Questions and Answers

Q: During a brownfield turnaround you're tracing a separator level control loop using 2D CAD, and you search "separator level transmitter not matching P&ID elevation". The GA shows the LT nozzle at +1.2 m, but the P&ID instrument bubble ties it to the boot bottom. In service, the controller hunts and the dump valve slams. What's the root cause that explains all symptoms?

A: Principle: Level measurement depends on correct hydrostatic reference, not just signal tuning. Here the CAD discrepancy put the LT above the intended datum, so density and pressure changes look like level changes, driving valve slam during transients. Option B traps engineers who know tuning theory but miss that no amount of tuning fixes a biased measurement.

Q: You're updating a legacy P&ID in CAD and googling "control valve Cv change effect on downstream pressure". The upstream pressure is fixed by a compressor, and you replace a globe valve symbol with a higher Cv trim per redline. What happens downstream at steady state if the controller setpoint is unchanged?

A: Principle: In a closed loop, the controller adjusts valve position to meet the process variable. With fixed upstream pressure and same setpoint, the valve simply moves to a different opening to hold downstream pressure, provided it's not saturated. Option A catches people who think in open-loop terms and forget the controller action.

Q: While checking an old CAD P&ID you search "PSV shown on P&ID what hazards it does not protect against". The separator has a PSV to flare sized per API 520. During commissioning, the level controller fails high and liquid carries over to the gas outlet. What does the PSV NOT protect against here?

A: Principle: Relief devices limit pressure, not phase separation or inventory control. The PSV will lift on pressure rise, but it can't stop liquid from leaving with the gas when level control fails. Option A tempts engineers who associate any upset with relief, ignoring the pressure-only function.

Q: In a 2D CAD class exercise you type "difference between P&ID and GA drawing for equipment location". The P&ID shows instruments and control logic, while the GA shows nozzle elevations and footprints. Which statement fits actual engineering practice?

A: Principle: Different drawing types encode different information layers. Control intent comes from the P&ID, physical reality from the GA, and mismatches drive field errors if not reconciled. Option D attracts people burned by revision control who overgeneralize it.
