Multistream Countercurrent Heat Exchangers

, 1973
An idealized model multistream countercurrent exchanger is considered. It comprises a number of parallel two-dimensional streams in channels separated by thin conductive partitions.

Enantioseparation using a counter-current bioreactor

, 2011
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The potential of countercurrent chromatography (CCC) as a small footprint bioreactor/separator for manufacture of enantiopure chiral molecules was explored,

Experimental Study on Smoke Spreading Laws for Tunnel Fires with Moving Fire Source

Fire
Compared with a stationary fire, the spread of smoke in a moving fire source is more complex, which means hazardous consequences. The study of smoke flow and distribution of ceiling temperature is essential for effective emergency response strategies and

Liquid–liquid equilibria and NRTL modeling for thiophene extraction from nC12, nC14 and nC16 using bis(trifluoromethylsulfonyl)imide–based pyrrolidinium and pyridinium ionic liquids

Chemical Thermodynamics and Thermal Analysis
Liquid–liquid equilibrium (LLE) data were determined at 313.15 K and 101.3 kPa for ternary systems containing thiophene, n-dodecane, n-tetradecane, or n-hexadecane, and the ionic liquids [C3C1Pyr][NTf₂], [C4C1Pyr][NTf₂], and [C6Py][NTf₂].

Elution-extrusion countercurrent chromatography separation of six pairs of isomeric iridoids fromCornus officinalisSieb. et Zucc. guided by ion current extraction in mass spectrometry

, 2018
A mass spectrometry-guided elution-extrusion countercurrent chromatography protocol was developed to separate chemical components from Cornus officinalis Sieb. et Zucc. In this study, ion current extraction, a mass spectrometry-based data postacquisition

Ultraefficient reduced model for countercurrent two-layer flows [PDF]

, 2017
We investigate the dynamics of two superposed layers with density contrast flowing countercurrent inside a channel, when the lower layer is much thinner than the wavelength of interfacial waves.

Mathematical modelling of salt purification by recrystallization. Countercurrent arrangement

, 1986
The paper presents a simple model of recrystallization with countercurrent flows of the solution and the crystals being purified. The model assumes steady-state operating conditions, an equilibrium between the outlet streams of each stage, and the same ...
