Hozirgi kunda yer yuzi aholisi iqlim oʻzgarishlari ta’siridan aziyat chekmoqda. Iqlim oʻzgarishlarining asosiy sabablaridan biri – bu issiqxona gazlari, xususan, karbonat angidridning atmosferadagi konsentratsiyasi oshib ketishidir. Antropogen ta’sirlar tufayli karbonat angidridning atmosferadagi konsentratsiyasi sanoat inqilobi boshlangandan buyon qariyb 1,5 barobar ortgan. Sement ishlab chiqarish jarayoni ham CO2 emissiyasining asosiy manbalaridan biri hisoblanib, global miqyosda yiliga 2,3 Gt CO2 ni atmosferaga emissiya qilmoqda. Ushbu ishda sement ishlab chiqarish sanoatida tutun gazlaridan CO2 ni ajratish jarayoni tahlil qilindi. Dastlab yiliga 1 Mt sement ishlab chiqarish zavodi Aspen Plus dasturida modellashtirildi. Keyingi bosqichda esa sement zavodi tutun gazlari tarkibidagi CO2 ni kamaytirishga qaratilgan usullardan membrana vositasida ushlab qolish texnologiyasi modeli tuzildi. Ushbu model asosida 90 %dan kam boʻlmagan ushlab qolish samaradorligi hamda 95 %dan kam boʻlmagan CO2 tozaligi shartlari uchun zarur membrana yuzasi va bosimlar farqi qiymatlari aniqlandi.

В настоящее время население Земли страдает от последствий изменения климата. Одной из основных причин изменения климата является увеличение концентрации в атмосфере парниковых газов, в частности CO2 . Из-за антропогенного воздействия концентрация СО2 в атмосфере с начала индустриальной революции увеличилась почти в 1,5 раза. Процесс производства цемента также считается одним из основных источников выбросов CO2 : во всём мире в атмосферу выбрасывается 2,3 Гт CO2 в год. В данной работе был проанализирован процесс сепарации CO2 из дымовых газов цементной промышленности. Первоначально в программном обеспечении Aspen Plus был смоделирован завод по производству цемента мощностью 1 млн т в год. На следующем этапе была построена модель технологии мембранной сепарации, состоящая из способов снижения CO2 в дымовых газах цементного завода. На основе разработанной модели определены необходимая площадь мембраны и значения перепада давления для условий эффективности улавливания СО2 не менее чем 90 % и его чистоты не менее чем 95 %.
Currently, the population of the Earth is suffering from problems caused by climate change. One of the main reasons for climate change is the increased concentration of greenhouse gases, in particular carbon dioxide (CO2 ), in the atmosphere. Owing to anthropogenic effects, the CO2 concentration in the atmosphere has increased by almost 1.5 times since the pre-industrial revolution. The cement production process is also considered one of the main sources of CO2 emissions, globally emitting 2.3 Gt of CO2 per year into the atmosphere. This study looks into the process of CO2 capture from flue gases in the cement plant. Initially, a cement plant with a 1 Mt/year capacity was modeled in Aspen Plus software. At the next stage, a model of membrane-based CO2 capture was built in order to reduce CO2 emissions in cement plants. According to the developed model, the required membrane surface and pressure drop values have been determined for the constraints of capture efficiency as at least 90% and CO2 purity as not less than 95%.
