Abstrak
Kinerja alat distilasi etanol ditentukan oleh jenis reboiler yang digunakan pada kolom distilasi. Penelitian ini bertujuan untuk menentukan pengaruh perbedaan diameter dan tinggi tabung internal reboiler, serta kadar umpan terhadap kadar etanol distilat dan rendemen distilasi. Penelitian dilakukan pada proses distilasi etanol secara batch menggunakan alat distilasi rektifikasi dengan internal reboiler jenis Vertical Tubular Baffle yang berbeda ukuran diameter dan tinggi tabungnya, yaitu diameter 1,5, 1 dan 0,5 inci, serta tinggi tabung 8, 6 dan 4 cm. Bahan atau umpan pada penelitian ini adalah larutan etanol berkadar 10%, 20% dan 30% v/v. Hasil penelitian didapatkan kadar etanol distilat yang paling tinggi dengan kadar rata-rata 97,17% v/v dicapai pada proses distilasi dengan internal reboiler berukuran diameter 0,5 inci, dan tinggi tabung 8 cm dan kadar umpan 10%. Geometri berpengaruh pada proses perpindahan panas di dalam internal reboiler suatu alat distilasi sehingga berpengaruh terhadap hasil distilasi.
