THE NEEDThe control of many petrochemical and chemical processesrequires monitoring of multiple chemical species within yourprocess’s feed, reaction, or effluent gases. Unfortunately, multipletechnologies are often required to monitor all of the requiredspecies. AMETEK Process Instruments has responded toindustry’s need for a rugged, multi-component, multi-technologygas analyzer in an explosion-proof package.

The Western Research® Model 932 is designed for a varietyof gas monitoring and process control applications. Whether it’sreliable H

2S and NH

3 analysis for feed-forward control of modern

SRU plants, monitoring of H2S and COS for the control of amine-

based SRU tail gas treating plants, or any one of hundreds ofother applications, the 932 analyzer is the best choice for reliable,field-proven, and rugged on-line analysis.

For those applications where sample condensation mayoccur, the Model 932 analyzer system is available with a heatedcell option. The fully integrated AMETEK Process Instrumentsheated cell ensures reliable dew point control without running therisk of plugging, contaminating, or flooding the analyzer.

A flexible sampling system, which includes an optionalintegrated electrically heated acid gas sampling probe (HAG) forsafe, reliable acid gas sampling, as well as optional on-boardsample switching hardware and software, makes the Model 932one of the most flexible, explosion-proof, multi-componentanalyzers available on the market.

Many process applications also require the detection of non-UV absorbing species, such as H

2 (for H

2S/COS/H

2 measurement

in amine-based tail gas treating contactor overhead applications).The sensor required for the measurement of H

2 can be incorporated

into the Model 932 thereby eliminating the need for additionalprocess analyzers in some applications.

No matter what your needs are, this flexible, low-maintenanceanalyzer design will be the answer to many of your complexprocess control requirements.

THE MEASUREMENTThe Western Research® Model 932 uses AMETEK’s proprietaryhigh-resolution UV technology in a dual-beam, dual-wavelengthconfiguration with pulsed UV lamps to ensure optimal performance withlow noise and minimal baseline and span drift.

Analysis linearity and measurement stability is maximized byusing high-intensity, low-energy hollow cathode UV source lampsthat provide a resolution that is better than 0.02nm. This highresolution design enables unparalleled linearity over a widedynamic range (less than 1% deviation over 3 to 4 orders ofmagnitude), which leads to simple, robust data analysis. Cathodeconstruction of the UV lamp determines the wavelengths availablefor analysis, making it possible to configure the Model 932 tomeasure many components that absorb UV/VIS energy.

The Model 932 uses only AMETEK-engineered, purpose-builtelectronics to ensure reliable performance under the harsh environ-mental conditions common in chemical and petrochemical facilities.These electronics provide concentration calculations, dataprocessing, temperature control, calibration and sophisticatedself-diagnostics.
