TLDR
In this article, the authors proposed a method to predict the distribution of residence-times in large systems by using distribution-functions for residencetimes, which can be used to calculate the etficiencies of reactors and blenders.About:

Predictive Simulation of Gas Adsorption in Fixed-Beds and Limitations due to the Ill-Posed Danckwerts Boundary Condition
TL;DR: In this paper, a 1D axially dispersed plug flow model is used for the simulation of adsorption processes, where the axial dispersion coefficient and the Glueckauf linear driving force are individually fit to specific test data that isolates the appropriate physics.

A Discontinuous-Galerkin Finite-Element Method for Simulation of Packed Bed Chromatographic Processes
Alexander Horsholt,Lasse Hjuler Christiansen,Kristian Meyer,Jakob Kjøbsted Huusom,John Bagterp Jørgensen +4 more
TL;DR: A discontinuous-Galerkin method on finite-elements for spatial discretization and low storage explicit Runge-Kutta (LSERK) methods for numerical solution of the resulting system of differential equations of packed bed chromatographic processes are used.

Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
TL;DR: In this article, the nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra series and generalized Fourier transform.

Evaluation of surfactant flooding using interwell tracer analysis
TL;DR: In this paper, the authors evaluated two surfactant mechanisms in non-fractured carbonate reservoirs using UTCHEM, the University of Texas chemical compositional simulator, to evaluate the effects of surfactants on both fluid and rock-fluid interactions.

The Definition and Measurement of Some Characteristics of Mixtures
TL;DR: In this paper, it is shown that the important features of such mixtures can be expressed by two statistically defined quantities, the scale and the intensity of segregation, and methods of measuring these are suggested.
