Patent number: 10481018Abstract: Embodiments of the disclosure relate to systems and methods to evaluate performance of a fluid transport system. Towards this end, a performance report of the fluid transport system can be generated by estimating various performance parameters at an outlet of a heat exchanger in lieu of using sensor data obtained directly from the outlet of the heat exchanger. Specifically, in one exemplary implementation, sensor data is obtained from an inlet of the heat exchanger and an outlet of a downstream element that is coupled to the heat exchanger, for estimating the various performance parameters at the outlet of the heat exchanger. The estimated performance parameters can then be combined with empirical data and predictive data for generating the performance report of the fluid transport system.Type: GrantFiled: April 19, 2016Date of Patent: November 19, 2019Assignee: General Electric CompanyInventors: Awadesh Kumar Tiwari, Arul Saravanapriyan, Gunaranjan Chaudhry, Nimmy Paulose

Patent number: 10088839Abstract: A system and computer-implemented method for generating real-time performance advisories for a centrifugal compressor of a fleet of centrifugal compressors are provided. The method includes receiving an actual thermodynamic signature of the compressor, that is unique to the compressor, receiving compressor process parameter values during operation of the compressor, determining, in real-time, an actual performance of the compressor using the compressor process parameter values, determining, in real-time, a predicted performance of the compressor using the received actual thermodynamic signature of the compressor, determining a performance deviation of the compressor using the actual performance and the predicted performance, comparing the performance deviation to a predetermined dynamic threshold range of performance deviation specific to operating speed, and generating a notification to a user using the comparison.Type: GrantFiled: March 1, 2013Date of Patent: October 2, 2018Assignee: Nuovo Pignone SrlInventors: Arul Saravanapriyan, Pier Luigi Di Pillo, Osama Naim Ashour, Giuseppe Stringano, Abdurrahman Abdallah Khalidi
