  • Method and system for diagnosing compressors
    Patent number: 9709980
    Abstract: Method, system and computer software for diagnosing a compressor. The method includes generating a feature vector of the compressor, the feature vector of the compressor including components describing states of various parts of the compressor; determining, based on fuzzy constraints, an aggregated anomaly vector corresponding to the feature vector; defining rules for a preset list of possible faults/failure modes of the compressor; calculating a corroborating measure between the aggregated anomaly vector and the rules; and identifying a fault/failure mode of the compressor based on a result of the corroborating measure.

  • SYSTEMS AND METHODS FOR DETERMINING A LEVEL OF FOULING OF COMPRESSORS
    Publication number: 20140229121
    Abstract: A system and a method for determining a degree of fouling formation in a compressor, e.g., in an ethylene production unit or other application. Data associated with the operation of the compressor is collected. Based on the collected data, polytropic efficiency of the compressor is calculated. The estimated polytropic efficiency is normalized to render the estimate more indicative of the degree of fouling.
