In world practice, technologies for cleaning exhaust gases from nitrogen oxides, sulfur and ash are actively used. However, carbon dioxide captures technologies have not yet found wide application due to a significant decrease in the efficiency of electricity production. This paper presents the results of the development and study of process flow charts of binary and trinary power plants with minimal emissions of harmful substances into the atmosphere. The research revealed that the transition from monoethanolamine cleaning of exhaust gases to a methane steam reforming plant provides an increase in the net efficiency of a trinary power plant by 1.25% (for a combined-cycle plant by 1.16%) and a reduction in specific carbon dioxide emissions into the atmosphere by 2.3 times. The high efficiency of the power unit with an integrated steam methane reforming unit compared to monoethanolamine exhaust gas cleaning is due to a reduction in electricity costs for carbon dioxide capture by 8.2 MW.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящий момент повышение экологической безопасности на тепловых энергетических станциях является одним из ключевых направлений развития энергетики. В мировой практике активно применяются технологии очистки уходящих газов от оксидов азота, серы и золы. Однако технологии улавливания диоксида углерода до сих пор не нашли широкого применения из-за существенного снижения эффективности производства электроэнергии. В настоящей работе представлены результаты разработки и исследования технологических схем бинарных и тринарных парогазовых установок с минимальными выбросами вредных веществ в атмосферу. В ходе исследований было выявлено, что переход от моноэтаноламиновой очистки уходящих газов к установке паровой конверсии метана обеспечивает прирост КПД нетто тринарной энергетической установки на 1.25% (для парогазовой установки на 1.16%) и сокращение удельных выбросов диоксида углерода в атмосферу в 2.3 раза. Большая эффективность энергоблока с интегрированной установкой паровой конверсии метана по сравнению с моноэтаноламиновой очисткой уходящих газов обусловлена снижением затрат электроэнергии на улавливание углекислого газа на 8,2 МВт.</p></trans-abstract><kwd-group xml:lang="en"><kwd>combined-cycle plants</kwd><kwd>steam methane reforming</kwd><kwd>thermodynamic analysis</kwd><kwd>thermal schemes</kwd><kwd>energy efficiency</kwd><kwd>organic Rankine cycle</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>парогазовые установки</kwd><kwd>паровая конверсия метана</kwd><kwd>термодинамический анализ</kwd><kwd>тепловые схемы</kwd><kwd>энергетическая эффективность</kwd><kwd>органический цикл Ренкина</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>FSWF-2023-0014</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Энергетическая стратегия Российской Федерации на период до 2035 года | Министерство энергетики РФ [Электронный ресурс].
