Abstract

Mathematical models were developed for two operational modes of the injector-type extraction column upon separation of the initial mixture. On the basis of a numerical experiment comparison of the cyclic operational mode with the stationary operational mode was carried out with respect to the extraction degree and the energy demand. It was confirmed that, as compared to the stationary operational mode, the cyclic operational mode provides a greater degree of extraction. The ratio of the extraction degrees in these operational modes of the extractor depending on the mass transfer criterion is of an extremal type. The maximum value of this ratio falls within the range from 1 to 4 and is equal to 1.5. It was also shown that the stationary operational mode of the extractor is more energy consuming than the cyclic one. The ratio of the energy demand for the stationary operational mode of the extractor to the energy demand in the cyclic operational mode depends on the extraction degree. This ratio grows from 1 to 5 within the interval of the extraction degree from 0.1 to 0.47.
