Experimental Determination of Continuous Phase Overall Mass Transfer Coefficients Case Study: Kühni Extraction Column

The aim of this study is to explore the capability of subcritical methanol to reduce the acidity of naphthenic acids and to determine reaction kinetics for large-scale reactor design.The experiments were carried out in a 25 mL autoclave reactor (China) at temperatures of 70-120oC, Methanol Partial Pressures (MPPs) of 0.1-1.5 MPa, and reaction times of 0-60 min. The total...

Advanced Prediction of Pulsed Extraction Column Performance using LLECMOD

A bivariate population balance model (the base of LLECMOD program) for the dynamic simulation of liquid extraction columns is extended to simulate pulsed and sieve extraction columns. The model is programmed using visual digital FORTRAN and then integrated into the LLECMOD program. In addition pulsed and sieve tray columns, LLECMOD simulates stirred two types of agitated columns (RDC & Kühni). ...

Prediction of Dispersed Phase Holdup in the Kühni Extraction Column Using a New Experimental Correlation and Artificial Neural Network

In this work, the dispersed phase holdup in a Kühni extraction column is predicted using intelligent methods and a new empirical correlation. Intelligent techniques, including multilayer perceptron and radial basis functions network are used in the prediction of the dispersed phase holdup. To design the network structure and train and test the networks, 174 sets of experimental data are used. T...

Bioreduction of uranium in a contaminated soil column.

The bioreduction of soluble uranium [U(VI)] to sparingly soluble U(IV) species is an attractive remedial technology for contaminated soil and groundwater due to the potential for immobilizing uranium and impeding its migration in subsurface environments. This manuscript describes a column study designed to simulate a three-step strategy proposed for the remediation of a heavily contaminated sit...

Column Profiles for Membrane Column Sections

A novel graphical method of analysing continuous membrane separation systems has been developed. The method is applicable to all counterand co-current membrane modules – single-stage, cascades, and membrane columns. All configurations can be broken down into “column sections”, no matter how complex the arrangement. Each column section, which resembles a typical single-stage separator, is modell...
