Rectisol process is more efficient in comparison with other physical or chemical absorption methods for gas purification. To implement a real time simulation of Rectisol process, thermodynamic model and simulation strategy are needed. In this paper, a method of modified statistical associated fluid theory with perturbation theory is used to predict thermodynamic behavior of process. As Rectisol process is a highly heat-integrated process with many loops, a method of equation oriented strategy, sequential quadratic programming, is used as the solver and the process converges perfectly. Then analyses are conducted with this simulator.
Graphical abstractRectisol process is promising absorption methods for gas purification. A method of modified statistical associated fluid theory with perturbation theory (PC-SAFT) is used to predict thermodynamic behavior of process. As Rectisol process is a highly heat-integrated process with many loops, a method of equation oriented strategy (EO), with sequential quadratic programming (SQP) method, is used as the solver and the process converges perfectly.Figure optionsDownload full-size imageDownload as PowerPoint slide
