Boosting carbon efficiency of the biomass to liquid process with hydrogen from power: The effect of H2/CO ratio to the Fischer-Tropsch reactors on the production and power consumption
Ostadi, Mohammad; Rytter, Erling; Hillestad, Magne (Journal article; Peer reviewed, 2019)Carbon efficiency of a biomass to liquid process can be increased from ca. 30 to more than 90% by adding hydrogen generated from renewable power. The main reason is that in order to increase the H2/CO ratio after gasification ... -
Conceptual Design of a Once‐Through Gas‐to‐Liquid Process Combined with Ammonia Synthesis
Ostadi, Mohammad; Hillestad, Magne (Journal article; Peer reviewed, 2018)Recently, a new process has been proposed for a once‐through gas‐to‐liquid (GTL) plant suitable for offshore applications. Here, cogeneration of ammonia is suggested. This is firstly because the main ingredients for ammonia ... -
Exergy Analysis of a Process Converting Power and Biomass to a Liquid Fuel
Ostadi, Mohammad; Austbø, Bjørn; Hillestad, Magne (Journal article; Peer reviewed, 2019)A power and biomass to liquid process (PBtL) via Fischer-Tropsch synthesis is exergetically analysed. Synthesis gas is generated through an entrained flow gasifier and extra hydrogen is produced through high temperature ... -
Improving carbon efficiency and profitability of the biomass to liquid process with hydrogen from renewable power
Hillestad, Magne; Ostadi, Mohammad; del Alamo Serrano, Gonzalo; Rytter, Erling; Austbø, Bjørn; Pharoah, Jon; Burheim, Odne Stokke (Journal article; Peer reviewed, 2018)A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept. Based on detailed process models, it is demonstrated that the ... -
New and Innovative Conceptual Designs of Gas-to-Liquid Processes
Ostadi, Mohammad (Doctoral theses at NTNU;2017:205, Doctoral thesis, 2017)The research is about a chemical process, which turns natural gas into liquid fuel through chemical reactions, and it is called Gas-to-Liquid (GTL) process. The produced liquid fuel is a replacement for liquid fuel derived ... -
Parametric Optimization of a Power and Biomass to Liquid Process
Ostadi, Mohammad; Austbø, Bjørn; Hillestad, Magne (Chapter, 2019)In this study, a power & biomass to liquid process (PBtL) is optimized with respect to nine continuous design variables. These variables have great impact on the profitability of the process. A detailed process model is ... -
Process Integration of Green Hydrogen: Decarbonization of Chemical Industries
Ostadi, Mohammad; Paso, Kristofer Gunnar; Rodriguez Fabia, Sandra; Øi, Lars Erik; Manenti, Flavio; Hillestad, Magne (Journal article; Peer reviewed, 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 ...
