Effect of lifter shape and operating parameters on the flow of materials in a pilot rotary kiln: Part I. Experimental RTD and axial dispersion study

Powder Technology, 2015
Experiments on the residence time distribution (RTD) and axial dispersion for the continuous flow of sand and broken rice, through a pilot scale rotary kiln at room temperature and equipped with lifters, are reported. Factors such as the rotational speed,

Use of the Dispersion Coefficient as the Sole Structural Parameter to Model Membrane Chromatography

Membranes, 2022
The characterization and modelling of membrane chromatography processes require the axial dispersion coefficient as a relevant and effective intrinsic property of porous media, instead of arbitrary assumptions on pore size distribution.

Axial dispersion of the liquid phase on a three-phase Karr reciprocating plate column [PDF]

Journal of the Serbian Chemical Society, 2004
The influence of the gas flow rate and vibration intensity in the presence of the solid phase (polypropylene spheres) on axial mixing of the liquid phase in a three phase (gas-liquid-solid) Karr reciprocating plate column (RPC) was investigated. Assuming

A Generic and Effective System Dispersion Compensation Method: Development and Validation in Visible-Light OCT

Photonics, 2023
Compared with optical coherence tomography (OCT) in the near-infrared domain, the visible-light OCT (vis-OCT) system affords a higher axial resolution for discerning subtle pathological changes associated with early diseases.

Reciprocating plate column - fundamental research and application in Serbia from 1970 to 2020 [PDF]

Hemijska Industrija
In the group of multiphase contactors and reactors, an important place belongs to reciprocat-ing plate columns (RPCs), which consist of a set of perforated plates fixed on a carrier (the so-called reciprocating or vibrating agitator) moving periodically ...
