Performance analysis of biocathode in bioelectrochemical CO2 reduction
(Peer reviewed; Journal article, 2019)Microbial electrosynthesis (MES) biogas upgrading is done via reduction of carbon dioxide to methane through electroactive microbial catalysis. The baseline MES mode of operation showed about a 39% increase in the methane ... -
Performance of CO2 flooding in a heterogeneous oil reservoir using autonomous inflow control
(Journal article; Peer reviewed, 2018)CO2-EOR is one of the main methods for enhanced oil recovery. The injection of CO2 does not only improve oil recovery, but also contributes to reduction of greenhouse gas emissions. However, many CO2-EOR project are reporting ... -
Performance of MAPA promoted tertiary amine systems for CO2 absorption: Influence of alkyl chain length and hydroxyl groups
(Journal article; Peer reviewed, 2017)Absorption and desorption of CO2 into five aqueous tertiary amine solvents and their blends with MAPA were studied using a screening apparatus. Results showed that MAPA significantly enhanced both CO2 absorption rate and ... -
Piping Components: An Analysis of the Critical Dimensions
(Peer reviewed; Journal article, 2020)Pipe components such as elbow, tees, and weldolets are produced at various places in the world. Although the component is produced in accordance with standard ASME (American Society of Mechanical Engineers) B16.9, measurements ... -
Prediction of void fraction and minimum fluidization velocity of a binary mixture of particles: Bed material and fuel particles
(Peer reviewed; Journal article, 2019)For operational control and design of a fluidized bed reactor containing different types of solid particles, the bed void fraction and minimum fluidization velocity are vital parameters. This paper demonstrates a method ... -
Pressure drop, flow pattern and local water volume fraction measurements of oil-water flow in pipes
(Journal article; Peer reviewed, 2009-11)Oil-water flow in horizontal and slightly inclined pipes was investigated. The experimental activities were performed using the multiphase flow loop at Telemark University College, Porsgrunn, Norway. The two-fluid model ... -
Proceedings of the Tenth International Seminar on Fire and Explosion Hazards, 22-27 May 2022, Oslo, Norway
(Conference object; Peer reviewed, 2022)The Tenth International Seminar on Fire and Explosion Hazards (ISFEH10) organized in Oslo, Norway from 22 to 27 May 2022, is a place to share research on the physical effects of hazards, prediction methods for consequences, ... -
Process Design of a Novel Low Temperature Methanol Synthesis Process Using an Air-blown Autothermal Reformer
(Journal article; Peer reviewed, 2018)Methanol (MeOH) synthesis at low temperature (100 oC) presents an opportunity for full syngas conversion per pass. This presents a cheaper alternative for MeOH synthesis using an air-blown autothermal reformer (ATR) rather ... -
Process Integration of Green Hydrogen: Decarbonization of Chemical Industries
(Peer reviewed; Journal article, 2020)Integrated water electrolysis is a core principle of new process configurations for decarbonized heavy industries. Water electrolysis generates H2 and O2 and involves an exchange of thermal energy. In this manuscript, we ... -
Process parameters affecting the sustainability of fermentative hydrogen production: A short review
(Journal article; Peer reviewed, 2011)Anaerobic fermentation is regarded as the least energy intensive method for H2 production. Extensive literature on experimental attempts to achieve the highest possible theoretical yield (e.g. 4 mol H2/mol glucose) is ... -
Process Simulation of Calcium Looping With Indirect Calciner Heat Transfer
(Conference object; Peer reviewed, 2015-11-25)In calcium looping (CL), calcium oxide (CaO) is used as a sorbent for carbon dioxide (CO2). The CO2 reacts with CaO to produce calcium carbonate (CaCO3) in a carbonator operating at about 650 °C. The CaCO3 is then sent to ... -
Pyrolysis of plastic waste to environmental friendly products
(Journal article; Peer reviewed, 2020)Pyrolysis of plastics is one of the efficient ways to recover plastic waste. Pyrolysis refers to a thermal degradation of long-chain organic molecules into smaller hydrocarbons. Many ongoing research studies are trying to ... -
Quantification of biofilm accumulation by an optical approach
(Journal article; Peer reviewed, 2001-02)Methods for non-invasive, in situ, measurements of biofilm optical density and biofilm optical thickness were evaluated based on Pseudomonas aeruginosa experiments. Biofilm optical density, measured as intensity reduction ... -
Raman Spectroscopy as an Online Monitoring Tool for CO2 Capture Process: Demonstration Using a Laboratory Rig
