The phenomenon of internal energy saving on theoretical plates is considered in detail. As shown in this article, the phenomenon depends on the number of theoretical plates in the rectifying and stripping sections of the column and also on the aggregative state of the feed mixture. The processes of heat and mass transfer on real plates with various values of efficiency factor are considered. Blocks of real plates equivalent to one theoretical stage, that is, blocks where the leaving flows of the liquid and vapor are in equilibrium, are isolated. Analogically, heat and mass transfer in apparatuses with a continuous phase contact having a layer height providing one theoretical plate is considered. It is proved that internal energy saving in filled rectifying columns with real plates also depends on the number of theoretical plates and the aggregative state of the initial mixture.</p></abstract><trans-abstract xml:lang="ru"><p>Проанализированы перспективные способы экономии затрат теплоты при ректификации жидких смесей. Подробно рассмотрено явление внутреннего энергосбережения на теоретических тарелках. Показано, что оно зависит от числа теоретических тарелок в укрепляющей и отгонной частях колонны, а также от агрегатного состояния исходной смеси. Исследованы процессы тепломассообмена на реальных тарелках с различными значениями КПД. Выделены блоки реальных тарелок, эквивалентные одной теоретической ступени, т.е. в которых уходящие потоки жидкости и пара равновесны. По аналогии с этим рассмотрен тепломассобмен в аппаратах с непрерывным контактом фаз с высотой слоя, обеспечивающей одну теоретическую тарелку. Доказано, что в насадочных ректификационных колоннах и в колоннах с реальными тарелками внутреннее энергосбережение также зависит от числа теоретических тарелок и агрегатного состояния исходной смеси.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ректификация</kwd><kwd>энергосбережение</kwd><kwd>внутреннее энергосбережение</kwd><kwd>теоретическая тарелка</kwd><kwd>реальная тарелка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>distillation</kwd><kwd>energy saving</kwd><kwd>internal energy saving</kwd><kwd>theoretical stage</kwd><kwd>real stage</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Захаров М.К.
