COMPLEX PROCESSES

Optimal operation of your SulfurRecovery Unit (SRU) requires measure-ment and control of a complex sequenceof processes. Particularly important iscontrol of the reaction furnace tempera-ture to prevent damage to the refractoryat high temperatures and ammoniumsalt plugging the converters at low temperatures.

Those installations that use the reac-tion furnace to incinerate waste gasessuch as ammonia and hydrocarbonsmust maintain an adequate temperatureto assure their destruction. Advancedprocesses such as O2 enrichment normally involve still higher tempera-tures and demand close monitoring.

TEMPERATURE SYSTEMS

Mikron E2T applies sophisticatedinfrared technology to the solution ofyour furnace temperature measure-ment requirements.

Mikron E2T has designed the PULSARfamily of three detection systems forcontinuous and instantaneous meas-urement of Refractory Temperature(RT), Gas Temperature (GT) andIntegrated Temperature (FF) in thevessel away from the heat, vibrationand corrosive gases. Each systemallows visual inspection of combustionprocesses, refractory cure-out and pre-ventative maintenance while the vesselis pressurized and fully operational.

SUPERIOR PERFORMANCEIndustry wanted the capability to choose refractory, gas or integrated temperature measurementand not simply accept a single temperature of unknown origin. Mikron E2T, utilizing SRU testfacilities, designed three separate models to meet this request.

Industry wanted systems designed for air and higher temperature oxygen-enriched reactors instead ofgeneric thermometers with limited temperature spans of 1000°C. Mikron E2T increases the range of itssulfur reactor models to 900°-3500°F (480°-1925°C).

Industry wanted a simple but rugged monitoring system with cooling capabilities able to withstand continuous exposure to corrosive gases and temperature extremes. Mikron E2Tbuilds monitors with heavy-duty swing-out fixtures and cooling cavities.

Industry wanted an explosion-proof housing as standard without expensive X and Y purge additions.Mikron E2T delivers CSA and CENELEC-certified IR Systems in Explosion-proof Housings

Industry wanted to visually see what the IR thermometer was measuring rather than guessingon what you are focusing. Mikron E2T provides sight-through optics for viewport and furnaceviewing.

Industry wanted to easily clean the window and clear the viewport of debris during operations withoutwaiting for a shutdown to resume thermometer readings. Mikron E2T includes a removable viewport window and a clean-out probe assembly.

Industry wanted to safely field verify the IR thermometers during full operations instead ofdepending upon dedicated thermocouples that burn out. Mikron E2T includes a thermocoupleprobe assembly for verification and cure-out operations.

Mikron E 2T LISTENS WHEN INDUSTRY SPEAKS!

PROVEN EXPERIENCEFor a quarter of a century the energy industry has used Mikron E2T pyrometers in sulfur reaction furnaces,spent acid plants, CO boilers and sulfur burners. Mikron E2T listens when industry speaks, and when clientsasked us whether we could manufacture furnace temperature measurement systems with multiple capabili-ties, we accepted the challenge.

Over 350 refineries, gas plants and petrochemical companies with over 1250 installations world-wide havelooked to E2TECHNOLOGY for accurate infrared (IR) temperature data. When you install Mikron E2T’sRefractory Temperature (RT), Gas Temperature (GT) and Integrated Total Temperature (FF) IR ther-mometers, you are investing in proven experience, superior performance and ultimate cost savings.

SELECT AND INSTALL SYSTEMS T

Selection Criteria

COST SAVINGSIndustry required enhanced capability systems at reasonable prices. Rather than introducing a basic generic instrument andthen adding various required expensive accessories, Mikron E2T introduces complete systems at lower cost with a choiceof refractory, gas, or integrated total temperatures. Well-designed superior performing IR systems do not need to cost more,especially if you listen when industry speaks.

Installation Principles

LOCATION ON FURNACEUtilization of the different temperature measurement systems depends upon the feed gases and burnerdesign of the reactor. If you burn simple acid gas with combustion air, the FF Integrated Total TemperatureSystem should be installed two-thirds of the way downstream from the burner to the waste heat boiler. If thereis a checker wall or choke ring, installation at Locations 2 and 3 are recommended. When you are using yourreactor to destroy ammonia and/or other gases such as BTEX, it is essential that destruction temperaturesbe achieved. To assure incineration, the FF Integrated Total Temperature System or the GT GasTemperature System should be installed at Locations 2 and 3.

With oxygen-enrichment, refractory integrity becomes critically important. Burner design and location becomeparamount in determining the placement of the IR thermometer. The RT Refractory Temperature Systemshould be installed aimed at the area where the designers anticipate the highest refractory temperatures. Forexample, Location 1 is recommended for checker wall protection and Location 4 for tube sheet monitoring.Temperatures at the tube sheet are especially critical since the ferrules and ceramic tube-to-metal junctionsmay face potential excessive temperature excursions as a result of oxygen-enrichment operations.

MOUNTING TO FURNACEThe PULSAR Model M7000SR should be mounted on the horizontal diameter (no greater than +35°) perpen-dicular to the vessel sighting on refractory, or adjacent to the burner sighting on the checker wall or tube sheet.

The SOF-8 Swing-out Fixture mounts to a 3 inch 150 or 300 pound valve connected to the furnace via a spoolwith purge connection. Minimum purge rates for downstream and viewport are 10 SCFM and 1 SCFM respec-tively. The PULSAR’s housing includes a cavity for water or vortex air cooling when ambient temperaturesexceed 125°F (50°C). Flex lines should be used for power input and signal output.
