Vapor-liquid equilibrium data for the carbon dioxide and nitrogen (CO2+N2) system at the temperatures 223, 270, 298 and 303 K and pressures up to 18 MPa

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1278561

A new setup for the measurement of vapor-liquid phase equilibria of CO2-rich mixtures relevant for carbon capture and storage (CCS) transport conditions is presented. An isothermal analytical method with a variable volume cell is used. The apparatus is capable of highly accurate measurements in term...

Vapor-liquid equilibrium data for the carbon dioxide and oxygen (CO2 + O2) system at the temperatures 218, 233, 253, 273, 288 and 298 K and pressures up to 14 MPa

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1349305

Accurate thermophysical data for the CO2-rich mixtures relevant for carbon capture, transport and storage (CCS) are essential for the development of the accurate equations of state (EOS) and models needed for the design and operation of the processes within CCS. Vapor-liquid equilibrium measurements...

CO2 transport: Data and models – A review

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1326936

This review considers data and models for CO2 transport. The thermophysical properties of CO2 and CO2-rich mixtures are needed as a basis for various models within CO2 capture and storage (CCS). In particular, this is true for transient models of pipes and vessels. Here, the data situation for phase...

Formulating the optimization problem when using sequential quadratic programming applied to a simple LNG process

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1252833

Sequential quadratic programming (SQP) may be very efficient compared with other techniques for the optimization of simple processes for the liquefaction of natural gas (LNG), and can be combined with process evaluation using commercial flowsheet simulators. However, the level of success is dependen...
