Dynamic Model of an Ammonia Synthesis Reactor Based on Open Information
Jinasena, Asanthi; Lie, Bernt; Glemmestad, Bjørn (Chapter; Peer reviewed, 2016)Ammonia is a widely used chemical, hence the ammonia manufacturing process has become a standard case study in the scientific community. In the field of mathematical modeling of the dynamics of ammonia synthesis reactors, ... -
Modelling and control of a typical high head hydropower plant
Zhou, Wenjing; Lie, Bernt; Glemmestad, Bjørn (Conference object; Peer reviewed, 2011)This paper describes an effective mathematical model of a hydropower plant and how a decentralized control strategy for frequency and terminal voltage can be simulated. Several dynamic equations are presented for each ... -
Optimal control strategies with nonlinear optimization for an Electric Submersible Pump lifted oil field
Sharma, Roshan; Glemmestad, Bjørn (Journal article; Peer reviewed, 2013)In an Electric Submersible Pump (ESP) lifted oil field, the ESP of each oil well should be operated inside its operating window. The total power consumed by the ESPs in the oil field should be minimized. The speed of the ... -
Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem.
Sharma, Roshan; Fjalestad, Kjetil; Glemmestad, Bjørn (Journal article; Peer reviewed, 2012)Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a field with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally ... -
Population balance modelling for fertilizer granulation process
Vesjolaja, Ludmila; Glemmestad, Bjørn; Lie, Bernt (Journal article; Peer reviewed, 2018)Few granulation plants are operated optimally. It is common to operate granulation plants below their maximum design capacity, and in many cases, periodic instabilities may also occur. From a process control and optimization ...
