Abstract

Penelitian ini bertujuan untuk meningkatkan efisiensi proses distilasi bioetanol yang terkendala oleh rendahnya performa perpindahan massa pada sieve tray konvensional. Sebagai solusi, diusulkan penerapan wire mesh packing di atas tray untuk memperluas area kontak uap cair. Kinerja dari konfigurasi packed sieve tray ini dievaluasi melalui simulasi Computational Fluid Dynamics (CFD) menggunakan model Eulerian multiphase, turbulensi k-ε, dan species transport. Tujuan spesifik penelitian ini adalah untuk (1) mempelajari profil hidrodinamika yang dihasilkan oleh penambahan packing, dan (2) mengetahui pengaruhnya terhadap fraksi massa etanol, efisiensi Murphree, dan liquid height.
Hasil simulasi pada tray ke-2 hingga ke-5 dengan variasi tinggi packing (3 cm dan 5 cm) menunjukkan bahwa, sesuai dengan tujuan pertama, penambahan wire mesh packing menciptakan distribusi kecepatan uap yang lebih homogen dibandingkan Raschig ring yang cenderung mengalami channeling. Sejalan dengan tujuan kedua, penambahan packing terbukti meningkatkan fraksi massa etanol, menaikkan liquid height hingga 28,5%, dan meningkatkan efisiensi Murphree, dengan performa tertinggi dicapai oleh wire mesh setinggi 5 cm.
Disimpulkan bahwa penambahan wire mesh packing secara efektif mengoptimalkan kinerja sieve tray melalui perbaikan hidrodinamika dan peningkatan transfer massa, yang menjawab hipotesis awal penelitian.

This study aims to improve the efficiency of the bioethanol distillation process, which is
constrained by the low mass transfer performance of conventional sieve trays. As a solution, the application of wire mesh packing on top of the trays is proposed to expand the vapor-liquid contact area. The performance of this packed sieve tray configuration was evaluated through Computational Fluid Dynamics (CFD) simulations using the Eulerian multiphase, k-ε turbulence, and species transport models. The specific objectives of this research were to (1) study the hydrodynamic profile resulting from the addition of packing, and (2) determine its effect on the ethanol mass fraction, Murphree efficiency, and liquid height.
The simulation results on trays 2 through 5, with packing height variations (3 cm and 5
cm), demonstrated that, in accordance with the first objective, the addition of wire mesh
packing creates a more homogeneous vapor velocity distribution compared to Raschig rings, which tend to exhibit channelling. In line with the second objective, the addition of packing was proven to increase the ethanol mass fraction, raise the liquid height by up to 28.5%, and improve Murphree efficiency, with the highest performance achieved by the 5 cm high wire mesh.
It is concluded that the addition of wire mesh packing effectively optimizes sieve tray performance through improved hydrodynamics and enhanced mass transfer, thus confirming the initial research hypothesis.
