2 2E TE TECHNOLOGY CORPORATIONINFRARED FLARE STACK DETECTION SYSTEMSPILOT FLAME, FLARED GAS AND SMOKE MONITORSPILOTS AND FLARESContinuous monitoring of <strong>pilot</strong> <strong>flame</strong>s<strong>and</strong> <strong>flare</strong>d <strong>gas</strong>es is critical to ensurethat the <strong>gas</strong>es will be ignited <strong>and</strong> toconfirm compliance with government-setflaring time limits. Thermocouplefailure, <strong>flame</strong> movement,varying luminosity <strong>and</strong> adverse climaticconditions are just a few of theobstacles which have to be overcometo gain long-term reliabilitywithout false alarms.SMOKEContinuous monitoring of the <strong>flare</strong><strong>stack</strong> for excessive smoke is criticalto ensure complete combustion. Tomeet safety <strong>and</strong> environmental requirements,upset conditionsrequire immediate adjustments ofsteam. Real-time automatic injectioncontrol replaces excessive steamconsumption with significant costsavings.SAFETY ANDENVIRONMENTALPROTECTION✰ATMOSPHERICSIGNAL CORRECTION✰SUPERBSIGHT-THROUGHOPTICS✰SINGLE MODULEINSTRUMENT✰CSA AND CENELECCERTIFICATIONSTACK MONITORSE 2 TECHNOLOGY CORPORATIONapplies sophisticated <strong>infrared</strong>technology <strong>and</strong> advanced modularhousing design to the solution of your<strong>flare</strong> <strong>stack</strong> monitoring requirements.E 2 TECHNOLOGY has designed theQUASAR family of three <strong>detection</strong><strong>systems</strong> for continuous dutymonitoring of <strong>pilot</strong> <strong>flame</strong> (PM), <strong>flare</strong>d<strong>gas</strong>es (FM) <strong>and</strong> smoke particulate(SM) from <strong>flare</strong> <strong>stack</strong>s. The sightthroughoptical system <strong>and</strong> choicesof fields of view allow the QUASARto be positioned as far as1mile4(400 m) from the <strong>flare</strong> <strong>stack</strong>. Each ofthe three <strong>systems</strong> is complete with aremovable camera module, dualoutputs, explosion-proof housing,internal heater <strong>and</strong> cooling cavity<strong>and</strong> precision alignment vernierswivel mount.WE MAKE INFRARED WORK FOR YOU


SELECT AND INSTALL MONITORS TSelection CriteriaOver 350 refineries, <strong>gas</strong> plants <strong>and</strong> petrochemical companies with over 1100 installations worldwidehave looked to E 2 TECHNOLOGY for accurate <strong>infrared</strong> (IR) temperature data. When youinstall E 2 T QUASAR Flare Stack Monitors for <strong>infrared</strong> solutions you are investing in provenexperience, superior performance <strong>and</strong> cost savings.PROVEN EXPERIENCEFor a quarter of a century the energy industry has used E 2 T pyrometers in sulphur reactionfurnaces, spent acid plants, CO boilers, sulphur burners <strong>and</strong> on tubes in high temperaturereformers. E 2 T listens when industry speaks <strong>and</strong> when clients asked us whether we could manufacturebetter Pilot Flame, Flared Gas <strong>and</strong> Smoke Monitors we accepted the challenge.SUPERIOR PERFORMANCEIndustry wanted a simple but rugged one-piece monitor.No more two-piece optical camera <strong>and</strong> separate amplification circuitry.E 2 T builds a single complete electro-optical IR module.Industry wanted a manufacturer who would build IR pyrometer <strong>and</strong> amplification circuitry.No more adapting a generic IR thermometer from another source.E 2 T designs <strong>and</strong> builds the entire system.Industry wanted an Explosion-proof Housing as st<strong>and</strong>ard.No more additions of X or Z purges.E 2 T delivers their IR module in a CSA <strong>and</strong> CENELEC Explosion-proof Housing.Industry wanted better optics.No more 1000 feet (300 m) limit.E 2 T lengthens the range to 1300 feet (400 m) or more depending upon the <strong>flame</strong> size.Industry wanted to detect invisible hydrogen <strong>flame</strong>.Not just orange hydrocarbons.E 2 T includes the only IR filtered detector sensitive to hydrogen.Industry wanted Pilot, Flared Gas <strong>and</strong> Smoke Monitors for all weather conditions.Not just sunny days.E 2 T provides an automatic gain control for adverse weather conditions.Industry wanted to buy monitors directly from the manufacturer.Not just through an OEM intermediary.E 2 T sells direct.E 2 T LISTENS WHEN INDUSTRY SPEAKS!COST SAVINGSIndustry required new well-designed monitors at reasonable prices. Rather than increasing pricesabove those currently set for older existing monitors, E 2 T lowered prices. Simplicity, a new design,manufacturing the complete system <strong>and</strong> selling direct all contribute to lower cost. Welldesignedsuperior performing instruments do not need to cost more, especially if you listenwhen industry speaks.


HAT MEET YOUR REQUIREMENTSInstallation PrinciplesDISTANCE TO STACKWhen installed at ground level, the QUASAR Pilot, Flare <strong>and</strong> Smoke Monitors should belocated at a distance from the base of the <strong>flare</strong> <strong>stack</strong> equal to 1.0-3.0 times the <strong>stack</strong> height.These monitors could also be mounted on a building or a vibration-free vessel. This would allowa location closer to the <strong>stack</strong> yet maintaining the acceptable angle.FIELD OF VIEWTo monitor the maximum number of <strong>pilot</strong>s with one instrument <strong>and</strong> tomonitor <strong>flare</strong>d <strong>gas</strong>, the field of view should include the entire top ofthe <strong>flare</strong> <strong>stack</strong>. The st<strong>and</strong>ard field of view from monitor to top of <strong>flare</strong><strong>stack</strong> is 75:1. To monitor smoke particulate, the field of view is evenlarger, 60:1. For applications requiring closer installations (such asoff-shore <strong>flare</strong>s), 37.5:1 is available. For distances exceeding 1,000feet (300 m), 150:1 is required.GEOGRAPHICAL LOCATIONFor installation in the northern hemisphere it is recommended thateach monitor be located true south of the <strong>flare</strong> <strong>stack</strong> within + 45 o . Inthe southern hemisphere the monitor should be located true north ofthe <strong>stack</strong> within + 45 o . If an instrument must be installed in the oppositedirection ensure the monitor does not receive direct solar radiationduring any time of the year.DIRECTION OF WINDDo not install a monitor at a location where the prevailing winds blowdirectly away from the instrument toward the <strong>stack</strong>. This will make itquite difficult to view the <strong>flame</strong> <strong>and</strong> smoke. For example, in the sketchwhen the wind is blowing true north, location “B” is not recommended.Locations “A” <strong>and</strong> “C” are preferred for they allow the <strong>flame</strong>s <strong>and</strong> smoketo be seen when blown directly north of the <strong>flare</strong> <strong>stack</strong>.
