Evidence Notes
Heated-wetted-parts SO₂/NOₓ analyzer for tail-gas process control
Application note based on the existing sulfur-recovery scenario: fast-response UV and CLD measurement with heated wetted parts supports air-injection control review at the tail-gas incinerator outlet. Control-loop behavior depends on sample transport, DCS tuning, and local emission program requirements.

01 Measurement Principle and Limits
How the measurement is bounded
This is a dual-platform package: the ZS6200 platform measures SO₂ by UV fluorescence (UVF) using pulsed UV excitation, while the ZS6100 platform measures NOₓ by chemiluminescence (CLD) for process-control feedback. SO₂: UVF on ZS6200. NOₓ: CLD on ZS6100.
Requires
- Heated wetted parts when condensation risk is present
- Integrated sample conditioning or a compatible sampling system for high-moisture duty
- Configured analog or digital output mapping for DCS control loops
Interferents and Limits
- H₂O vapor when the sample is not kept above condensation conditions
- CO₂ continuum/background absorption where UV optical compensation is site-configured
- Particulate matter that reaches the optical path without filtration
- Very high moisture service without ZS-SCS-800 or equivalent heated sampling review
- Sample pressure outside the stated specifications range
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Very high moisture sample without heated sampling system review
- Sample pressure outside stated process inlet range
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- heated wetted parts to 200°C
- integrated sample conditioning
- 19-inch rack or wall-mount analyzer
- Very high moisture service should be reviewed against the ZS-SCS-800 heated sampling path stated in FAQ

07 Application Evidence
Application context from complex industrial environments.
Application Context
Sulfur recovery units need <5 s SO₂ response at the Claus tail-gas incinerator outlet to enable real-time air-injection control, but standard analyzers introduce sampling delays that prevent closed-loop tuning.
Architecture Response
The ZS6200 UVF SO₂ channel paired with the ZS6100 CLD NOx channel, configured with heated wetted parts, supports fast process-control feedback so the DCS can adjust air injection and support tighter tail-gas SO₂ control aligned with regional emission limits. Response time is configured per application (datasheet pending).
Frequently Asked Questions
Why is fast response time important for process control?
In FGD and SCR control loops, sub-5-second response allows the DCS to adjust reagent dosing before process excursions reach the stack. Slower analyzers cause oscillation and reagent waste.
Can it handle high-moisture samples?
Yes, the heated wetted parts (200°C) reduce condensation risk. For very high moisture (>40% H₂O), pair with the ZS-SCS-800 heated sampling system.
What are the detection principles for SO₂ and NOₓ?
This is a dual-platform package. SO₂ is measured by UV fluorescence (UVF) on the ZS6200 platform: pulsed UV light excites SO₂ molecules, which emit fluorescent light proportional to concentration. NOₓ is measured by chemiluminescence (CLD) on the ZS6100 platform. Each channel manages matrix effects through optical filtering and calibration.
What outputs does it support?
2×4-20mA isolated analog, Modbus RTU/TCP, and HART 7. Optional OPC-UA gateway available for Industry 4.0 integration.
Is it suitable for Claus tail gas applications?
Yes, specifically designed for SRU monitoring with heated wetted parts and materials resistant to sulfur compounds (SS316L/Hastelloy optional).
