ATIK YEMEKLİK YAĞDAN YAĞ ASİDİ METİL ESTERİ ÜRETİMİ İÇİN REAKTİF DAMITMA SİSTEMİNDE HETEROGEN KATALİZLİ TRANSESTERİFİKASYONUN KİNETİK MODELLEMESİ, DENEYSEL TASARIMI VE PROSES SİMÜLASYONU

Öz

Bu çalışmada, yağ asidi metil esteri (FAME) üretimi için kullanılan reaktif distilasyon prosesinin simülasyonu gerçekleştirilmiştir. Proses için kullanılan reaktif distilasyon kolonu, Aspen HYSYS'te distilasyon kolonu akışkan paketi kullanılarak kurulmuştur. Kullanılan model General NRTL modelidir. Kolon, kondenser bölümü, reaksiyon bölümü, sıyırma bölümü ve reboiler bölümü olmak üzere dört bölüme ayrılmıştır. Atık yemeklik yağ (WCO) ve metanol, kolonun besleme bölümünden kolona girmiştir. Geliştirilen model, Sparse Continuation Solver kullanılarak yakınsama için simüle edilmiştir. Aspen HYSYS reaktif distilasyon modelinde gerçekleştirilen simülasyondan elde edilen iyi yakınsama, Aspen HYSYS'in bu süreci başarıyla gerçekleştirebildiğini göstermiştir. Sonuç olarak, optimum çalışma parametreleri 0,1 geri akma oranı, 18,5 W ısıtıcı gücü, 11,2 × 10⁻⁴ kgmol/h toplam besleme hızı ve 6,14 metanol-WCO molar oranı olarak belirlenmiştir. Bu koşullar altında, maksimum %98,07 dönüşüm elde edilmiştir. Bu nedenle, bu çalışmada geliştirilen Aspen HYSYS modelinin, FAME reaktif distilasyon sürecini başarıyla simüle etmek için kullanılabileceği gösterilmiştir.

KINETIC MODELING, EXPERIMENTAL DESIGN AND PROCESS SIMULATION OF HETEROGENEOUSLY CATALYZED TRANSESTERIFICATION IN A REACTIVE DISTILLATION SYSTEM FOR FATTY ACID METHYL ESTER PRODUCTION FROM WASTE COOKING OIL

Öz

In this work, the simulation of a reactive distillation process used for the production of fatty acid methyl ester (FAME) has been carried out. The reactive distillation column used for the process was set up in Aspen HYSYS using Distillation Column fluid package employed was General NRTL model. The column was divided into four sections, condenser section, reaction section, stripping section and reboiler section. Waste cooking oil (WCO) and methanol entered the column through feed section of the column. The developed model was simulated to convergence using Sparse Continuation Solver. The good convergence obtained from the simulation carried out on the developed Aspen HYSYS model of the reactive distillation process showed that Aspen HYSYS has been able to handle this process successfully. As a result, the optimum operating parameters were established as follows: : a reflux ratio of 0.1, a reboiler duty of 18.5 W, a total feed rate of 11.2 × 10⁻⁴ kgmol/h, and a methanol-to-WCO molar ratio of 6.14. Under these conditions, a maximum conversion of 98.07% were achieved. Therefore, it has been shown that the developed Aspen HYSYS model of this research work can be used to represent and simulate a FAME reactive distillation process successfully.
