Real-Time Optimization under Uncertainty Applied to a Gas Lifted Well Network
Krishnamoorthy, Dinesh; Foss, Bjarne Anton; Skogestad, Sigurd (Journal article; Peer reviewed, 2016)In this work, we consider the problem of daily production optimization in the upstream oil and gas domain. The objective is to find the optimal decision variables that utilize the production systems efficiently and maximize ... -
Slug handling with a virtual harp based on nonlinear predictive control for a gravity separator
Backi, Christoph Josef; Krishnamoorthy, Dinesh; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)This paper presents a nonlinear model predictive control approach for a three-phase gravity separator model. The aim of the controller is to dampen slug-induced, oscillatory disturbances in the inflow to the gravity ... -
Steady-State Real-time Optimization using Transient Measurements
Krishnamoorthy, Dinesh; Foss, Bjarne Anton; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)Real-time optimization (RTO) is an established technology, where the process economics are optimized using rigourous steady-state models. However, a fundamental limiting factor of current static RTO implementation is the ... -
Systematic design of active constraint switching using se-lectors.
Krishnamoorthy, Dinesh; Skogestad, Sigurd (Peer reviewed; Journal article, 2020)Selector logic is a simple and effective tool to switch between different controlled variables associated with change in active constraints. Selector blocks have been extensively used in the process control industry for ...
