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

Modelling aspects of carbon dioxide capture technologies using porous contactors: a review

“…Recently, Yu et al [74] had made an investigation on CO 2 absorption in packed column by means of MEA using a CFD approach and found a good agreement between the Downloaded by [University of Winnipeg] at 06: 38 25 August 2014 simulated results and the experimental ones. One of the acclaimed approaches by them was the synergy between the fluid flow, heat/mass transfer and chemical reaction using the Lagrangian field model with an understanding of the spontaneity of the reaction.…”

Characterizing the catalyst fluidization with field synergy to improve the amine absorption for CO2 capture

“…During the catalyst fluidization for desorption of CO 2 , the key point is to characterize the effects of catalyst fluidization on the desorption process. The field synergy theory and Density Functional Theory (DFT) [23][24][25][26] are able to be extended to characterize the catalyst fluidization effects by considering that it can include the multi-field effects, which are important phenomena in the catalyst fluidization. It is obvious that catalyst fluidization will make the multi-field effects more complicated induced by catalyst motion and collision.…”

“…In order to solve the model, SIMPLE algorithm is used to solve the differential equations and additional source term method is used to improve the convergence [36][37]. Since the numerical solution is much more difficult for the gas-liquid-solid three phases cases in the fluidized reactor, the initial parameters are set by referencing the parameter distributions obtained in the packed reactor in the literatures [38]. This can further increase the solution speed due to that these parameter distributions are more close to that in the fluidized reactor than the conventional uniform initial parameters set.…”

Exploiting an Alternative CO2 Absorption Process by Efficient Solvent Mixture

“…29 The liquid U is obtained by the liquid phase momentum equation, which is typically used for absorption of CO 2 in amine solutions. 27,30 The typical energy equation is used to determine the temperature distribution, 7,31 where the experiment reaction heat in Table 1 is used to revise the source term.…”
