Chemical Process Troubleshooting & Root Cause Analysis
Diagnose chemical process failures and identify root causes systematically
What You Can Do
You can systematically analyze process upsets, equipment failures, and quality issues to pinpoint root causes and recommend corrective actions. This skill guides you through structured troubleshooting methodologies, evaluates process parameters against specifications, and identifies safety risks associated with failures. You'll generate documentation suitable for incident reports and continuous improvement initiatives.
Features
Systematically map failure symptoms to potential causes using FMEA and fault tree logic
Diagnose deviations in temperature, pressure, flow rate, composition, and other critical process parameters
Apply the 5-Why method and fishbone diagrams to trace problems back to fundamental causes
Evaluate hazards created by the failure, including runaway reactions, toxic release, or equipment damage
Troubleshoot instrument drift, fouling, corrosion, mechanical wear, and instrumentation failures
Generate immediate containment steps and long-term preventive measures with priority ranking
Produce formatted incident reports, investigation summaries, and audit-ready documentation
Example Output
Failure: Batch reactor temperature spike to 95°C (setpoint 75°C) over 2 minutes.
Initial Findings: Thermocouple calibration within spec. Cooling water flow normal. Heating element contactor verified.
Root Cause: Exothermic impurity reaction. Grade B feedstock sample tested positive for 1.2% reactive ketone (spec limit 0.05%).
Safety Risk: Runaway reaction risk if temperature reaches 120°C; pressure relief set at 3.5 bar. Immediate action required.
Corrective Actions:
- Immediate: Return batch to safe state, increase cooling flow by 20%, reduce feed rate by 50%
- Short-term: Tighten vendor QC testing, conduct COA audits for 12 prior batches
- Long-term: Install inline UV-Vis feedstock analyzer; update batch hold procedure
Impact: Prevents 3-5 day production loss and mitigates explosion risk.
