Simulations of chemical absorption in pilot-scale and industrial-scale packed columns by computational mass transfer

Dynamic simulation of MEA absorption process for CO2 capture from power plants

“…One of the most widely used mass transfer coefficients is that proposed by Onda et al (1968) and validated by Bravo and Fair (1982). Several studies on MEA absorption process have used this correlation (Pacheco, 1998;Liu et al, 2006;Kvamsdal et al, 2009;Ghaemi et al, 2009 …”

Research on Mass Transfer Columns: passé?

“…The development of criteria that drastically reduce the product development and market introduction timeline would be preferable to current testing. CFD and computational mass transfer (CMT) can be important tools for this type of research; Liu and Yin have published initial interesting approaches to this effect [37,38].…”

Performance improvement for chemical absorption of CO2 by global field synergy optimization

“…The reason is that the viscous dissipation and coupled heat and mass transfer only contributes to small part of entropy generation. As for the heat transfer effect, it seems an unimportant point in the capture process (Liu et al, 2006b), so the varying trend is omitted. However, the three terms in the overall energy performance are still incorporated below.…”

“…The additional source term method was employed to improve the computational process. The boundary conditions were cited from the literatures (Liu et al, 2006b;Kvamsdal et al, 2009). The convergence was reached when the relative imbalance mass was less than 1 × 10 −3 .…”
