Это легковоспламеняющийся и бесцветный газ при температуре выше 11 °C. Это важный товарный химикат для производства растворителей, антифриза, текстиля, моющих средств, клея, полиуретановой пены и фармацевтических препаратов. Небольшие количества оксида этилена [EO] используются в производстве фумигантов и стерилизаторов для специй и косметики, а также для стерилизации хирургического оборудования в больницах. Современные производства оксида этилена [EO] используют либо воздух, либо кислород (O2) для окисления этилена (C2H4) с помощью серебряного катализатора на носителе из оксида алюминия [Ag/Al2O3]катализатор упакован в реактор с неподвижным слоем (plug-flow reactor), но процесс кислородно-основной реакции более желателен, здесь мы использовали кислород. В основном происходят две реакции, частичное окисление этилена до оксида этилена и полное окисление этилена до диоксида углерода и воды. Проектные модели процесса в данном исследовании основаны на трехкомпонентной системе. Это: реакционная система, система абсорбции и система очистки этиленоксида [ЭО]. Наибольшие затраты в производстве оксида этилена приходятся на этилен, поэтому важно оптимизировать селективность по отношению к оксиду этилена и таким образом снизить потребление этилена. Целью данной работы является создание имитационной модели процесса производства оксида этилена из этилена с использованием Aspen Hysys V9. А также определение оптимальных рабочих условий (температура - давление - скорость потока) для реакций окисления этилена. Моделирование проводилось три раза с различными рабочими условиями для получения хорошего результата. В результате был сделан вывод, что в течение рабочего времени энергия активации увеличивается для обеих реакций, что должно быть компенсировано увеличением температуры реактора. В то же время селективность для получения окиси этилена снижается, т.е. образуется больше углекислого газа и воды. Имитационные модели дают оксид этилена с чистотой 99,2%.</p></abstract><trans-abstract xml:lang="en"><p>This research has been performed in the Ethylene Oxide production process. It is a flammable and colorless gas at temperatures above 11 °C. It is an important commodity chemical for the production of solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals. Small amounts of Ethylene Oxide [EO] are used in manufacturing fumigants and sterilants for spices and cosmetics, as well as hospital sterilization for surgical equipment. Modern Ethylene oxide [EO] productions employ either air or oxygen (O2)to oxidize ethylene (C2H4) with  a silver catalyst on an alumina oxide carrier[Ag/Al2O3]catalyst packed in a fixed-bed reactor (plug-flow reactor)but the oxygen-base reaction process is more desirable   here we used oxygen. Mainly two reactions occur, partial oxidation of ethylene to ethylene oxide and total oxidation of ethylene to carbon dioxide and water. The design models of the process in this research based on a three-part system. They are: the reaction system, absorption system and Ethylene Oxide [EO] purification system. The largest cost in production of ethylene oxide is ethylene therefore, it’s important to optimize the selectivity towards ethylene oxide and thus reduce the consumption of Ethylene. The aim of this work is to create a simulation model of the Ethylene Oxide production process from Ethylene using Aspen Hysys V9. Also to knowing the optimum operational conditions (temperature –pressure –flow rate) for the oxidation reactions of Ethylene. The simulation was running three times with various operational conditions to   make a good result. The conclusion was that during operational time the activation energy increased for both reactions which have to be compensated with increasing reactor temperature. At the same time the selectivity for producing Ethylene Oxide decreases, i.e. more carbon dioxide and water are formed. The simulation models yield Ethylene Oxide with purity of 99.2%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>моделирование</kwd><kwd>твердые бытовые отходы</kwd><kwd>газификация</kwd><kwd>реактор с неподвижным слоем</kwd><kwd>пиролиз</kwd><kwd>энергия гиббса</kwd><kwd>модель ргиббса</kwd><kwd>газификатор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Simulation</kwd><kwd>Municipal solid</kwd><kwd>Gasification</kwd><kwd>Fixed bed reactor</kwd><kwd>Pyrolysis</kwd><kwd>Gibbs energy</kwd><kwd>Rgibbs model</kwd><kwd>Gasifier</kwd></kwd-group><funding-group><funding-statement xml:lang="en">University of El Imam El Mahdi, Sudan</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bayat M., Hamidi M., Dehghani Z., Rahimpour M.R.
