Fig. 21. Comparison of time-average temperature reading from thermocouples located at different axial points on the periphery of the carbon bed for periodic flow interruption and steady-state operation. Time-average u = 1.65 mm/s for flow interruption, r = 60 min and s = 0.5. Gas and liquid inlet temperature is about 26.5°C.

The AIChE (American Institute of Chemical Engineers) CCPS (Center for Chemical Process Safety) Process Equipment Reliability Database (PERD) initiative has rigorously identified and documented failure modes for instrument loops, which encompass control, indication, alarm, and automatic protection (Ref. 3). An excerpt from those lists shows a comparison of failure modes applicable to BPCS versus SIS (Figure 2-2). The ability of operations personnel to detect these failure modes is also quite different.
