Abstract
A method of monitoring a turbomachinery system is disclosed herein. The method includes measuring a pressure drop across an intake filter. The method further includes determining clog rate parameters for a clog rate of a filter area of the intake filter based on the measured pressure drop across the intake filter. The method yet further includes predicting an intake filter life cycle of the intake filter by predicting a pressure drop across the intake filter for the intake filter life cycle based on the determined clog rate parameters, and providing a recommended time to service the intake filter to an operator of the turbomachinery system based on the predicted intake filter life cycle.
