Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS
(Journal article; Peer reviewed, 2018)Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ... -
Simulation of dew points in raw biogas using PR and SRK equations of state :
(Peer reviewed; Journal article, 2019)Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ... -
Simulation of enhanced oil recovery with CO2 injection
(Journal article; Peer reviewed, 2019)One of the goals of the Paris Agreement is to reduce the CO2 emission to the atmosphere. This paper deals with CO2-EOR, which is a good option for utilizing and storing CO2. Four cases were simulated using the commercial ... -
Simulation of entrained flow gasification reactor with Multi Phase Particle in Cell (MP-PIC) approach
(Journal article; Peer reviewed, 2020)An Entrained flow gasification reactor is studied in this work. Entrained flow reactors are best suited for a feed with small particles at large capacity, at high temperatures, pressures and with short residence time. This ... -

Simulation of Gasification of Livestock Manure with Aspen Plus
(Conference object; Peer reviewed, 2015-11-25)Gasification is a flexible technology where all types of organic waste including biomass from manure can be used as feed to the reactor. The recovery of energy from solid waste offers several benefits including substantial ... -
Simulation of improved absorption configurations for CO2 capture
(Conference object; Peer reviewed, 2015-11-25)The most well-known technology for post combustion CO2 capture from exhaust gas is absorption in an amine-based solvent followed by desorption. The drawback of this method is the high heat consumption required for desorption. ... -
Simulation of Oil Production from Homogenous North Sea Reservoirs with Inflow Control using OLGA/Rocx
(Journal article; Peer reviewed, 2017)Advances in drilling technology have made long, horizontal wells the preferred method to extract oil from reservoirs in the Norwegian Sector. Early water or gas breakthrough is a passive inflow control devices (ICD) are ... -
Simulation of Simplified Model for Reaction Kinetics in Biomass Gasification
(Conference object; Peer reviewed, 2015-11-25)Due to complexity in interactions between solid particles and between particles and carrier fluid, modeling of biomass gasification kinetics has been shown to be very challenging. Some commercial packages such as Barracuda ... -
Simulation of the Effect of Local Electric Potential and Substrate Concentration on CO2 Reduction via Microbial Electrosynthesis
(Peer reviewed; Journal article, 2022)Integrating anaerobic digestion into electrochemical reactors is an advanced technology for biomethane recovery. Imposing low electric potential between electrodes, supplies CO2, electrons, and hydronium ions from anodic ... -
Simulation of the Pyrolysis Process: from Plastic Waste to Environmental Friendly Fuel
(Journal article; Peer reviewed, 2018)How to deal with plastic waste is an important question, as it may affect both the climate and environment. A method that may be beneficial to dispose some kinds of plastic waste that cannot be material-recycled is ... -
Simulation of Transcritical Flow in Hydraulic Structures
(Journal article; Peer reviewed, 2015-11-25)In hydraulic engineering, transcritical flows are often required in some applications. One example is in a Venturi channel where the occurrence of critical depth is used to estimate flow rate in the channel. In this paper, ... -
Simulations and real applications of PI and MPC averaging level control in a water resource recovery facility
(Journal article; Peer reviewed, 2018)The basin level control system in an existing wastewater treatment plant is designed for two different operation modes: compliant level control for smooth pump flow, and stiff level control. Both a model-based predictive ... -
Simulations at work — a framework for configuring simulation fidelity with training objectives
(Peer reviewed; Journal article, 2019)This study aims to provide framework for considering fidelity in the design of simulator training. Simulator fidelity is often characterised as the level of physical and visual similarity with real work settings, and the ... -
