Abstract

In this study, we aimed to determine the optimum operating conditions for the production of ethyl acetate (EtAc) through the esterification of ethanol (EtOH) with acetic acid (HAc) in a reactive distillation (RD) column. For this, the designed column was simulated for the production of EtAc. HAc flow rate, EtOH flow rate, HAc feed stage, EtOH feed stage, reflux ratio, and reactive feed temperatures were changed and the effects of these parameters on EtAc production were observed. Central Composite Design was employed to define the optimum operating conditions for the RD column. The determination coefficient R² was equal to 0.9197 suggesting a good relationship between the predicted and simulated responses. Adjusted R² and predicted R² values obtained from the program were 0.8823 and 0.7956, respectively. The optimal conditions for the EtAc production response were HAc flow rate of 120.00 kmol/h, EtOH flow rate of 150.00 kmol/h, HAc feed stage 6, EtOH feed stage 14, reflux ratio 2.2, and feed temperature 70.28 °C, which were designated by the maximum desirability function.

Etil Asetat Üretimi için Bir Reaktif Distilasyon Kolonunun Dinamik Simülasyonu: Cevap Yüzey Yöntemi ile İşletme Koşullarının Optimizasyonu

Abstract

Bu çalışmada, etanolün (EtOH) asetik asit (HAc) ile reaktif distilasyon (RD) kolonunda, esterleştirilmesi yoluyla etil asetat (EtAc) üretimi için optimum çalışma koşullarının belirlenmesi amaçlanmıştır. Bunun için tasarlanan kolonun EtAc üretimi için simüle edilmiştir. HAc akış hızı, EtOH akış hızı, HAc besleme aşaması, EtOH besleme aşaması, geri akış oranı ve reaktif besleme sıcaklıkları değiştirilmiş ve bu parametrelerin EtAc üretimi üzerindeki etkileri gözlemlenmiştir. RD kolonu için optimum çalışma koşullarını tanımlamak için Merkezi Kompozit Tasarım kullanılmıştır. Regresyon katsayısı R², 0.9197'ye eşittir ve bu, tahmin edilen ve simüle edilen yanıtlar arasında iyi bir ilişki olduğunu göstermiştir. Programdan elde edilen düzeltilmiş ve tahmin edilen R² değerleri sırasıyla 0.8823 ve 0.7956'dır. EtAc üretim yanıtı için optimal koşullar, 120.00 kmol/saat HAc akış hızı, 150.00 kmol/saat EtOH akış hızı, HAc besleme aşaması 6, EtOH besleme aşaması 14, geri akış oranı 2.2 ve reaktif besleme sıcaklığı 70.28 °C olarak maksimum istenilirlik fonksiyonu ile belirlenmiştir.
