A new approach for chemical transfer reaction models

Modeling CO2 Capture in Amine Solvents: Prediction of Performance and Insights on Limiting Phenomena

“…This driving force accounts for all the forces tending to move each species in the solution, and especially the effect of a chemical potential gradient. In electrolytic systems, an electrostatic term can be added to the driving force, but this term has no influence on the mass transfer in alkanolamines systems (see the work of Benjelloun-Dabagh et al).…”

“…At the interface between the liquid film and the bulk, the boundary conditions are c i = c i B ⁣ i = 1 , ..., N C At ξ = δ: This model has extensively been used to represent the absorption of acid gases, , but also for determining the kinetic parameters for gas–liquid reactive absorption. , The knowledge of the film thickness (δ) is needed to integrate along the diffusion film. This thickness depends on the species but can be estimated by considering the diffusion of MEACOO – and assuming that the film thickness is not modified by chemical reactions: δ = k MEACOO − , eff L D MEACOO − , eff L Equations – define a two-point boundary value problem.…”
