At what Pressure Shall CO2 Be Transported by Ship? An in-Depth Cost Comparison of 7 and 15 Barg Shipping
Roussanaly, Simon; Deng, Han; Skaugen, Geir; Gundersen, Truls (Peer reviewed; Journal article, 2021)The pipeline has historically been the preferred means to transport CO2 due to its low cost for short distances and opportunities for economies of scale. However, interest in vessel-based transport of CO2 is growing. While ... -
Boiling and Condensation Heat Transfer of Zeotropic Mixtures in Smooth Tubes
Deng, Han (Doctoral thesis at NTNU;2016:330, Doctoral thesis, 2016)Boiling and condensation of mixtures are widely encountered in liquefaction of natural gas process, refrigeration systems, and other chemical and power generation industries. Zeotropic mixtures present a temperature glide ... -
Comparing Three Methods for Design Analyses of Rankine Cycle for Waste Heat Recovery from Natural Gas Compression
Deng, Han; Hagen, Brede; Nikolaisen, Monika; Andresen, Trond (Chapter, 2020)This study applies three methods for design of Rankine cycles utilizing waste heat in the oil and gas industry. The methods differ in the level of detail of heat exchanger model applied and in the flexibility with respect ... -
Depressurization of in a pipe: Effect of initial state on non-equilibrium two-phase flow
Log, Alexandra Metallinou; Hammer, Morten; Deng, Han; Austegard, Anders; Hafner, Armin; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
Hammer, Morten; Deng, Han; Austegard, Anders; Log, Alexandra Metallinou; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
Investigation of non-equilibrium effects during the depressurization of carbon dioxide
Log, Alexandra Metallinou; Munkejord, Svend Tollak; Hammer, Morten; Hafner, Armin; Deng, Han; Austegard, Anders (Chapter, 2022)Predicting the phase change of liquid CO2 during depressurization is highly relevant for the application in refrigeration units and for safety analysis in the context of CO2 capture and storage (CCS). For abrupt depressurization ... -
A novel methodology for design optimization of heat recovery steam generators with flow-induced vibration analysis
Deng, Han; Skaugen, Geir; Næss, Erling; Zhang, Mingjie; Øiseth, Ole Andre (Peer reviewed; Journal article, 2021)Design of compact, lightweight, and robust heat recovery steam generators (HRSGs) is important for the implementation of offshore bottoming cycles. In this work, a novel methodology integrating flow-induced vibration ...
