AN EXAMPLE OF FIXED-BED REACTOR DESIGN FO R AN ELECTROCHEMICAL PROCESS OF VANADIUM OXIDATION IN WASHING SOLUTIONS

Washing solutions for carbon dioxide separation in the nitrogen indust ry may contain pentavalent vanadium, which, unfortunately, is reduced to the tetravalent form. An electrochemical reoxidation could be an al ternative to the conventional oxidation by air. Based upon experimenta l studies and calculations, with the help of a mathematical fixed bed reactor model, a process quantification was carried out for a given ox idation capacity. Parameter studies allowed process conditions and cel l design to be optimized. The results show, that the electroenergy cos ts are relatively low and are not a limiting factor in the processing.
