The Individual

A new method for separating fibrous coatings and backing materials of automotive components is introduced. The selective performance of high-speed water jets with velocities up to 300 m/s is utilized to mill backing materials from textile card webs without fibre damage, and selectively to remove textile coatings from luggage boot linings, insulating sheets and columns. The individual separation processes are discussed. The particular material removal process depends on the structure and properties of the compounds. Permeability plays an important role. It is shown that any individual separation process is characterized by an energy threshold, and typical values for these thresholds are provided. The new method is a very reliable tool for selective separation. Quality aspects as well as economical aspects are also discussed.

Mixtures that contain a known target component but are otherwise poorly specified 15 are important in many fields. Previously, the activity of the target component, which is needed e.g. to design separation processes, could not be predicted in such mixtures. A method was developed to solve this problem. It combines a thermodynamic group contribution method for the activity coefficient with NMR spectroscopy, which is used for estimating the nature and amount of the different chemical groups in the mixture. The knowledge of the component 20 speciation of the mixture is not required. Test cases that are inspired by bioprocess engineering applications show that the new method gives surprisingly good results.

Optimization Of Separation

For more than 60 years, the accepted wisdom has been that the methods of optimizing separation processes based on quantitative criteria are fundamentally different from those based on separation curves. The present article demonstrates a functional relation between these two approaches. Reposing upon this relation, we propose a new method for the optimization of separation processes, which combines the advantages of both approaches, namely the availability of a quantitative evaluation and invariance of the evaluation with respect to the grain-size distribution of the starting material.
