Optimization of an Absorption-Based Biogas Upgrading and Liquefaction Process
Hashemi, Sayed Ebrahim; Lien, Kristian Myklebust; Schnell, Sondre Kvalvåg; Austbø, Bjørn (Journal article; Peer reviewed, 2019)The present work proposes a methodology for optimization of a liquefied biomethane (LBM) production plant. The LBM production plant comprises amine-based absorption upgrading followed by a single expander refrigeration ... -
Overview of recent progress towards in-situ biogas upgradation techniques
Sarker, Shiplu; Lamb, Jacob Joseph; Hjelme, Dag Roar; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2018)Biogas, as derived from the anaerobic digestion process, offers a versatile possibility of renewable and sustainable energy usage. When enriched, upgraded biogas can yield high levels of biomethane, allowing its use as an ... -
Perspectives of optical colourimetric sensors for anaerobic digestion
Lamb, Jacob Joseph; Bernard, Olivier; Sarker, Shiplu; Lien, Kristian Myklebust; Hjelme, Dag Roar (Journal article; Peer reviewed, 2019)Although biogas is not a new approach to producing renewable fuel, it could further be developed to improve its potential as an alternative energy source. To achieve this, vast improvements in the efficiency and cost of ... -
Perspectives of surface plasmon resonance sensors for optimized biogas methanation
Lamb, Jacob Joseph; Bernard, Olivier; Sarker, Shiplu; Lien, Kristian Myklebust; Hjelme, Dag Roar (Journal article; Peer reviewed, 2019)Biogas production is becoming significantly viable as an energy source for replacing fossil‐based fuels. The further development of the biogas production process could lead to significant improvements in its potential. ... -
Potential role of sulfide precipitates in direct interspecies electron transfer facilitation during anaerobic digestion of fish waste
Hashemi, Seyedbehnam; Horn, Svein Jarle; Lamb, Jacob Joseph; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2022)Fish waste (FW) contains large amounts of protein and is a challenging feedstock for biogas production due to possible H₂S and ammonia generation. Adding FeCl3 to an anaerobic digester can precipitate H₂S. Mackinawite and ... -
Recirculating aquacultural system (RAS) wastewater treatment using microalgae
Kjos-Hanssen, Henriette Skaret (Master thesis, 2021)Avløpsvannet fra landbaserte oppdrettsanlegg inneholder næringsstoffer (f.eks. nitrogen og fosfor) som stammer fra uspist fiskefôr og avføring. Hvis dette avfallet slippes ut i økosystemer, kan næringsstoffene i vannet ... -
Stimulating biogas production from steam-exploded birch wood using Fenton reaction and fungal pretreatment
Hashemi, Seyedbehnam; Solli, Linn; Aasen, Roald; Lamb, Jacob Joseph; Horn, Svein Jarle; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2022)Delignification of steam-exploded birch wood (SEBW) was stimulated using a pretreatment method including Fenton reaction (FR) and fungi. SEBW was employed as a substrate to optimize the Fe(III) and Fe(II) dosage in FR. ... -
Thermodynamic analysis of different methanation reactors for biogas upgrading
Hashemi, Sayed Ebrahim; Lien, Kristian Myklebust; Schnell, Sondre Kvalvåg; Austbø, Bjørn (Peer reviewed; Journal article, 2020)Biomethane production from biogas can be increased by methanation of carbon dioxide with hydrogen through the Sabatier reaction. In this work, the performance of the methanation process is investigated under isothermal and ... -
Thermodynamic Insight in Design of Methanation Reactor with Water Removal Considering Nexus between CO2 Conversion and Irreversibilities
Hashemi, Sayed Ebrahim; Lien, Kristian Myklebust; Hillestad, Magne; Schnell, Sondre Kvalvåg; Austbø, Bjørn (Journal article; Peer reviewed, 2021)The inevitable nexus between energy use and CO2 emission necessitates the development of sustainable energy systems. The conversion of CO2 to CH4 using green H2 in power-to-gas applications in such energy systems has ... -
Yield improvements in anaerobic digestion of lignocellulosic feedstocks
Hashemi, Sayedbehnam; Sarker, Shiplu; Lamb, Jacob Joseph; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2020)The new EU bioenergy sustainability criteria demonstrate that bioenergy sustainability can be a challenge (Schlegel and Kaphengst, 2007). In 1990s, the energy crops were the main source for biogas production in Europa; ...
