A New Extended Corresponding States Equation of State for Modelling CO2-Water Thermodynamics - A Compromise for CFD
Ibrahim, Mohamed (Doctoral theses at NTNU;2017:264, Doctoral thesis, 2017)This PhD work is part of the CO2 Dynamics project in collaboration with Sintef Energy. We investigated the importance of accurate modelling of CO2 thermodynamic properties for process design. The study was conducted for ... -
An Extended Corresponding States Equation of State (EoS) for CCS Industry
Ibrahim, Mohamed; Skaugen, Geir; Ertesvåg, Ivar Ståle (Journal article; Peer reviewed, 2015)For a good design of all the processes in Carbon Capture and Storage, the thermodynamics of the CO2 and CO2 mixtures should be accurately predicted. Among these mixtures are CO2-water systems that are very difficult to ... -
Modelling CO2 - water mixture thermodynamics using various equations of state (EoSs) with emphasis on the potential of the SPUNG EoS
Ibrahim, Mohamed; Skaugen, Geir; Ertesvåg, Ivar Ståle; Haug-Warberg, Tore (Journal article; Peer reviewed, 2014)CO2–water is a very important mixture in the Carbon Capture and Storage (CCS) industry. The mixture can have a broad range of concentrations, from water as an impurity in CO2 transport to high water concentrations in ... -
Modelling CO2-water thermodynamics using SPUNG equation of state (EOS) concept with various reference fluids
Ibrahim, Mohamed; Skaugen, Geir; Ertesvåg, Ivar Ståle (Journal article; Peer reviewed, 2014)Due to the continuous increase of CO2 emission to environment, the Carbon Capture and Storage (CCS) processes gained a very high importance in the last decades. One common CO2 impurity during various CCS processes is water. ... -
Preliminary Evaluation of the SPUNG Equation of State for Modelling the Thermodynamic Properties of CO2 - Water Mixtures
Ibrahim, Mohamed; Skaugen, Geir; Ertesvåg, Ivar Ståle (Journal article; Peer reviewed, 2012)The accuracy of the extended corresponding state equation SPUNG is preliminary evaluated for the density, and Vapor Liquid Equilibrium (VLE) calculations of the CO2 -water mixtures. The evaluation is done by comparing the ... -
PVTx Modeling of CO2 Pipeline at Depressurization Conditions Using SPUNG Equation of State (EoS) with a Comparison to SRK
Ibrahim, Mohamed; Ertesvåg, Ivar Ståle (Journal article; Peer reviewed, 2014)The proper modeling of CO2 depressurization is very important for the design for safety of a pipeline. One key element of the modeling process is the thermodynamics and transport properties modeling. In this work, an ...
