© Siemens AG 2015 Continuous Gas Analyzers, extractive SIPROCESS UV600 1 ■ Overview ■ Application The function of the SIPROCESS UV600 gas analyzer is based on UV resonance absorption spectrometry. It also is used to measure very low NO, NO2, SO2 or H2S concentrations in gases. ■ Benefits • For NO, NO2, SO2: Very low cross-sensitivity with other gases • All modules are thermostatically-controlled, and thus independent of the ambient temperature • Simultaneous measurement of NO and NO2 with subsequent calculation of total. Therefore neither an NO2 converter nor a CLD analyzer is required. • Measurement in the UV range: - No cross-sensitivity with H2O and CO2 - Very low SO2 and NO measuring ranges possible • UV resonance absorption spectrometry: - Measurement of very low NO concentrations - Very low cross-sensitivity possible • Very long service life of UV lamp (usually 2 years) • Low drifts and high stability thanks to four-channel measuring method with double generation of quotient • True reference measurement for low-drift, stable results • Interface for remote monitoring in networks and linking to process control systems • Optional calibration unit - Filter wheel with calibration cells which can be automatically swung into the optical path - Low consumption of calibration gas - Manual or automatic calibration possible 1/232 Siemens AP 01 · 2015 Fields of application • Emission measurements - Measurement of low NO concentrations in power plants or gas turbines - Monitoring of NOx in denitrification plants by direct measurement of NO and NO2, as well as summation to NOx in the analyzer - Efficient measurement in desulfurization plants - Monitoring of very small SO2 and NO concentrations - Emission measurements in the paper and cellulose industries • Process monitoring - Measurement of SO2 in process gases in the paper and petrochemical industries - Optimization of NOx emissions in exhaust gas in the automotive industry - H2S and SO2 measurements in the residual gas purification of sulfur recovery units • H2S measurement - In typical emission applications - Taking account of possible cross-sensitivities (e.g. from mercaptan) Special versions Special applications In addition to the standard combinations, special applications are also available upon request, e.g. as regards the material in the gas path and the sample chambers. © Siemens AG 2015 Continuous Gas Analyzers, extractive SIPROCESS UV600 1 ■ Design • 19" rack unit with 4 HU for installation - in hinged frame - in cabinets with or without telescopic rails • Internal gas paths: hose made of FKM (VitonTM) or pipe made of PTFE or stainless steel • Gas connections for sample gas inlet and outlet and for reference gas: fittings, pipe diameter of 6 mm or ¼" Inputs and outputs • 2 configurable analog inputs • 4 configurable analog outputs • 8 digital inputs • 8 digital outputs Display and control panel • Large LCD panel for simultaneous display of measured value and device status • Sensor buttons with context-based functions • Display protected by glass pane • Contrast of the LC display can be adjusted Connection via SIPROCESS-UV600-specific software tool Communications Materials wetted by sample gas Component Material Analyzer unit (sample chamber) Aluminum or stainless steel mat. no. 1.44041), epoxy resin Optical window CaF2 or quartz1), epoxy resin Gas path, gaskets FKM (Viton), PTFE, stainless steel mat. no. 1.45711) Chamber Aluminum or stainless steel1) Gas inlet/outlet PVDF, stainless steel, mat. no. 1.44011) Moisture sensor Stainless steel mat. no. 1.4571, platinum, epoxy resin Diaphragm pump • Central body • Diaphragm 1) PVDF FKM (Viton), EPDM Depending on the version SIPROCESS UV600, display and control panel Gas flow chart o Filter (optional) Moisture sensor (optional) Sample gas inlet Sample gas outlet UV module SIPROCESS UV600, gas flow chart Siemens AP 01 · 2015 1/233 © Siemens AG 2015 Continuous Gas Analyzers, extractive SIPROCESS UV600 1 ■ Mode of operation The measuring principle of the SIPROCESS UV600 is based on the molecule-specific absorption of gases in the ultraviolet wavelength range. Radiation of a wavelength appropriate to the measurement is passed through the sample, and the selective absorption which is proportional to the concentration of the measured component is determined. Measuring method An electrodeless discharge lamp (1) emits broadband in the ultraviolet spectral range. A filter wheel unit (2) generates the ultraviolet radiation suitable for the respective measured component. Either interference filter correlation (IFC) or gas filter correlation (GFC), or a combination of the two methods, can be used for this purpose. Interference filter correlation (IFC) The sample and reference radiations are generated alternately with two different interference filters being swung into the beam path (filter wheel 2a). Gas filter correlation (GFC) Especially when NO is the measured component, the reference radiation is generated by swinging in a gas filter which is filled with the associated gas (filter wheel 2b). IFC and GFC The two filter wheels are combined in order to measure NO in combination with other measured components. Design of the analyzer module After passing through the filter unit, the beam is directed via a lens (3), a beam divider (4) and a mirror (4) into the sample chamber (6) and reference chamber (7). The sample beam passes through the sample chamber (6), into which sample gas flows, and its intensity is weakened in line with the concentration of the measured component. The reference beam is directed via a mirror (5) into the reference chamber (7). This is filled with a neutral gas. The detectors (9) receive the sample and reference beams in succession. These measured signals are amplified and evaluated using electronics. The measuring system is temperature-controlled to minimize external temperature influences. The physical state of the measuring system is recorded simultaneously through time-offset detection of the reference beam, and compensated if necessary. A quotient is generated for each detector from the determined signal values, and the ratio of these quotients determined. This double generation of quotients means that symmetrical signal drifts are compensated in the best possible manner in addition to proportional signal drifts. Note The sample gases must be fed into the analyzers free of dust. Condensation in the sample chambers must be prevented. Therefore, the use of gas modified for the measuring task is necessary in most application cases. Additional measures depending on the application must be taken when introducing gases with flammable components at concentrations above the lower explosive limit (LEL). Please contact the technical department in such cases. 1/234 Siemens AP 01 · 2015 © Siemens AG 2015 Continuous Gas Analyzers, extractive SIPROCESS UV600 1 ■ Function M IFC 2a M 2a 2b GFC 2b M IFC + GFC M 1 M 10 2a 2b 2 3 M M 6 8 4 9 7 8 9 5 1 2 2a 2b 3 4 UV lamp Filter wheel unit Filter wheel 1 Filter wheel 2 Collimator lens Beam divider 5 6 7 8 9 10 Mirror Sample chamber Reference chamber Focus lens Detector Optional calibration unit GFC Gas filter correlation IFC Interference filter correlation M Motor SIPROCESS UV600, operating principle Siemens AP 01 · 2015 1/235 © Siemens AG 2015 Continuous Gas Analyzers, extractive SIPROCESS UV600 1 ■ Technical specifications General information Measuring ranges Electrical characteristics Line voltage (optional, see nameplate) 93 ... 132 V AC, 186 ... 264 V AC Line frequency (AC) 47 ... 63 Hz Permissible overvoltages (transient surges in the power supply network) Up to overvoltage category II in accordance with IEC 60364-4-443 Power consumption Approx. 50 VA, max. 300 VA EMC interference immunity (electromagnetic compatibility) Dependent on order configuration NO, NO2, SO2: 0 … 300 to 0 ... 1 000 vpm H2S: 0 … 500 to 0 ... 1 000 vpm In accordance with EN 61326-1, EN 61326-2-1, EN 61000-6-2, EN 61000-6-4 and EU Directive 2004/108/EC.
