С целью её снижения выполнена оценка возможности уменьшения расхода пара при регенерации пропана из асфальтового раствора. Исследование проводили с использованием моделирующей системы Honeywell UniSim Design, в которой сформировали модель установки пропановой деасфальтизации гудрона. В качестве математического пакета для расчета термодинамических свойств компонентов фракций использовали метод Peng-Robinson. Компонентный состав сырья представлен нефтяными фракциями с температурами кипения от 405 до 616 ?. При проведении вычислительного эксперимента использовали следующие значения технологических параметров: расход гудрона 38.9 т/час, отношение (пропан: сырье) составляло (6.4:1), выход деасфальтизата порядка 30 %мас. Выполненный анализ типовой схемы регенерации пропана из асфальтового раствора показал, что в технологическом потоке, поступающем на питание отпарной колонны К-6, уже присутствует достаточно большое количество паровой фазы, состоящей практически из пропана и следов нефтяных фракций. Для эффективного использования энергии потока без привлечения дополнительных энергетических затрат целесообразно разделить газовую и жидкую фазы до их поступления в колонну К-6, то есть перед ней включить в технологическую схему дополнительный сепаратор. Проведенный вычислительный эксперимент показал, что в предложенном варианте технологической схемы требуемый для выделения пропана расход пара уменьшается на 17,5 %, что соответственно для последующих аппаратов схемы снижает количество воды, сбрасываемой в канализацию. Оптимизация технологических режимов отпарной колонны К6 обеспечивает четкое выделение пропана, в потоке которого содержание битумных фракций составляет 0.03% мол., что делает возможным в промышленных условиях возвращать поток пропана на питание экстракционной колонны. Предлагаемое технологическое решение для регенерации пропана может использоваться в процессах одно- и двухступенчатой деасфальтизации гудрона.</p></abstract><trans-abstract xml:lang="en"><p>For propane tar deasphalting units, a rather high energy intensity of the technological process is characteristic. In order to reduce it, an assessment was made of the possibility of reducing the steam consumption during the regeneration of propane from asphalt solution. The study was carried out using a Honeywell UniSim Design modeling system, in which a model of a propane tar deasphalting unit was formed. The Peng-Robinson method was used as a mathematical package for calculating the thermodynamic properties of the components of the fractions. The component composition of the feedstock is represented by oil fractions with boiling points from 405 to 616 °C. When carrying out a computational experiment, the following values of technological parameters were used: the tar consumption was 38.9 t / h, the ratio (propane: raw material) was (6.4: 1), the yield of deasphalted oil was about 30 wt%. The performed analysis of a typical scheme for the regeneration of propane from asphalt solution showed that in the process stream supplied to the feed of the stripping column K-6, there is already a sufficiently large amount of a vapor phase consisting practically of propane and traces of oil fractions. To efficiently use the energy of the flow without attracting additional energy costs, it is advisable to separate the gas and liquid phases before they enter the column K-6, that is, to include an additional separator in the technological scheme before it. The performed computational experiment showed that in the proposed version of the technological scheme, the steam consumption required for the release of propane decreases by 17.5%, which, accordingly, for the subsequent devices of the scheme, reduces the amount of water discharged into the sewage system. Optimization of technological modes of the stripping column K-6 provides a clear separation of propane, in the flow of which the content of bitumen fractions is 0.03 mol%, which makes it possible in industrial conditions to return the flow of propane to the feed of the extraction column. The proposed technological solution for propane recovery can be used in the processes of one- and two-stage tar deasphalting.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гудрон</kwd><kwd>пропан</kwd><kwd>установка деасфальтизации гудрона</kwd><kwd>деасфальтизат</kwd><kwd>раствор асфальта</kwd><kwd>сепаратор</kwd><kwd>отпарная колонна</kwd><kwd>энергосбережение</kwd><kwd>Honeywell UniSim Design</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tar</kwd><kwd>propane</kwd><kwd>tar deasphalting plant</kwd><kwd>deasphalting</kwd><kwd>asphalt solution</kwd><kwd>separator</kwd><kwd>stripping column</kwd><kwd>energy saving</kwd><kwd>Honeywell UniSim Design</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">Халикова Д.А., Петров С.М., Башкирцева Н.Ю.
