Title:
SYSTEMS AND METHODS FOR DETERMINING A LEVEL OF FOULING OF COMPRESSORS
Document Type and Number:
WIPO Patent Application WO/2013/045540
Kind Code:
A3
Abstract:
A system and method is provided 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 (100). Based on the collected data, polytropic efficiency of the compressor is calculated (102). The estimated polytropic efficiency is normalized (104) to render the estimate more indicative of the degree of fouling (106).
