Latest Patents

Thomas W S Lewis holds a patent for a "Computer system and method for the dynamic construction and online deployment of an operation-centric first-principles process model for predictive analytics." This patent describes computer-implemented methods and systems that construct a calibrated operation-centric first-principles model suitable for online deployment. The model is designed to monitor, predict, and control real-time plant operations. The methods identify a plant-wide first-principles model configured for offline use and select a modeled operating unit contained in the plant-wide model. They convert the plant-wide model to an operation-centric first-principles model of the selected unit and recalibrate it using real-time measurements collected by physical instruments. The recalibration includes reconciling flow and temperature, estimating feed compositions, and tuning liquid and vapor traffic flow in the model. The operation-centric model is then deployed to calculate Key Performance Indicators (KPIs) using real-time measurements, allowing for automatic predictions and control of the physical operating unit.
