary with pressure, ensuring constant sonic velocity of

waste gas. This industry proven technology guarantees sufficient inspiration of air to ensure 100%

smokeless combustion and infinite turndown. Radiation levels are also minimized throughout the entire

range of flow, yielding shorter stack heights and boom lengths and reducing material costs.

Additionally, the VariMach has the lowest purge rate of any flare technology on the market, minimizing

utility costs while maintaining flashback protection.

airmach Sonic Flares

A IRMACH SON IC FLARE

ADVANTAGES

h Same advantages as Mach-1 sonic flare, .e., - High smokeless capacity sonic flow - Long service life - Low radiation - Flares entrained liquids h Smokeless flaring at sub-sonic flows

h Minimal flame impingement due to air flow

h Blower air creates a cooling

effect to increase the tip lifespan h Lower noise than standard

GENERAL DESCRIPTION

The AirMach flaring system was developed to specifically address the

problems associated with sonic velocity flares operating at sub-sonic

flow rates. Sonic flares operating at sub-sonic exit velocities will

smoke when heavier waste gas flows are present. The AirMach

provides smokeless flaring performance at lower flow conditions

utilizing a blower for combustion air. In this application, the AirMach

operates as a traditional air-assist flare. As the waste gas flow

increases, the flame geometry transitions from an air assisted

smokeless condition to a momentum dominated smokeless

performance. Unlike conventional air-assist flares, the AirMachs

blower air requirement reduces as the waste flow increases. Typically,

the AirMach blowers horsepower requirement is over 50% less than a

ADVANTAGES

h Capable of burning low

BTU gas streams h Disposes of waste gas with

high CO2 and CO content

h Higher flow capacity for high CO2 and CO waste streams

h Stable, reliable combustion due to flame retention ring

h Long service life under normal flow conditions

GENERAL DESCRIPTION

Carbon Dioxide, or CO2, is often used in fire extinguishers and snuffing systems; so you can imagine what it is like to try and burn it. Many of our clients have flare applications which require disposal of gas streams with high carbon dioxide content. As the volumetric percentage of CO2 increases, the flaring capacity of a given flare system decreases. The Flame Ring Flare Technology is used to provide a veritable ring of fire at the perimeter of the flare tip; thus ensuring proper ignition and stable combustion of these waste gases. This technology also increases the capacity of the flare system by preventing auto-suppression of the flame, caused by high quantities of CO2, CO, or low heating value waste streams. The Flame Ring Flare Tip by Flare Industries is the perfect solution for these types of applications.

GENERAL DESCRIPTION

The Peacock Oil Burner was developed to flare liquid hydrocarbons without liquid fallout or soot formation (smoke). These burners provide excellent service for well testing operations and have been used in applications all over the world, including the Gulf of Mexico and Persian Gulf. 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. This particular burner nozzle 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.

THE CONTINUUM IGNITION SYSTEM

the CONTINUUM Ignitor

ADVANTAGES

h Fully retractable for ease of

maintenance h Low maintenance costs:

does not require crane

h Low maintenance costs: no plant shutdown for maintenance

h Eliminates need for ladders and

platforms

h Constant re-ignition every 20 seconds, 24 hours a day

h Eliminates need for pilot gas in most applications

GENERAL DESCRIPTION

The CONTINUUM Ignitor is a durable track mounted device that is capable of sliding up and down the side of the flare. This allows the user to easily retract the ignitor to grade using a pulley and winch system, thus providing a product which is fully and easily serviceable at a very low cost. The CONTINUUM Ignition System can be mounted on vertical as well as horizontal flare systems, and for both onshore and offshore applications. The built in pulley and winch retractibility package will avoid the exorbitant costs involved with renting a crane to service pilots or ignition equipment located hundreds of feet above grade. The unit utilizes a high voltage electric arc to ignite a combustible air/gas mixture. This arc occurs every 20 seconds for a two second duration (timing is adjustable). The CONTINUUM Ignition System provides a steady, stable ignition source due to the fact that it sparks every few seconds, 24 hours a day, providing constant re-ignition. The CONTINUUM actually arcs inside a slip stream chamber. The slip stream assembly is an alloy tube that diverts some waste gas into a separate chamber, thereby creating a combustible air/gas mixture. This feature is what allows the CONTINUUM to function without pilot.

ADVANTAGES h Low fuel consumption

h Ease of installation and/or retro-fit applications h Durability due to high alloy, stainless steel construction h Reliability: ignition and re-ignition h Flame stability: wind velocities up to 150 mph (240 km/hr)

GENERAL DESCRIPTION

The Model 245 Fuel Efficient Flare Pilot is a high alloy, stainless steel pilot operating on fuel gas and in conjunction with a flame front generator. It is composed of the pilot head, fuel gas line, ignition line, inspirator, and optional thermocouple. The pilot head assembly includes a flame retention nozzle and wind shroud which are both manufactured from 310 stainless steel for extended service life. This specially engineered pilot head is capable of sustaining a stable flame in winds of up to 150 mph. Pilot fuel gas travels up the flare in a one inch line and as it passes through the inspirator at the base of the pilot, air is induced into the line. This combustible air/gas mixture exits the pilot gas line at the pilot head nozzle and is ignited by a fireball which travels up the ignition line from its inception at the flame front generator. The Model 245 Flare Pilot is designed for fuel efficiency, durability, reliability, and ease of installation.

h Ease of installation and/or

h Flame stability: wind velocities up to 150 mph (240 km/hr)

GENERAL DESCRIPTION

The Model 250 ENGERGEX Pilot is a high alloy, stainless steel pilot which combines a high voltage electronic Excitor and a high energy spark rod to provide rapid, reliable ignition. More importantly, the ENERGEX pilot provides instantaneous re-ignition if the pilot should ever lose its flame. This pilot system uses a fuel gas line much like other standard pilots, however, instead of a flame front generator it utilizes the Excitor which produces a high voltage arc inside the pilot nozzle. An inspirator induces air into the fuel gas line creating a combustible mixture for the Excitor to ignite. After ignition, if the flame should ever go out the thermocouple will sense this loss of flame and will send a signal to the control panel. The Excitor then begins to arc until the pilot is lit and the thermocouple no longer senses a flame failure. The spark rod, because of its integral location in the pilot head, can initiate re-ignition immediately. The Model 250 ENGERGEX Pilot is an innovative solution for flaring applications in which extended downtime is a critical concern.

GENERAL DESCRIPTION

Once again, Flare Industries has launched an innovation into the combustion and pollution control marketplace. The Model 270 RETRAX is a high-tech, retractable, electronic pilot which meets the technical requirements of our clients. This advanced design allows the plant operators to lower the RETRAX pilots individually or all at once for ease of maintenance. Since the RETRAX can be lowered from grade, operators need not wait for a plant shut down to service the pilots. The Model 270 RETRAX allows customers to forego ladders and platforms all together which further saves our clients money in capital expenditure. The Model 270 RETRAX Pilot, like the Model 250 ENGERGEX, is a high alloy, stainless steel pilot which combines a high voltage electronic Excitor and high energy spark rod to provide rapid, reliable ignition.More importantly, the RETRAX pilot provides instantaneous re-ignition if the pilot should ever lose its flame. This pilot system uses a fuel gas line much like other standard pilots, however instead of a Flame Front Generator, it utilizes the Excitor which produces a high voltage arc inside the pilot nozzle.

Model 320 Flame Front Generator

GENERAL DESCRIPTION Flame front generator technology is an effective, time proven ignition system which has been widely used in flaring applications for decades. The inherent reliability, rugged construction, and ease of operation as well as its economic advantages have allowed the flame front generator (FFG) to remain one of the most popular forms of pilot ignition in the industry. The FFG is easily adaptable to any pilot system which incorporates an ignition tube and may be installed up to 1 mile (1600m) from the base of the flare stack. Flare Industries designs and manufactures several styles of FFG systems which can operate in automatic or manual mode. Flame Front Generators first meter and then combine fuel gas and air, thereby creating a combustible air/gas mixture in the ignition line. This metering and mixing process is accomplished through the use of small valve trains placed on the FFG control panel. Model 300 Flame Front Generator

The Model 300 Manual Flame Front Generator is a manual system which requires an operator to physically initiate the ignition process by depressing a button on the FFG control panel. Once the ignition line is filled with this com-bustible mixture, a spark is created within the ignition chamber and igniting the mixture. Next, a flame front or fireball propagates through the ignition tube and ignites the pilot(s). Once the pilots are lit, the flare is ready to ignite the process gas exiting the flare tip. Model 320 Automatic Flame Front Generator

The Model 320 initiates ignition and re-ignition automatically while continually monitoring the ignition system via a UVI 550 pilot monitor or thermocouple. Model 310/330 Self Inspirating Flame Front Generator

The Model 310 is Flare Industries manual self inspirating flame front generator while the Model 330 boasts an automatic control system for ignition and re-ignition. These two models do not require instrument air as they are designed to inspirate ambient air. Flare Industries employs this technology when a client does not wish to supply instrument air or when located in a remote area where instrument air may not be available. This extremely reliable and easy to operate ignition system uses the same basic design principles and possesses most of the same features as the Models 300 and 320.

GENERAL DESCRIPTION

Exorbitant fuel costs is perhaps the most distressing concern when considering which type of thermal oxidizer to choose. One way to hedge this variable cost is to employ some form of heat or energy recovery. FIRECATTM Recuperative Oxidizers employ shell and tube heat exchangers, boilers, or hot oil heaters to take advantage of the heat available in the flue gases. In this way, flue gases constantly heat oil, create steam, or preheat waste gases and combustion air, thereby reducing fuel gas consumption.

GENERAL DESCRIPTION

Does a typical thermal oxidizer really burn more fuel per day than the space shuttle Discovery? Well, thats debatable. The fuel savings of the Flare Industries Regenerative Thermal Oxidizer (RTO) versus a standard thermal oxidizer is not debatable. This technology is most often used to dispose of high volume, hydrocarbon laden air streams which typically require large quantities of fuel gas to maintain the combustion chamber temperature. The Flare Industries RTO achieves at least 95% effective heat recovery which saves our customers money in fuel and daily operating costs. Converting solvent laden fumes into harmless byproducts is the primary objective of the Flare Industries RTO. This state of the art design consists of a central combustion or residence chamber and two or more media filled recovery beds. The RTO directs process gases to the inlet and outlet chambers alternately, thereby reheating the media beds. These media beds then preheat the waste stream, providing at least 95% effective heat recovery, while still maintaining greater than 99% destruction efficiency.

Enclosed Landfill Flares

FULLY ENCLOSED FLARE

GENERAL DESCRIPTION The Fully Enclosed Flare (FEF) is a completely enclosed flare system in which combustion occurs inside an insulated flare stack and in a controlled environment. Enclosed combustion ensures that all radiation, light, flame, and noise are imperceptible in sensitive areas. The FEF consists of the following components: flare burner, enclosed stack, combustion air system, control panel, and other optional items. Burner and Pilot The FEF Burner is the most advanced burner available in the industry today. Its design allows for high destruction efficiency and low emissions. The NOX and CO emission rates meet or exceed the requirements of most regulatory agencies (i.e., SCAQMD). This design allows for efficient combustion in either forced draft or natural draft configurations. Our compact, fuel efficient electronic pilot provides trouble-free, reliable ignition. Enclosed Stack The enclosed stack is built in modules to allow for ease of shipment and installation. It is insulated with 2 to 3 of high temperature refractory. The stack size is based on flow rate to ensure a minimum of 0.6 seconds residence time for reduced emissions. Combustion Air System The FEF can be designed to operate as either a natural draft or forced draft system. The natural draft system has the lowest operating costs and simplest design. In the natural draft system the air is controlled using a set of opposed blade air louvers that open or close as required to maintain a constant combustion chamber temperature. The forced draft system utilizes a blower assembly to provide the necessary air. This system is ideal where high winds may cause a reverse flow in a natural draft system, thereby extinguishing the flame. Control Panel The FEF control panel can be supplied in either a NEMA 4X or NEMA 7 enclosure. Temperature controls, safety systems, remote start / stop, and alarm contacts are standard items. A completely automated system is the design basis for our controls system.

GENERAL DESCRIPTION The SEF Bio-Gas flare is an elevated flare (also referred to as the Candlestick flare) complete with a shroud to reduce flame visibility and improve thermal destruction efficiency. Flare Burner The SEF Burner is constructed from high temperature alloy steel to prevent corrosion or thermal degradation. A proprietary flame retention ring is used to provide the stable combustion required for efficient vapor destruction and a dynamic purge seal is included to reduce the chance of flashback caused by air entry into the flare. Flame Shroud The flame shroud used on the SEF has several purposes. The shroud is designed to prevent down drafts from extinguishing the flame. In addition, the shroud reduces the amount of visible flame seen on the flare and provides a chamber for more complete combustion. The amount of heat radiation produced by the flare is reduced allowing the stack height to decrease. Flare Riser The SEF is supplied with a self-supported flare riser, complete with base section, designed to be mounted on a concrete

UVI 550 Pilot Monitor

UVI 550 PILOT MONITOR

ADVANTAGES h Instantaneous response time h Ease of maintenance

located at grade

h Durability not located in flame impingement zone

h Ultraviolet detection (not

affected by the sun) h Penetrates fog, rain, sleet,

smog, or smoke

GENERAL DESCRIPTION

The UVI 550 pilot monitor was designed and developed in order to satisfy several objectives: remote flame detection, reliability, durability, ease of maintenance, and rapid response time. The result is an extremely reliable, durable and inexpensive pilot monitoring device. The UVI 550 is used to detect the presence of a pilot flame at distances of up to 550 feet. If the UVI 550 detects the absence of flame or flame failure for an adjustable amount of time, a set of dry form C contacts are activated and the pilot re-ignition system is set into motion. The response time is much quicker than when using a standard thermocouple because the UVI 550 reacts instantaneously. A standard thermocouple goes into alarm only after it has cooled down below the set temperature of the thermocouple controller, whereas the UVI can immediately sense the loss of flame. The UVI 550 measures a specific narrow band of ultraviolet radiation that is common only to burning hydrocarbons. The sensitivity of the UVI 550 is such that it can detect radiation from an 8 inch flame at a distance of 500 feet. The ultraviolet wave length can be sensed through a veritable barrage of fog, rain, sleet, smog, or even smoke. The UVI 550 can be located at any position (full 360 degrees) relative to the flare stack since solar ultraviolet rays have no effect on the monitor. Most infrared detectors can not be positioned so that they face east or west due to false readings and interference from the sun. The UVI 550 is technologically superior to infrared pilot monitors as well as being less expensive. Another obvious advantage is ease of maintenance given that the UVI is located at grade.

Knockout Drum Skid

KNOCKOUT DRUM

ADVANTAGES

h Disentrains liquid droplets h Prevents flaming rain

h Reduces flare smoke h Recovers liquids

GENERAL DESCRIPTION

Whenever a process requires that entrained droplets be removed

From a vapor stream, Flare Industries includes a knockout drum in the

system design. Condensation can occur when hot process gases

cool considerably in the flare gas header and riser, and some gases

also go to dew point at ambient temperatures and pressures and

can therefore generate liquids. These droplets must be removed in

order to avoid the phenomenon known as flaming rain, which occurs

when liquid droplets are blown out the top of a flare stack along with

ignited process gases. In order to avoid this hazard, Flare Industries

provides the knockout drum. Designed to remove particles as small

as 50 microns in size. The vessel can be outfitted with a wide variety

of instrumentation. Flare Industries provides both horizontal and

vertical configurations.

ADVANTAGES

h Prevents flashback

h Prevents surging of gases

h Creates positive pressure in the flare header

h Disentrains liquid droplets

General Description Purge systems are the perfect solution for preventing air infiltration in the flare stack and header system, however it is possible to lose purge gas supply. When purge gas is lost or interrupted, the flare system and plant can once again face the possibility of flashback and/or catastrophic explosion. The liquid seal drum is a specially designed vessel containing a predetermined level of water in the base of the drum. As the waste/process gas enters the drum through the flare system header, it is diverted down into the water and forced to bubble through the liquid seal. The gas then travels up through the flare stack and tip for combustion. The main purpose of the liquid seal drum is to stop flame propagation. By quenching the flame with a barrier of water, Flare Industries Liquid Seal design achieves this purpose as well as providing other intrinsic design advantages. Second, the liquid seal acts as a large check valve so that gas can not travel upstream for any reason. A third function of the liquid seal is to disentrain liquid droplets. Thus, the liquid seal drum provides flame arresting capabilities, acts as a check valve, and knocks liquids out of the waste gas. Liquid seals can be designed as a separate vessel or as an integral part of the flare riser structure.

Dynamic Seal

DYNAMIC SEAL

ADVANTAGES


h Less purge gas required (94% less)

h Significant cost savings over time

h Extends flare tip working life by preventing burnback

h Lower capital costs

h Not affected by wind velocities, thermal contractions, or flow oscillations

h No moving parts (will not bind, wear out, or fail)

h Functions with wide range of gases (heavy and light)

h Extremely low pressure drop

General Description Flashback prevention + low purge gas consumption + low cost = Flare Industries Dynamic Seal. It is a very simple equation. Flashback occurs when ambient air penetrates the flare stack and mixes with waste gas, creating a combustible mixture. The most common and most acceptable safety measure is to purge the system with a gas that does not contain oxygen and will not reach dew point at ambient conditions. Purge gas constantly flows through the flare header piping and flare stack insuring that air infiltration does not occur. Sweeping a stack with purge gas twenty four hours per day without a purge seal can result in exorbitant operating expenses over time. The Dynamic Seal is a simple innovation insuring reliable operation and significant cost savings year after year. The reverse conical baffle design reduces flow area in the flare tip while simultaneously increasing purge gas velocity. A vortex effect is created in the exiting purge gas which inspirates intruding air. This intruding air is drawn out of the boundary layer and into the exiting purge gas flow column, thus purging the flare tip. The Dynamic Seal can be used in horizontal as well as vertical applications due to the fact that it relies on fluid flow rather than gravity in order to operate properly. Since there are no moving parts, the Dynamic Seal virtually lasts forever. This Flare Industries technology offers several inherent cost and safety advantages. Also referred to as a velocity seal.

h Significant cost savings over time

h Maintains gas seal for up to 8 hours if purge gas is lost

h No moving parts (will not bind, wear out, or fail)

h Functions with wide range of gases (heavy and light)

General Description Flashback. This phenomenon occurs when ambient air penetrates the flare stack and mixes with waste gas, creating a combustible mixture. An ignition source can then create an explosion inside the flare stack which could flashback through the flare header. This flashback, or flame propagation, can travel through the flare header piping and propagate back to the source, thus causing an industrial disaster. The Flare Industries Molecular Seal is used in conjunction with purge gas in order to avoid this unpleasant occurrence.

The most common and most acceptable safety measure is to continuously purge the flare system with a gas that does not contain oxygen and will not reach dew point at ambient conditions (fuel gas and nitrogen are the most commonly used fluids). Purge gas constantly flows through the flare header piping and flare stack insuring that air infiltration does not take place. Sweeping a stack with purge gas twenty four hours per day without employing a purge gas seal can result in exorbitant operating expenses over time; especially for large diameter stacks.

The Molecular Seal is a purge reduction device which allows the flare system operator to use 98% less purge gas while continually sweeping the system. The savings in daily purge gas consumption over the long run makes for a short payback period on the initial capital investment of the molecular seal. Also referred to as labyrinth or density seal.
