Applicability of enhancement factor models for CO2 absorption into aqueous MEA solutions
Putta, Koteswara Rao; Tobiesen, Finn Andrew; Svendsen, Hallvard Fjøsne; Knuutila, Hanna K (Peer reviewed; 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 (Peer reviewed; Journal article, 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 ... -

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 (Peer reviewed; Journal article, 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 ... -
Energy assessments of onboard CO2 capture from ship engines by MEA-based post combustion capture system with flue gas heat integration
Einbu, Aslak; Pettersen, Torbjørn; Morud, John; Tobiesen, Finn Andrew; Jayarathna, Chameera; Skagestad, Ragnhild; Nysæther, Gisle (Peer reviewed; Journal article, 2022)An early phase feasibility study was carried out for offshore CO2 capture from ship engines of a CO2 transport ship. A flexible in-house process simulator was applied in the assessments. Parametric studies of the overall ... -
A numerical solution strategy for dynamic simulation of post-combustion CO2 capture
Enaasen, Nina; Tobiesen, Finn Andrew; Kvamsdal, Hanne Marie; Hillestad, Magne (Peer reviewed; Journal article, 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 ... -
