发明名称 DETECTION OF DISTILLATION COLUMN FLOODING
摘要 A method comprises sensing a differential pressure signal, filtering the differential pressure signal, generating a flooding indicator as a function of the filtered differential pressure signal, and indicating the onset of flooding. The differential pressure signal is sensed along a distillation flow path. The filtered differential pressure signal is responsive to a phase inversion along the flow path, and the flooding indicator is responsive to an onset of a flooding condition, based on the phase inversion. The onset of the flooding condition is indicated based on a change in the flooding indicator.
