MAQOLA ANNOTATSIYASI

quote
Amin asosidagi erituvchilar, xususan, metildietanolamin (MDEA) va dietanolamin (DEA)ning issiqlikka bardoshli tuzlar (HSS) to‘planishi natijasida yemirilishi kislotali gazlarni ajratib olish tizimlarining samaradorligi, xavfsizligi va barqarorligiga jiddiy tahdid soladi. Kuchli asosli anionli smolalar yordamida ion almashinish usuli HSSni yo‘qotish uchun keng qo‘llanadigan amaliy usullardan biridir. Biroq ushbu jarayonning optimallashtirilishi hamda boshqaruvi uning noaniqva ko‘p omilli tabiati sababli murakkab bo‘lib qolmoqda. Ushbu tadqiqotda ion almashinish orqali tozalangandan so‘ng eritmada qolgan HSS miqdori va yakuniy pH darajasini bashorat qilish uchun sun’iy neyron tarmoqlar asosidagi bashorat- lash modeli ishlab chiqildi. Modelni o‘rgatish uchun MATLAB muhitida sanoatga oid asosiy texnologik parametrlar – dastlabki HSS konsentratsiyasi, amin miqdori, oqim tezligi, boshlang‘ich pH va harorat bo‘yicha o‘zgaruvchanlikni o‘z ichiga oluv-chi keng qamrovli ma’lumotlar to‘plami yaratildi. Sun’iy neyron tarmoq arxitekturasi ikki yashirin qatlamli feedforward (oldinga yo‘naltirilgan) neyron tarmog‘idan tashkil topgan bo‘lib, u Bayesiy regulyarizatsiya usuli asosida o‘qitildi. Bu usul ortiqcha moslashuvga (overfitting) yo‘l qo‘ymasdan kuchli o‘rganishni ta’minladi. Model yuqori korrelyatsiya koeffitsiyentlariga erishdi: umumiy bashoratlashda R = 0.9586, HSS konsentratsiyasi uchun R = 0.9173 va pH bashorati uchun R = 0.9898. Xatoliklar gistogrammalari kam va simmetrik taqsimlangan qoldiq qiymatlarni ko‘rsatdi, bu modelning aniqligi va umumlashtirish qobiliyatini tasdiqlaydi. Natijalar shuni ko‘rsatdiki, sun’iy neyron tarmoq erituvchilarni tozalash tizimlarida real vaqt rejimida monitoring qilish va bashoratli boshqaruv uchun ishonchli model sifatida xizmat qilishi mumkin. Taklif etilgan metodologiya kimyo muhandisligi sohasi-da intellektual jarayonlarni optimallashtirishga hissa qo‘shib, operatsion samaradorlikni oshirish va atrof -muhitga salbiy ta’sirni kamaytirishga yordam beradi.
