Centrifugal Compressors
Centrifugal compressors play a pivotal role in the oil and gas Industry. They are central to the liquefaction of natural gas in LNG plants and the manufacture of ethylene, ammonia, and methanol in petrochemical facilities. They support gas injection to enhance oil recovery, maintain pipeline pressures, and handle synthesis gases used in refining processes.

Challenges
A significant challenge is the unpredictability of failures, such as surge events and dry gas seal failures that are often not captured by traditional monitoring methods until damage has already occurred. Research suggests that a considerable percentage of centrifugal compressor failures occur without adequate early warning, complicating maintenance schedules. Predicting these failures is essential yet challenging due to the complex interplay of gas compositions, pressure variations, and dynamic load changes.
Preventing the issue
The Turbomechanica platform addresses these challenges by integrating physics-based performance models with multivariate machine learning models, univariate anomaly detection, and dynamic thresholding. This approach allows the creation of comprehensive digital twins that model thermodynamic performance and mechanical machine behavior. Combining information from these algorithms, Turbomechanica's diagnostics engine can detect a large universe of equipment issues typically months before failure.
