CO2 absorption with membrane contactors vs. packed absorbers-Challenges and opportunities in post combustion capture and natural gas sweetening
Hoff, Karl Anders; Svendsen, Hallvard Fjøsne (Peer reviewed; Journal article, 2013)The present work presents a case study where membrane contactors are compared with absorption towers for post combustion CO2 capture and for natural gas sweetening. Simulations are performed using a absorber model which ... -
Direct Air capture (DAC) deployment: A review of the industrial deployment
Bisotti, Filippo; Hoff, Karl Anders; Mathisen, Anette; Hovland, Jon (Peer reviewed; Journal article, 2024)Currently, scientists and investors consider Direct Air Capture (DAC) as one of the candidates to reduce CO2 emissions. The emissions cut is pressing since 30% of the current greenhouse gas emissions must be addressed by ... -
Direct air capture (DAC) deployment: National context cannot be neglected. A case study applied to Norway
Bisotti, Filippo; Hoff, Karl Anders; Mathisen, Anette; Hovland, Jon (Peer reviewed; Journal article, 2023)DAC deployment is still an open question. Recent publications focused on energy consumption and the relationship between the cost of captured CO2 and operating conditions. These works addressed a preliminary assessment of ... -
Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis
Kim, Inna; Chikukwa, Actor; Kvamsdal, Hanne ,; Hoff, Karl Anders; Mejdell, Thor; Haugen, Geir (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous ... -
Profiting from CCS innovations: A study to measure potential value creation from CCS research and development
Størset, Sigmund Østtveit; Tangen, Grethe; Berstad, David Olsson; Eliasson, Peder; Hoff, Karl Anders; Langørgen, Øyvind; Munkejord, Svend Tollak; Roussanaly, Simon; Torsæter, Malin (Journal article; Peer reviewed, 2019)Globally, large private and public funds are invested into CO2 capture and storage (CCS) research to provide the knowledge and technology required to mitigate CO2 emissions below a sustainable level. A pertinent question ... -

Use of metal-organics based solvents for CO2 capture
Heyn, Richard H; Aronu, Ugochukwu Edwin; Vevelstad, Solrun Johanne; Hoff, Karl Anders; Didriksen, Terje; Arstad, Bjørnar; Blom, Richard (Journal article; Peer reviewed, 2014)There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one ...
