    • Biological treatment of amine wastes generated in post combustion CO2 capture 

      Botheju, Deshai; Li, Yuan; Hovland, Jon; Haugen, Hans Aksel; Bakke, Rune (Journal article; Peer reviewed, 2011)
      The wastes generation by amine degradation is an important issue to be addressed when considering CCS schemes. Biological treatment of amine wastes can be a strategy with reasonable economy and environmental sustainability. ...

    • Compression and transport of raw biogas 

      Hovland, Jon; Øi, Lars Erik (Lecture, 2019)

    • Detoxifying CO2 Capture Reclaimer Waste by Anaerobic Digestion 

      Wang, Shuai; Hovland, Jon; Brooks, Steven (Journal article; Peer reviewed, 2013-10-13)
      The decrease in toxicity of carbon capture reclaimer monoethanolamine (MEA) waste (MEAw) during anaerobic degradation of such waste together with easily degradable organics was investigated. Samples were collected from a ...

    • Efficiency of the anaerobic digestion of amine wastes 

      Wang, Shuai; Hovland, Jon; Bakke, Rune (Journal article; Peer reviewed, 2013-08-04)
      Laboratory-scale anaerobic degradation of monoethanolamine waste (MEAw) with co-substrate organics was conducted at roomtemperature and organic loading rates from 0.19 to 5.03 kg COD/m3 day for 486 days in a hybrid digester. ...

    • Modeling and simulation of lab-scale anaerobic co-digestion of MEA waste 

      Wang, Shuai; Hovland, Jon; Bakke, Rune (Journal article; Peer reviewed, 2014)
      Anaerobic digestion model No.1 (ADM1) was applied and expanded in this study to model and simulate anaerobic digestion (AD) of an industrial carbon capture reclaimer MEA (monoethanolamine) waste (MEAw) together with easily ...

    • Optimal design and operation of a UASB reactor for dairy cattle manure 

      Haugen, Finn; Bakke, Rune; Lie, Bernt; Hovland, Jon; Vasdal, Knut (Journal article; Peer reviewed, 2015-02-01)
      Optimal design and operation of a planned full-scale UASB reactor at a dairy farm are determined using optimization algorithms based on steady state simulations of a dynamic AD process model combined with models of the ...

    • Simulation of Condensation in Biogas containing Ammonia 

      Øi, Lars Erik; Bråthen, Terje; Hovland, Jon (Peer reviewed; Journal article, 2021)
      Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ...

    • Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS 

      Øi, Lars Erik; Hovland, Jon (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 : 

      Bråthen, Terje; Øi, Lars Erik; Hovland, Jon (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 ...
