Kinerja Internal Reboiler Tipe Vertical Tubular Baffle pada Proses Distilasi Etanol secara Batch

The performance of ethanol distillation is determined by the type reboiler used in column. This study aims to determine effect differences diameter and height internal tubes, as well feed content on distillate concentration yield. research was conducted a batch process using rectified device with an vertical tubular baffle different diameters tube height, namely 1.5, 1, 0.5 inches diameter, 8, 6, 4 cm heights. Materials or feeds this were solutions levels 10%, 20%, 30% v/v. results showed that highest 97.17% v/v (average) achieved 0.5”, 8 cm, 10%. Geometry affected heat transfer so it results.Keywords: distillation; ethanol; reboiler: performanceA B S T R A KKinerja alat distilasi etanol ditentukan oleh jenis yang digunakan pada kolom distilasi. Penelitian ini bertujuan untuk menentukan pengaruh perbedaan dan tinggi tabung reboiler, serta kadar umpan terhadap distilat rendemen dilakukan proses secara menggunakan rektifikasi dengan Vertical Tubular Baffle berbeda ukuran tabungnya, yaitu 1,5, 1 0,5 inci, 6 cm. Bahan atau penelitian adalah larutan berkadar 20% Hasil didapatkan paling rata-rata 97,17% dicapai berukuran Geometri berpengaruh perpindahan panas di dalam suatu sehingga hasil distilasi.Kata kunci: distilasi; etanol; reboiler; kinerja
