Process intensification for post-combustion CO2 capture with chemical absorption: A critical review
TL;DR: In this paper, the authors evaluated different process intensification (PI) technologies for their suitability in post-combustion CO2 capture (PCC) using solvent process is one of the most mature carbon capture technologies There are two main barriers for PCC process using solvent to be commercially deployed: (a) high capital cost; (b) high thermal efficiency penalty due to solvent regeneration

Statistical thermodynamics of liquid mixtures: A new expression for the excess Gibbs energy of partly or completely miscible systems
D. S. Abrams,John M. Prausnitz +1 more
TL;DR: The UNIQUAC equation as discussed by the authors is a semi-theoretical equation for the excess Gibbs energy of a liquid mixture, which is generalized through introduction of the local area fraction as the primary concentration variable.

Local composition model for excess Gibbs energy of electrolyte systems. Part I: Single solvent, single completely dissociated electrolyte systems
TL;DR: In this paper, an electrolyte local composition model is developed for excess Gibbs energy, which is assumed to be the sum of two contributions, one resulting from long range electrostatic forces between ions and the other from short range forces between all the species.

A local composition model for the excess Gibbs energy of aqueous electrolyte systems
TL;DR: In this article, Chen et al. generalized the NRTL model to represent the excess Gibbs energy of aqueous multicomponent electrolyte systems and used binary parameters to predict deviation from ideality.
