Demonstration of non-linear model predictive control of post-combustion CO2 capture processes
Hauger, Svein Olav; Flø, Nina Enaasen; Kvamsdal, Hanne Marie; Gjertsen, Fredrik; Mejdell, Thor; Hillestad, Magne (Journal article; Peer reviewed, 2019)Nonlinear model predictive control applications have been deployed on two large pilot plants for post combustion CO2 capture. The control objective is formulated in such a way that the CO2 capture ratio is controlled at a ... -
Dynamic Real-Time Optimisation of a CO2 Capture Facility
Hotvedt, Mathilde; Hauger, Svein Olav; Gjertsen, Fredrik; Imsland, Lars Struen (Journal article; Peer reviewed, 2019)This work investigates economic optimisation of an energy-intensive amine regeneration process in a post-combustion CO2 capture plant, subject to a minimum CO2 capture ratio over 24 hours. A Dynamic Real-Time Optimisation ... -
Dynamic Real-Time Optimisation of an Amine-Based Post-Combustion CO2 Capture Facility using Single-Level Nonlinear Model Predictive Control
Hotvedt, Mathilde (Master thesis, 2018)A complete model of a CO2 capture facility has been optimised with the aid of Dynamic Real-Time Optimisation (DRTO) utilising single-level, Nonlinear Model Predictive Control to merge regulatory and economic objectives. ... -
Estimation in Large Mechanistic Models
Tusvik, Jannicke Selnes (Master thesis, 2011)The main objective in this thesis is to model an offshore processing plant, and adapt it to a given dataset by off-line parameter estimation and then perform an on-line state and parameter estimation. The aim is to use the ... -
Model predictive control of a polyolefin reactor
Linnestad, Kasper (Master thesis, 2015)Two models for the copolymerization of propylene and ethylene in a fluidized bed reactor (FBR) were developed. A simple model for control; and a more advanced model which served as both a replacement for logged industrial ... -
Short-Term Production Optimization in an Offshore Oil and Gas Processing Plant Using Nonlinear Model Predictive Control
Willersrud, Anders (Master thesis, 2010)The main objective in this thesis is to study how nonlinear model predictive control (NMPC) can be used directly for short-term production optimization. Here the objective to maximize the production is directly included ... -
Short-term production optimization of offshore oil and gas production using nonlinear model predictive control
Willersrud, Anders; Imsland, Lars Struen; Hauger, Svein Olav; Kittilsen, Pål (Journal article, 2013)The topic of this paper is the application of nonlinear model predictive control (NMPC) for optimizing control of an offshore oil and gas production facility. Of particular interest is the use of NMPC for direct short-term ...
