Vacuum crystallization with subsequent solid–liquid separation is a suitable method to produce and separate the temperature-sensitive protein lysozyme. The conventional process performed batch-wise on different devices, which in turn leads disadvantages terms of energy efficiency, contamination risk control. This publication therefore focuses application previously multistage quasi-continuous, ...

The application of liquid–liquid chromatography principles to solvent extraction processes in hydrometallurgy can greatly simplify rare earth metal separation technologies by separating multicomponent mixtures one technological operation. In this study, the chromatographic elements (REEs) multistage columns was experimentally studied under conditions impulse sample injection—single and multiple...

In the field of stabilizer analysis today there is a need for the analytical determination of the decomposition or transformation products of the stabilizers in polymer systems including their reaction products with the polymers. For the solution of such a complex analytical task, separation problems are at the centre of modern scientific work. These separation problems are subdivided into two ...

The influence of the spent electron beam parameters on possibilities multistage energy recovery in prototype gyrotron developed for DEMO project is determined. characteristics electrodes and magnetic coils a collector with four-stage were optimized considering distributions electrons' coordinates velocities obtained as result calculating electron-wave interaction cavity. In trajectory analysis ...

We propose a new algorithm for blind source separation (BSS), in which frequency-domain independent component analysis (FDICA) and time-domain ICA (TDICA) are combined to achieve a superior source-separation performance under reverberant conditions. Generally speaking, conventional TDICA fails to separate source signals under heavily reverberant conditions because of the low convergence in the ...

In the present study, a computational model to simulate separation of multi-stage device is developed and used verify an arbitrary-shaped adsorption isotherm limited mass transfer rate. The model’s governing equations are solved numerically by MATLAB computing platform. For specific separation, suitable design must take into account concentration record effluent solutions in device. Further, si...
