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...

CO2 Capture from Off-shore Gas Turbines Using Supersonic Gas Separation ☆

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1190264

CO2 capture from gas turbine based off-shore application face challenges such as size (foot-print), weight and stability (wave motion) in addition to the challenges faced by on-shore industry. Space- and weight challenges are given priority, and the size of the capture installations will be of impor...

Constraint handling in stochastic optimization algorithms for natural gas liquefaction processes

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1033998

Liquefaction of natural gas requires energy intensive refrigeration. A fair comparison of different process concepts and energy efficient designs requires some use of optimization. In near optimal designs, the driving forces in heat transfer are small. Thus, rigorous thermodynamics providing accurat...

Time efficient solution of phase equilibria in dynamic and distributed systems with DAE-solvers

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+981721

Solution of phase equilibria with flash calculations is central in many processes. During the integrating of the conservation equations in these systems, flash calculations are traditionally solved in inner loops at each integration step. Some of these systems can be solved more efficiently using mo...
