Pemisahan Campuran Etanol-Oktanol-Air dengan Metode Distilasi dalam Structured Packing

Abstract

Keberadaan bahan bakar minyak (BBM) yang merupakan bahan bakar berbahan fosil sudah menjadi suatu kebutuhan utama masyarakat dunia, namun keberadaannya saat ini semakin menipis. Salah satu potensi yang relatif besar adalah pengembangan bioetanol menggunakan metode fermentasi ekstraktif. Hasil bioetanol dari metode fermentasi ekstraktif masih rendah, yaitu sekitar 15% sehingga diperlukan penelitian untuk pemurniannya. Tujuan dari penelitian ini adalah mendapatkan kadar etanol tertinggi dengan metode distilasi dalam structured packing. Dari hasil penelitian didapatkan pada variabel suhu 80ᵒC pada porositas 20%, 40% dan 60% didapatkan kadar etanol sebesar 88,24% ; 91,95% dan 85,85%.
