What is oxidation catalyst?

Oxidises CO and formaldehyde at operating temperature 380–450 °C; Delta-T over the catalyst (typically 10–30 °C due to exothermic reaction) indicates activity — Delta-T close to 0 signals deactivation or H2S poisoning.

What the AI reads from these values

What the AI reads
  • Delta-T over the catalyst as an indicator for the exothermic reaction rate
  • Deviation from setpoint (380–450 °C) to detect temperature gradients
  • Monitoring of Delta-T stability to identify H2S poisonings
  • Trend analysis of the exhaust gas flow to predict catalyst deactivation
Scenario

Monitored: continuous

The scenario: an emission value creeps slowly upwards, is only noticed during the official measurement, in the worst case leading to operational restrictions. The AI: detects the trend towards the limit early and reports a need for action before the measurement occurs. It identifies the trend before the limit is exceeded.

Why this matters

Precise monitoring of catalyst activity prevents unplanned downtime due to exceeding emission limits. The identification of deactivation enables planned maintenance intervals instead of emergency shutdowns. A stable Delta-T metric ensures the long-term integrity of the exhaust gas treatment system. Measured value (mg/m³) · Limit value (mg/m³) → — % reserve to limit Calculation path: (Limit value − Measured value) ÷ Limit value × 100
