Online Raman Analytics for Smarter C8 Aromatics Management
Modern petrochemical plants need more than accurate analytical
results. They need analytical information at the right time.
For PX production, concentration changes inside an adsorption
system can influence operating decisions long before the next
laboratory result becomes available.
JINSP RS2000PAT Online Raman Analyzer is designed to provide
continuous, in-situ composition information directly from the
process.
A Real-Time View of the Adsorption Process
In C8 aromatic separation, PX, MX, OX and EB coexist in the process
stream. The adsorption separation process continuously changes the
concentration distribution of these components.
Instead of relying solely on periodic sampling, Raman probes can be
installed at strategic positions in the adsorption tower.
The analyzer continuously collects Raman spectra and converts the
spectral information into quantitative process data.
This provides a more immediate view of:
- PX concentration
- Component concentration changes
- Concentration distribution
- Process trends
- Abnormal changes
Connect Analysis with Plant Control
RS2000PAT supports communication through RS485 and RJ45 Ethernet
interfaces with Modbus protocol. This allows analytical data to be
integrated into DCS and other industrial control architectures.
The PX application specifically uses real-time measurement feedback
to support process-parameter adjustment.
Designed for Continuous Monitoring
The analyzer incorporates automatic calibration, self-diagnosis,
thermal control and positive-pressure protection. Its
explosion-proof cabinet configuration is designed for continuous
operation in industrial environments from -20 to 50°C.
This makes the system suitable for applications where analytical
equipment must remain available around the clock rather than being
operated only during laboratory testing.
PX Measurement Performance
In the demonstrated application, the PX quantitative deviation is
reported at less than 0.07%.
With continuously updated composition information, process teams
can use real-time analytical data to support:
Faster response — detect concentration changes without waiting for a laboratory
cycle.
Process optimization — adjust operating parameters based on current process conditions.
Adsorbent management — evaluate concentration profiles and optimize operating cycles.
Lower sampling workload — reduce reliance on repetitive manual sampling and laboratory
analysis.
