Программа Aspen Hysys внедрена на Атырауском НПЗ впервые. Проведены расчеты по оптимизации узлов установок первичной переработки нефти АВТ-3 и АТ-2 Атырауского НПЗ с построением модели в Aspen Hysys. В результате расчетов выявлена возможность повышения эффективности работы установок, для подтверждения проведены опытные пробеги на установках. В ходе опытного пробега на установке АВТ-3 выявлено ограничение по регулированию температуры куба отпарной колонны, что влияет на стабилизацию начала кипения керосиновой фракции. В ходе опытного пробега на установке АТ-2 выявлено, что повышение расхода пара в основную колонну атмосферной перегонки нефти способствует снижению содержания светлых фракций в прямогонном мазуте, при этом увеличиваются выходы бензиновой и керосино-газойлевой фракций. Таким образом, показан положительный эффект применения программы Aspen Hysys на Атырауском НПЗ для оптимизации установок первичной перегонки нефти и выявления технологических ограничений.</p></abstract><trans-abstract xml:lang="en"><p>The article shows examples of the use of Aspen Hysys software for optimization of the AVT-3 and AT-2 crude oil distillation units at Atyrau Oil Refinery. The Aspen Hysys software was implemented at the Atyrau Refinery for the first time.Calculations were carried out to optimize AVT-3 and AT-2 crude distillation units of the Atyrau refinery with the construction of a model in Aspen Hysys. As a result of the calculations, the possibility of improving the efficiency of individual parts of units was revealed, pilot runs on the units were carried out to confirm. During the pilot run on the AVT-3 unit, a restriction was revealed on regulating the temperature of the cube of the steam column, which affects the stabilization of the kerosene fraction beginning boiling point. During the pilot run at the AT-2 unit, it was revealed that an increase in steam consumption in the main atmospheric oil distillation column contributes to a decrease in the content of light fractions in straight-run fuel, while the yields of gasoline and kerosene-gasoil fractions increase. Thus, the positive effect of Aspen Hysys application at the Atyrau refinery for optimization of crude oil distillation units and identification of technological limitations is shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Hysys</kwd><kwd>инженерное моделирование</kwd><kwd>установка атмосферной перегонки нефти</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hysys</kwd><kwd>engineering modeling</kwd><kwd>crude oil distillation unit</kwd><kwd>optimization</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">Osuolale F.N., Jie Zhang.
