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

Types of gas fluidization
TL;DR: The behavior of solids fluidized by gases falls into four clearly recognizable groups, characterized by density difference (ϱs −ϱf) and mean particle size as discussed by the authors, and a numerical criterion which distinguishes between groups A and B has been devised and agrees well with published data.
