This article investigates the inhibitory effects of asphaltenes and resinous components on various stages of crude oil processing, including distillation, catalytic cracking, and pipeline transportation. These high-molecular-weight, polar compounds tend to aggregate, leading to increased viscosity, equipment fouling, catalyst deactivation, and flow assurance challenges. Their chemical complexity and strong intermolecular interactions make them particularly resistant to conventional separation techniques.

The article reviews state-of-the-art neutralization strategies, including chemical dispersants, surface-active agents, and nanomaterial-based solutions. Experimental insights into additive performance, interaction kinetics, and process optimization are presented to evaluate their practical applicability.

В этой статье исследуется ингибирующее действие асфальтенов и смолистых компонентов на различных этапах переработки сырой нефти, включая дистилляцию, каталитический крекинг и транспортировку по трубопроводу. Эти высокомолекулярные полярные соединения имеют тенденцию к агрегации, что приводит к повышению вязкости, загрязнению оборудования, дезактивации катализатора и проблемам обеспечения потока. Их химическая сложность и сильные межмолекулярные взаимодействия делают их особенно устойчивыми к традиционным методам разделения. В статье рассматриваются современные стратегии нейтрализации, включая химические диспергаторы, поверхностно-активные вещества и решения на основе наноматериалов. Представлены экспериментальные данные об эффективности присадок, кинетике взаимодействия и оптимизации процесса для оценки их практической применимости.

Ushbu maqolada asfaltenlar va smolasimon komponentlarning xom neftni qayta ishlashning turli bosqichlariga, jumladan distillash, katalitik kreking va quvur orqali tashishga ingibirlovchi ta‘siri o‘rganiladi. Ushbu yuqori molekulyar og‘irlikka ega qutbli birikmalar agregatlanishga moyil bo‘lib, bu qovushqoqlikning ortishiga, uskunalarning ifloslanishiga, katalizatorning faolsizlanishiga va oqimni ta‘minlash muammolariga olib keladi. Ularning kimyoviy murakkabligi va kuchli molekulalararo o‘zaro ta‘siri ularni an‘anaviy ajratish usullariga ayniqsa chidamli qiladi. Maqolada neytrallashning zamonaviy strategiyalari, jumladan kimyoviy dispergatorlar, sirt-faol moddalar va nanomateriallarga asoslangan yechimlar ko‘rib chiqiladi. Qo‘shimchalar samaradorligi, o‘zaro ta‘sir kinetikasi va jarayonni optimallashtirish bo‘yicha eksperimental ma‘lumotlar ularning amaliy qo‘llanilishini baholash uchun taqdim etilgan.
