ORGANOBENTONIT QATLAMIDA DINAMIK (KOLONNALI) ADSORBSIYA VA TOʻYINISH EGRI CHIZIQLARINI MODELLASHTIRISH

Referat

Mazkur maqolada suv tarkibidagi neft mahsulotlarini samarali ajratib olish maqsadida organobentonit adsorbentining dinamik adsorbsiya jarayonlari tadqiq etilgan. Tajribalar uzluksiz ishlovchi kolonna sharoitida olib borilib, adsorbsiya samaradorligiga ta’sir etuvchi asosiy omillar – adsorbent qatlamining balandligi, filtratsiya jarayonidagi hajmiy sarf hamda ifloslantiruvchi moddaning boshlang‘ich konsentratsiyasi kompleks ravishda baholangan. Olingan natijalar asosida breakthrough (to‘yini sh) egri chiziqlari qurilib, adsorbsiya jarayonining kinetik va massa almashinish qonuniyatlari tahlil qilingan. Tadqiqot davomida adsorbsiya kolonnasining ishlash samaradorligini prognozlash va tavsiflash uchun Thomas, Yoon – Nelson, Adams – Bohart hamda BDST (Bed Depth Service Time) matematik modellari qo‘llanilgan. Modellar yordamida organobentonitning dinamik adsorbsiya sig‘imi, kolonnaning xizmat muddati hamda optimal ekspluatatsion ko‘rsatkichlari aniqlangan. Natijalar adsorbent qatlam balandligining ortishi bilan massa almashinish zonasining kengayishi va kolonnaning ishlash davomiyligi uzayishini, hajmiy sarfning oshishi esa adsorbsiya samaradorligining ma’lum darajada pasayishiga olib kelishini ko‘rsatdi. Hisob - kitoblar va eksperimental ma’lumotlar asosida organobentonitning maksimal dinamik adsorbsiya sig‘imi 57 mg/g ni tashkil etishi aniqlangan. Shu bilan birga, bo‘sh qatlamda kontakt vaqti (EBCT) uchun optimal qiymat 20 daqiqa, filtrlash tezligi esa 5 m/soat deb belgilangan. Tadqiqot natijalari organobentonit asosidagi adsorbentlardan neft mahsulotlari bilan ifloslangan oq ova suvlarni tozalash texnologiyalarida samarali foydalanish mumkinligini ko‘rsatadi hamda sanoat miqyosidagi adsorbsion qurilmalarni loyihalash uchun ilmiy - amaliy asos bo‘lib xizmat qiladi.
