Questions and Answers

Q: You're reading a P&ID and trying to reconcile line sizing during HAZOP. The long-tail phrase you're searching is "how to calculate control valve Cv from P&ID steam service". The P&ID shows a control valve on saturated steam at 10 barg, 180 °C, design flow 5,000 kg/h, with a noted allowable ΔP of 1.5 bar. Using IEC 60534 assumptions, what Cv should you expect to see on the valve datasheet?

Q: During an HSE walkdown you're asked to explain an alarm shown on the P&ID. The search phrase in your head is "P&ID level control valve fails open effect on separator". The inlet level control valve to a three-phase separator is marked FC. Instrument air pressure is lost. What happens next and what response aligns with the intent shown on the P&ID?

Q: You're on a COMAH site doing loop checks under audit pressure. The exact phrase you're googling is "P&ID loop check transmitter range mismatch datasheet". The P&ID shows PT-201 ranged 0–100 barg feeding a HH trip at 90 barg. In the field, the transmitter datasheet says calibrated 0–160 barg. What’s the correct action before sign-off?

Q: Reviewing a P&ID for a produced water system, you're thinking "carbon steel corrosion risk P&ID produced water CO2". The line is tagged CS, 60 °C, 3 barg, with dissolved CO₂ noted upstream. No corrosion allowance is shown. What degradation mechanism dominates?
