Patent number: 8216517Abstract: A control system includes an estimator configured to determine a present state of a device and compare the present state of the device with an expected state of the device. The control system further includes a predictor operatively coupled to the estimator, and configured to predict an event for execution by the device to reach the expected state of the device. The control system also includes a supervisory control unit operatively coupled to the predictor and the device, and configured to facilitate execution of the predicted event by the device.Type: GrantFiled: March 30, 2009Date of Patent: July 10, 2012Assignee: General Electric CompanyInventors: Vijaysai Prasad, Amol Rajaram Kolwalkar, Sunil Shirish Shah, Frederick Liberatore, Rajendra Naik

Patent number: 7818156Abstract: A method includes assessing corrosion in a refinery operation having a piping network. Assessing can include identifying in a petroleum sample a presence and an amount of a species determined to be potentially corrosive to corrodible equipment in a refinery. A corrosion risk presented by the presence, the amount, and the boiling point of the species is determined. And, the corrosion risk is evaluated in view of piping network information. A system for implementing the method is provided, also.Type: GrantFiled: November 5, 2007Date of Patent: October 19, 2010Assignee: General Electric CompanyInventors: Pramod Vachhani, Sunil Shirish Shah, Collin Wade Cross, Yatin Tayalia, Nishith Pramod Vora, Raghunandan Murthy

Patent number: 7455099Abstract: A technique is disclosed for evaluating and monitoring performance of a heat exchanger system. Operating parameters of the system are monitored and fouling factors for heat transfer surfaces of the exchanger are determined. Trending of fouling may be performed over time based upon the fouling factors, and a model of fouling may be selected from known sets of models, or a model may be developed or refined. Fluid treatment, such as water treatment regimes may be taken into account in evaluation of fouling. An automated knowledge based analysis algorithm may diagnose possible caused of fouling based upon sensed and observed parameters and conditions. Corrective actions may be suggested and the system controlled to reduce, avoid or correct for detected fouling.Type: GrantFiled: June 29, 2004Date of Patent: November 25, 2008Assignee: General Electric CompanyInventors: Mark David Osborn, Vijaysai Prasad, Lijie Yu, Venkatarao Ryali, Sunil Shirish Shah, Ivy Wai Man Chong, Shirley Suet-Yee Au, Nishith Pramod Vora
