A numerical solution strategy for dynamic simulation of post-combustion CO2 capture
Enaasen, Nina; Tobiesen, Finn Andrew; Kvamsdal, Hanne Marie; Hillestad, Magne (Journal article; Peer reviewed, 2013)This paper describes in detail the numerical solution of a dynamic process developed for post-combustion absorption based CO2 capture. The method used in this work is sequential modular integration. This means that each ... -
A systematic procedure for process energy evaluation for post combustion CO2 capture: Case study of two novel strong bicarbonate-forming solvents
Tobiesen, Finn Andrew; Haugen, Geir; Hartono, Ardi (Journal article; Peer reviewed, 2018)Process simulation is used for energetic evaluation of two novel strong bicarbonate forming solvents for post combustion CO2 capture, intended for coal- and natural gas based exhaust streams. An evaluation framework has ... -
Applicability of enhancement factor models for CO2 absorption into aqueous MEA solutions
Putta, Koteswara Rao; Tobiesen, Finn Andrew; Svendsen, Hallvard Fjøsne; Knuutila, Hanna K (Journal article, 2017)In many chemical industrial processes, mass transfer across gas-liquid interfaces accompanied by chemical reaction is the governing phenomena. In case of mass transfer accompanied by a chemical reaction in the liquid phase, ... -
An approach for VLE model development, validation, and implementation in Aspen Plus for amine blends in CO2 capture: the HS3 solvent case study
Gilardi, Matteo; Bisotti, Filippo; Tobiesen, Finn Andrew; Knuutila, Hanna Katariina; Bonalumi, Davide (Journal article; Peer reviewed, 2023)Carbon Capture and Storage (CCS) using chemical absorption is a viable method to significantly cut CO2 emissions in the industrial and energy sectors. However, further development of improved absorbents is necessary to ... -
Aspen Plus ENRTL Model for HS3 Blend, a Novel Solvent for CO2 Capture
Gilardi, Matteo; Bisotti, Filippo; Knuutila, Hanna Katariina; Tobiesen, Finn Andrew; Bonalumi, Davide (Peer reviewed; Journal article, 2023)Carbon Capture and Storage (CCS) is among the main available options to cut CO2 emissions from the industry and energy production sectors, but the high costs of current CCS technology still limit their large-scale ... -
Demonstration of non-linear model predictive control for optimal flexible operation of a CO2 capture plant
Mejdell, Thor; Kvamsdal, Hanne Marie; Hauger, S.O.; Gjertsen, Fredrik; Tobiesen, Finn Andrew; Hillestad, Magne (Peer reviewed; Journal article, 2022)Due to the penetration of renewable intermittent energy, there is a need for coal and natural gas power plants to operate flexibly with variable load. This has resulted in an increasing interest in flexible and operational ... -
Dynamic modeling of the solvent regeneration part of a CO2 capture plant
Enaasen, Nina; Tobiesen, Finn Andrew; Kvamsdal, Hanne Marie; Hillestad, Magne (Journal article; Peer reviewed, 2013)In this work, a system of unit operations is modeled and implemented in MATLAB for dynamic simulation of the regeneration part of the CO2 capture process. The system consists of a stripper, a reboiler and a condenser, and ...
