Mercury Behaviour in Gas-Condensate-Monoethylene Glycol (MEG) Systems
(Master thesis, 2016)Gas and condensate production gets more challenging as the exploration takes place in deeper and in lower quality reservoirs. Under certain conditions, hydrate plugging is a major problem, causing damages to pipes and ... -
Mesostructured alumina and the state of Ni as promoter for Co Fischer-Tropsch synthesis catalysts
(Doctoral Theses at NTNU, 1503-8181; 2014:227, Doctoral thesis, 2014)Supported cobalt catalysts are widely studied and applied for conversion of synthesis gas in low temperature Fischer-Tropsch (FT) synthesis. It is common practice to add a noble metal promoter to optimize the performance ... -
Metaheuristic Framework for Material Screening and Operating Optimization of Adsorption-Based Heat Pumps
(Peer reviewed; Journal article, 2023)The current methods applied to material screening for adsorption-based heat pumps are based on a fixed set of temperatures or their independent variation, providing a limited, insufficient, and unpractical evaluation of ... -
