The manifold of the workable flow sheets was synthesized. The each flow sheet was optimized by the criteria of the scheme minimum energy consumption. The optimal flow sheet was found which characterized by the energy consumption lower than other ones for 50-75%.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрен процесс экстрактивной ректификации смеси циклогексан- бензол-этилбензол-н-пропилбензол в комплексах из двухотборных колонн. Синтезированы возможные работоспособные варианты организации процесса. Каждое из полученных решений подвергнуто параметрической оптимизации по критерию минимальных суммарных затрат энергии в кубах колонн. Получено оптимальное по заданному критерию технологическое решение, имеющее энергозатраты в 2-3 раза меньшие, чем остальные.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Тимошенко А.В., Серафимов Л.А. //ТОХТ, 1999, т.33, №1, с.47-53.</mixed-citation><mixed-citation xml:lang="en">Тимошенко А.В., Серафимов Л.А. //ТОХТ, 1999, т.33, №1, с.47-53.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Серафимов Л.А., Мозжухин А.С., Науменкова Л.Б. //ТОХТ, 1993, т.27, №3, с.292-299.</mixed-citation><mixed-citation xml:lang="en">Серафимов Л.А., Мозжухин А.С., Науменкова Л.Б. //ТОХТ, 1993, т.27, №3, с.292-299.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Bauer M.
